1 -> List
List is a component used to display a list, which contains a series of list items of the same width, which is suitable for presenting the same kind of data in consecutive rows.
1.1 -> Create a List component
Create a List component in the hml file in the pages/index directory.
<!-- index.hml -->
<div class="container">
<list>
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
</list>
</div>
/* test.css */
.container {
width:100%;
height:100%;
flex-direction: column;
align-items: center;
background-color: #F1F3F5;
}
.listItem{
height: 20%;
background-color:#d2e0e0;
margin-top: 20px;
}
illustrate
is a subcomponent of the to implement the list grouping function, and can no longer nest < list>, but can nest .
is a subcomponent of the that displays specific items in the list.
1.2 -> Add scrollbars
Set the scrollbar property to ON to generate a scrollbar on the right side of the screen to achieve effects such as long lists or screen scrolling.
<!-- index.hml -->
<div class="container">
<list class="listCss" scrollbar="on" >
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
<list-item class="listItem"></list-item>
</list>
</div>
/* index.css */
.container {
flex-direction: column;
background-color: #F1F3F5;
}
.listItem{
height: 20%;
background-color:#d2e0e0;
margin-top: 20px;
}
.listCss{
height: 100%;
scrollbar-color: #8e8b8b;
scrollbar-width: 50px;
}
1.3 -> Add a side index bar
When you set the indexer property to a custom index, the index bar is displayed at the right edge of the list, and the indexer property is set to true, which is an alphabetic index table by default.
<!-- index.hml -->
<div class="container">
<list class="listCss" indexer="{
{['#','1','2','3','4','5','6','7','8']}}" >
<list-item class="listItem" section="#" ></list-item>
</list>
</div>
/* index.css */
.container{
flex-direction: column;
background-color: #F1F3F5;
}
.listCss{
height: 100%;
flex-direction: column;
columns: 1
}
illustrate
For the indexer attribute to take effect, the flex-direction attribute must be set to column, and the columns attribute must be set to 1.
The indexer can customize the index table, and the "#" must exist when customizing.
1.4 -> Implement list folding and expansion
Add groupcollapse and groupexpand events to the List component to collapse and expand the list.
<!-- index.hml -->
<div class="doc-page">
<list style="width: 100%;" id="mylist">
<list-item-group for="listgroup in list" id="{
{listgroup.value}}" ongroupcollapse="collapse" ongroupexpand="expand">
<list-item type="item" style="background-color:#FFF0F5;height:95px;">
<div class="item-group-child">
<text>One---{
{listgroup.value}}</text>
</div>
</list-item>
<list-item type="item" style="background-color: #87CEFA;height:145px;" primary="true">
<div class="item-group-child">
<text>Primary---{
{listgroup.value}}</text>
</div>
</list-item>
</list-item-group>
</list>
</div>
/* index.css */
.doc-page {
flex-direction: column;
background-color: #F1F3F5;
}
list-item{
margin-top:30px;
}
.top-list-item {
width:100%;
background-color:#D4F2E7;
}
.item-group-child {
justify-content: center;
align-items: center;
width:100%;
}
// test.js
import prompt from '@system.prompt';
export default {
data: {
direction: 'column',
list: []
},
onInit() {
this.list = []
this.listAdd = []
for (var i = 1; i <= 2; i++) {
var dataItem = {
value: 'GROUP' + i,
};
this.list.push(dataItem);
}
},
collapse(e) {
prompt.showToast({
message: 'Close ' + e.groupid
})
},
expand(e) {
prompt.showToast({
message: 'Open ' + e.groupid
})
}
}
illustrate
The groupcollapse and groupexpand events can be used only by the list-item-group component.
1.5 -> Scenario example
In this scenario, you can search for the corresponding contact based on the alphabetical index.
