Welcome to my first question here.
I am interested in finding a way to use regex, or any other more efficient method, to identify and delete div B after matching it with div A based on their content. Can you provide some guidance on how to do this?
Here is an example of the HTML code I am working with:
<div class="A"> Hello </div>
<div class="B"> Hello </div>
<div class="C"> Bye </div>
......... and so forth.
There are numerous methods to accomplish this task, one approach involves creating a lookup system
(function (){
var dataLookup = {}; //store data in this object
$("div").each( function () { //iterate through the div elements
var currentElement = $(this); //reference to the current element
var textContent = $.trim(currentElement.text()); //retrieve the text content
if (dataLookup[textContent]) { //check if the text has been encountered before, if yes then remove the current element
currentElement.remove();
} else {
dataLookup[textContent] = true; //add the text to the lookup object
}
});
}());
let elementA = $(".A").text(); //retrieves text content within element A
let elementB = new RegExp($(".B").text()); //retrieves text content within element B
//check for matching text
if(elementA.test(elementB)) {
$(".B").remove(); //removes element B if there is a match
}
Give it a shot!
$("div:not(.A):contains("+$(".A").text()+")").remove()
Check out the code on jsfiddle here
Give it a go and see the magic happen on button click!
<div class="X">Hey </div>
<div class="Y">Hey </div>
<div class="Z">Goodbye </div>
<input type="button" value="press me" id="button" />
$('#button').click(function () {
if ($('.X').text() == $('.Y').text())
{
$(".X").remove();
}
});
