HTML tips

Following are the html tips:

Change the menu

function showHide(anchor)
{
if(anchor.innerHTML.startsWith("Show"))
{
anchor.innerHTML = anchor.innerHTML.replace("Show","Hide");
}
else
{
anchor.innerHTML = anchor.innerHTML.replace("Hide","Show");
}
}

Checking if the div with id exists
ength property will return zero if element does not exists.

if ($("#mydiv").length > 0){
// do something here
}

Getting the child element from the parent element

var parent = document.getElementById('disptable');
parent.querySelector("#boardc");

Setting CSS to the element

function setCSS(eleID) {
var currTabElem = document.getElementById(eleID);
currTabElem.setAttribute("class", "some_class_name");
currTabElem.setAttribute("className", "some_class_name");
}

Show and Hide div element

`Click Me

This is my DIV element.

function myFunction() {
var x = document.getElementById("myDIV");
if (x.style.display === "none") {
x.style.display = "block";
} else {
x.style.display = "none";
}
}`

Creating Text Node

let docs = document.getElementByID('#freelancer');
let elements = freelancer.getElementsByClassName('item');
var td1 = document.getElementById('td1');
var text = document.createTextNode("some text");
td1.appendChild(text);

removing the highlighted marked text

targets = document.querySelectorAll("mark");
for (let target of targets) {
target.outerHTML=target.innerHTML;
}

Getting the table column cell text

$('#td1').html('hello world');
$(tbl).find('tr').each(function(){
var currentRow=$(this);
var column_count = 0;
currentRow.find("td").each(function() {
var currentColumn = $(this);
var col_value = currentColumn.text();
});
});
