jQuery: Check if an element exists or not

We can make use of the .length property in jQuery to know if an element exists or not in the HTML page DOM.

The .lenght property returns a count of the number of elements that are present on the page. If there is no match then the count is zero.


<div id="welcome">
Welcome to Code2care.org

<div id="tagline">
Code2dcare - Lines of code for a change!

if ($('#welcome').length > 0) {
    console.log("Element exists.");
} else {
    console.log("Element doesn't exist.");

Element exists.
