In my form, have used html() to append more HTML tags into a div. How can I check element I just append whether there exists or not.
$(".container").html('<div id="divId"></div>');
And check to exist I check as below but it is not working.
if($("#divId").html().length > 0){
// div exists and do something here.
}
Thank you for any suggestions.

In Jquery, you can use .length property to check number of elements or length value of an element. This property will return the number match with your rule defined.
In your code, you are checking value length of div. It is not check element exists. To check element exist you can do as below :
if($("#divId").length > 0){ // div exists and do something here. }and if you using Javascript:
var lengthExist = document.getElementById("divId"); if(lengthExist != null){ // To do something here }I hope it resolves the problem for you.
