JQuery Check if Element Exists – JS Helpers

JQuery Check if Element Exists using this simple piece of code. To check this in the current page, we need to check the length of the element returned by the JQuery selector, if it returns you something then the element must exists otherwise no.

if( $('#EleSelector').length ) { // use this if you are using id, replace EleSelector with the id
// it exists
}

if( $(‘.EleSelector’).length ) { // use this if you are using class, replace EleSelector with the id
// it exists
}

In case of plain javascript try this:

//you can use it for more advanced selectors
if(document.querySelectorAll("#EleSelector").length){}

//you can use it if your selector has only an Id attribute
if(document.getElementById("EleSelector")){}
