jQuery动态加载表单

I am trying to automatically do some form preprocessing whenever a form gets loaded on my website. This can happen via a normal page load, but also via an AJAX inline page load. So putting it in $(document).ready(function() { /* ... */ }); does not suit my needs.

What I have so far:

$("form").each(function() {
    $(this).ready(function() {
        $(this).find(".input input").each(function() {
            var required = $(this).data("required");
            var checkField = $(this).closest("tr").children(".check");
            var errorField = $(this).closest("tr").children(".errormessage");
            if (required) {
                $(checkField).css("color", "#FFFF00");
                $(checkField).html("✘");
                $(errorField).css("color", "#FFFF00");
                $(errorField).html("(Required)");
            }
            else {
                $(checkField).css("color", "#FFFF00");
                $(checkField).html("✔");
                $(errorField).css("color", "#000000");
                $(errorField).html("");
            }
        });
    });
});

When putting it in $(document).ready(function() { /* ... */ }); it works, but only for the first load. When I'm putting it outside that function, then it never works, it does not even reach the $("form").each(function() { /* ... */ });.

How to fix this?

Could you make a plugin out of this? For example:

 $.fn.formRendering = function(){

     //process your code here
 };

 $('form').formRendering();
