  • How to get password html helper to render password on failed validation

    - by Max Schmeling
    I have a form for creating a new account and it has a password field in it. I'm using view models to pass data to the controller action and back to the form view. When the user enters their details in, and clicks submit, if validation fails and it returns them to the same view passing back in the view model, it won't default the password to what they entered. How can I get it to do this? Or should I even try?

  • Can't get jQuery to get focus on cloned input fields

    - by Rebel1Moon
    I have a page that needs to create dynamic form fields as often as the user needs, and I am trying to use Ajax to tie it in to my database for faster form entry and to prevent user typos. So, I have put my Ajax returned data into popup div, the user selects, then the form field is filled in. The problem comes on the cloned fields. They don't seem to want to bring up the popup div when focused. I am thinking it is something to do with when they get created/added to the DOM. Here is my JS that creates the clones: $(document).ready(function() { var regex = /^(.*)(\d)+$/i; var cloneIndex = $(".clonedInput").length; $("button.clone").live("click", function(){ $(this).parents(".clonedInput").clone() .appendTo("#course_container") .attr("id", "clonedInput" + cloneIndex) .find("*").each(function() { var id = this.id || ""; var match = id.match(regex) || []; if (match.length == 3) { this.id = match[1] + (cloneIndex); } }); cloneIndex++; numClones=cloneIndex-1; //alert("numClones "+numClones); }); Here is where I expect to be able to get focus on the correct cloned field and call the popup. The baker_equiv0 id is original code, whereas baker_equiv1 is the first clone. $('#baker_equiv0').focus(function() { \\ THIS CODE WORKS $('.popup').fadeIn(500); $('#results').empty(); // document.enter_data.baker_equiv1.value="test"; THIS LINE WORKS //alert("numClones "+numClones); }); $('#baker_equiv1').focus(function() { // THIS DOESN'T EVER FIRE alert("numClones "+numClones); $('.popup').fadeIn(500); $('#results').empty(); }); Here is the HTML with the form: <label for="baker_equiv" class="">Baker Equivalent: <span class="requiredField">*</span></label> <input type="text" class="cinputsa" name="baker_equiv[]" id="baker_equiv0" size="8" ONKEYUP="get_equiv(this.value);"> If I put this in the HTML code above, it works fine: onfocus="alert(this.id)" I'd also be interested in how to adjust the JS code to work based on the id array created rather than having to copy code for each potential set of fields clones, i.e., baker_equiv[] rather than baker_equiv0, baker_equiv1, etc. Thanks all!

  • show div for a set time, then hide it

    - by Patrick
    Im using jquery for various things on my site, but one thing im not sure how to do, is have it show an element, then wait X seconds, and hide the element. $('#form').ajaxForm(function() { $('#cartcontents').fadeOut("fast").load('cart.php').fadeIn("fast"); }); That's the JavaScript that I'm using now. How could I have it (when the form submits) display the div #notice for 5 seconds, then fadeOut?

  • A file is being http posted, how can I reference the parameter by index?

    - by Blankman
    An XML file is being posted to a url that my spring mvc is responding to. In .NET, I could do this: request.Form[0] request.Form["abc"] or request.QueryString[0] request.QueryString["some_key"] Now with spring/servlets it seems I can only do this: request.getParameter("some_key") or get all the names or values. When someone is posting a file to a url, using http post, won't this be just a single request parameter then? Can I get the parameter using index with servlets?

  • is the jQuery function "change()" working in IE ?

    - by Patrick
    is the jQuery function "change()" working in IE ? I usually use it to detect changes in forms (select/unselect check boxes), and submit them automatically without having to click on submit button (which is hided). i.e. $("#views-exposed-form-Portfolio-page-1").change(function(){ $("#views-exposed-form-Portfolio-page-1").submit(); }); But in Ie it doesn't work. It seems I have to use "click" instead. thanks
