Check if control present in main Ul tag or not?

I have following structure.

<ul id="main">
    <li id="a"/>
    <ul id="main1">
        <li id="b"/>
    </ul>
</ul>

In above code when the user clicked on the button, I want to check whether li with id=b present in id=main ul or not using jquery. So pleases let me know how can I check using jquery.

Try this for a check:

if($('#main').has('li[id="b"]').length > 0)

This will check, if main has any li element with id equals b. The result is an array with all elements or zero elements.

You can use below code to achieve what you want

if ($("ul[id='main']").find("li[id='b']").length > 0) 
{
     // Element is present.
}
else 
{
     // Element is not present.
}
