如何使用jQuery检查具有自定义属性和特定值的输入字段

Question

I have input fields with custom attributes. i want to check if input field with custom attribute has specific value then alert match else not match.

(function ($) {
    $(".my_class").click(function () {
        var custom_attr = $(this).attr('custom_attr');
        $("input").each(function () {
            var condation = $(this).attr('condation');
            if (condation == custom_attr) {
                alert('match');
            } else {
                alert('not match');
            }
        });
    });
})(jQuery);

I think you can try a regex bases test like

 if (!RegExp.escape) { RegExp.escape = function(value) { return value.replace(/[\\-\\[\\]{}()*+?.,\\\\\\^$|#\\s]/g, "\\\\$&") }; } (function($) { $(".my_class").click(function() { var custom_attr = $(this).attr('custom_attr'); var regex = new RegExp(custom_attr.split(/\\s+/).map(function(value) { return '(\\\\b' + RegExp.escape(value) + '\\\\b)' }).join('|')); $('input').each(function() { var condation = $(this).attr('condation'); if (regex.test(condation)) { alert('match'); } else { alert('not match'); } }); }); })(jQuery); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div> <button type="button" name="abc" class="my_class" custom_attr="field1 field2">Match</button> </div> <div> <input name="def" condation="field1 user_defined" /> <input name="jkl" condation="field2 user_defined" /> <input name="jkl" condation="field13 user_defined" /> </div>
