如何在Html中调用页面加载类[关闭]

I have jquery with class= modal i want to call that class when page load how to do using javascript or php

You can use either

$(document).ready(function(){ /*Code Here/* }); 

(which is equivalent to $(function(){ /*Code Here/* });)
to execute the code when the DOM is ready, or you can use

$(document).load(function(){ /*Code Here/* });

to execute the code once all sub-elements have also been loaded, i.e. images.

To do something after page has been loaded, use jQuery like:

$(function(){
   // code that should run after page has finished loading
});

You can put your code just before the </body> tag, like this:

    <script type="text/javascript>
        $('.modal')....
    </script>
</body>