<!-- index.hml -->
<div class="doc-page">
<text style="font-size: 35px; font-weight: 500; text-align: center; margin-top: 20px; margin-bottom: 20px;">
<span>Contacts</span>
</text>
<list class="list" indexer="true">
<list-item class="item" for="{
{namelist}}" type="{
{$item.section}}" section="{
{$item.section}}">
<div class="container">
<div class="in-container">
<text class="name">{
{$item.name}}</text>
<text class="number">18888888888</text>
</div>
</div>
</list-item>
<list-item type="end" class="item">
<div style="align-items:center;justify-content:center;width:750px;">
<text style="text-align: center;">Total: 10</text>
</div>
</list-item>
</list>
</div>
/* index.css */
.doc-page {
width: 100%;
height: 100%;
flex-direction: column;
background-color: #F1F3F5;
}
.list {
width: 100%;
height: 90%;
flex-grow: 1;
}
.item {
height: 120px;
padding-left: 10%;
border-top: 1px solid #dcdcdc;
}
.name {
color: #000000;
font-size: 39px;
}
.number {
color: black;
font-size: 25px;
}
.container {
flex-direction: row;
align-items: center;
}
.in-container {
flex-direction: column;
justify-content: space-around;
}
// test.js
export default {
data: {
namelist:[{
name: 'Zoey',
section:'Z'
},{
name: 'Quin',
section:'Q'
},{
name:'Sam',
section:'S'
},{
name:'Leo',
section:'L'
},{
name:'Zach',
section:'Z'
},{
name:'Wade',
section:'W'
},{
name:'Zoe',
section:'Z'
},{
name:'Warren',
section:'W'
},{
name:'Kyle',
section:'K'
},{
name:'Zaneta',
section:'Z'
}]
},
onInit() {
}
}
2 -> dialogue
The Dialog component is used to create custom pop-up windows, which are usually used to display information or actions that the user needs or must pay attention to.
2.1 -> Create a Dialog component
Create a Dialog component in the hml file in the pages/index directory and add a Button component to trigger the Dialog. The Dialog component supports only width, height, margin, margin-[left|top|right|bottom], and margin-[start|end].
<!-- test.hml -->
<div class="doc-page">
<dialog class="dialogClass" id="dialogId" dragable="true">
<div class="content">
<text>this is a dialog</text>
</div>
</dialog>
<button value="click me" onclick="openDialog"></button>
</div>
/* test.css */
.doc-page {
width:100%;
height:100%;
flex-direction: column;
align-items: center;
justify-content: center;
background-color: #F1F3F5;
}
.dialogClass{
width: 80%;
height: 250px;
margin-start: 1%;
}
.content{
width: 100%;
height: 250px;
justify-content: center;
background-color: #e8ebec;
border-radius: 20px;
}
text{
width: 100%;
height: 100%;
text-align: center;
}
button{
width: 70%;
height: 60px;
}
/* test.js */
export default {
//Touch to open the dialog box.
openDialog(){
this.$element('dialogId').show()
},
}
2.2 -> Set pop-up responses
When you click on a non-Dialog area on the page, the cancel event will be triggered and the pop-up window will be closed. You can also add show and close methods to the dialog to show and close pop-ups.
<!-- test.hml -->
<div class="doc-page">
<dialog class="dialogClass" id="dialogId" oncancel="canceldialog">
<div class="dialogDiv">
<text>dialog</text>
<button value="confirm" onclick="confirmClick"></button>
</div>
</dialog>
<button value="click me" onclick="openDialog"></button>
</div>
/* test.css */
.doc-page {
width:100%;
height:100%;
flex-direction: column;
align-items: center;
justify-content: center;
background-color: #F1F3F5;
}
.dialogClass{
width: 80%;
height: 300px;
margin-start: 1%;
}
.dialogDiv{
width: 100%;
flex-direction: column;
justify-content: center;
align-self: center;
}
text{
height: 100px;
align-self: center;
}
button{
align-self: center;
margin-top: 20px;
width: 60%;
height: 80px;
}
/* test.js */
import prompt from '@system.prompt';
export default {
canceldialog(e){
prompt.showToast({
message: 'dialogCancel'
})
},
openDialog(){
this.$element('dialogId').show()
prompt.showToast({
message: 'dialogShow'
})
},
confirmClick(e) {
this.$element('dialogId').close()
prompt.showToast({
message: 'dialogClose'
})
},
}
illustrate
Only a single subcomponent is supported.
Dialog attributes and styles cannot be dynamically updated.
The Dialog component does not support the focusable and click-effect attributes.
2.3 -> Scenario example
In this scenario, you can use the Dialog component to implement a schedule. When the pop-up window is open, use the Textarea component to enter the current schedule, click the confirm button to get the current time and save the entered text. Finally, each schedule is displayed in the form of a list.
