    javascript - jQuery's val() is not working on a hidden field - Stack Overflow

    programmeradmin6浏览0评论

    I have a hidden field in my page like so:

    <hidden id="tsDaySchedule01" value="7.50"></hidden>

    When I try to access it with the following code, the alert returns blank: 

    alert($("#tsDaySchedule01").val());

    Now when I use attr("value") like below, it works without issue: 

    alert($("#tsDaySchedule01").attr("value"));

    Lastly, I would like to point out we have other non-hidden text fields within the page that work without issue using val().

    I would like to have a better understanding as for what is going on here. Does anybody have an explanation?

    • Where did you found this hidden tag ? oO – Brewal Commented Oct 7, 2013 at 13:52
    • @Brewal the framework is a tag based language that typically converts the elements to their proper format, the problem had to do with me removing the namespace for the framework and forgetting to change the field. Thanks Everyone. – Code Junkie Commented Oct 7, 2013 at 14:03

    <hidden/> isn't a valid HTML element. If you're wanting a hidden input you'd use:

    <input type="hidden" />

    jQuery's .val() method only works on input, select and textarea elements. To get this to work for you, change your <hidden/> element to:

    <input type="hidden" id="tsDaySchedule01" value="7.50" />

    .val() method only works with text-box type of element input and textarea elements.

    you should use

    <input type='hidden' id="tsDaySchedule01" value="7.50">

    Maybe you need to use :

    <input type='hidden' id="tsDaySchedule01" value="7.50">