<!-- test.hml -->
<div class="doc-page">
<text style="margin-top: 60px;margin-left: 30px;">
<span>{
{date}} events</span>
</text>
<div class="btndiv">
<button type="circle" class="btn" onclick="addschedule">+</button>
</div>
<!-- for Render events data -->
<list style="width: 100%;">
<list-item type="item" for="schedulelist" style="width:100%;height: 200px;">
<div class="schedulediv">
<text class="text1">{
{date}} event</text>
<text class="text2">{

}
}
3 -> form
Form is a form container that supports the submission and reset of the content of the Input component in the container.
illustrate
Supported from API Version 6.
3.1 -> Create a Form component
Create a Form component in the hml file in the pages/index directory.
<!-- test.hml -->
<div class="container">
<form style="width: 100%; height: 20%">
<input type="text" style="width:80%"></input>
</form>
</div>
/* test.css */
.container {
width:100%;
height:100%;
flex-direction: column;
justify-content: center;
align-items: center;
background-color: #F1F3F5;
}
3.2 -> Implement form scaling
Add the click-effect attribute to the Form component to achieve the zoom effect after clicking on the form.
<!-- test.hml -->
<div class="container">
<form id="formId" class="formClass" click-effect="spring-large">
<input type="text"></input>
</form>
</div>
3.3 -> Set the Form style
Set the background color and border of the form by adding the background-color and border attributes to the form.
/* test.css */
.container {
width: 100%;
height: 100%;
flex-direction: column;
align-items: center;
justify-content: center;
background-color: #F1F3F5;
}
.formClass{
width: 80%;
height: 100px;
padding: 10px;
border: 1px solid #cccccc;
}
3.4 -> Add a response event
Add submit and reset events to the Form component to submit form content or reset form options.
<!-- test.hml -->
<div class="container">
<form onsubmit='onSubmit' onreset='onReset' class="form">
<div style="width: 100%;justify-content: center;">
<label>Option 1</label>
<input type='radio' name='radioGroup' value='radio1'></input>
<label>Option 2</label>
<input type='radio' name='radioGroup' value='radio2'></input>
</div>
<div style="width: 100%;justify-content: center; margin-top: 20px">
<input type="submit" value="Submit" style="width:120px; margin-right:20px;" >
</input>
<input type="reset" value="Reset" style="width:120px;"></input>
</div>
</form>
</div>
/* index.css */
.container{
width: 100%;
height: 100%;
flex-direction: column;
justify-items: center;
align-items: center;
background-color: #F1F3F5;
}
.form{
width: 100%;
height: 30%;
margin-top: 40%;
flex-direction: column;
justify-items: center;
align-items: center;
}
/* test.js */
import prompt from '@system.prompt';
export default{
onSubmit(result) {
prompt.showToast({
message: result.value.radioGroup
})
},
onReset() {
prompt.showToast({
message: 'Reset All'
})
}
}
3.5 -> Scenario Example
In this scenario, you can select the appropriate option and submit or reset the data.
Create an Input component, set the type attribute to checkbox (multi-checkbox) and radio (radio checkbox), and then use the onsubmit and onreset events of the Form component to submit and reset the form data.
<!-- test.hml -->
<div class="container">
<form onsubmit="formSubmit" onreset="formReset">
<text style="font-size: 30px; margin-bottom: 20px; margin-top: 100px;">
<span > Form </span>
</text>
<div style="flex-direction: column;width: 90%;padding: 30px 0px;">
<text class="txt">Select 1 or more options</text>
<div style="width: 90%;height: 150px;align-items: center;justify-content: space-around;">
<label target="checkbox1">Option 1</label>
<input id="checkbox1" type="checkbox" name="checkbox1"></input>
<label target="checkbox2">Option 2</label>
<input id="checkbox2" type="checkbox" name="checkbox2"></input>
</div>
<divider style="margin: 20px 0px;color: pink;height: 5px;"></divider>
<text class="txt">Select 1 option</text>
<div style="width: 90%;height: 150px;align-items: center;justify-content: space-around;">

<text class="txt">Text box</text>
<input type="text" placeholder="Enter content." style="margin-top: 50px;"></input>
<div style="width: 90%;align-items: center;justify-content: space-between;margin: 40px;">
<input type="submit">Submit</input>
<input type="reset">Reset</input>
</div>
</div>
</form>
</div>
/* index.css */
.container {
width: 100%;
height: 100%;
