hidden-field

问题 I have a form and in the form I'm appending hidden values dynamically via JQuery and these hidden values look like this: <input type="hidden" name="times[]" value="{'time': '5:00pm','date': 'april 15th'}" /> <input type="hidden" name="times[]" value="{'time': '6:00pm','date': 'april 16th'}" /> <input type="hidden" name="times[]" value="{'time': '7:00pm','date': 'april 17th'}" /> Using JQuery how can I iterate through the times[] array and output each value so the person can see all the values

问题 I don't understand pretty well how the hidden fields arrays work, I have this input: <input type="hidden" id="ftpIds[]" value=""/> How can I add and remove values to and from that array in Jquery/Javascript? I have something like this: $(document).ready(function() { $('#button').click(function(){ var ids=$("#txtIds").val(); $("#ftpIds").addToArray(ids); }); }); and to remove do I need something like this? $("#ftpIds").removeFromArray('3'); I want to pass a list to a Controller in Grails, so I

问题 How can I access the content of hidden field, where the hiddenfiled's visibility set to Visible=false in the server side using C#. I am not in a situation to use CSS's display:none instead of Visible=false . 回答1: If Visible is false , then the control did not go down to the client, so you cannot directly access it from javascript: it simply isn't there. Equally, since it is a HiddenField (i.e. <input type="hidden"...> ), there is no need to set display:none - it will never be visible, even if

问题 So my question is this: I am doing a foreach loop, and it generates a link list. Each link is having JavaScript in it, which submits the form. I want to, however, attached to EACH link a variable so that I can get the $_POST variable to see WHICH link has been clicked. I tried a foreach loop and then something like: foreach ($matches as $match) { ?> <div class="containerbla"> <form> <h3><a href="javascript:{}" onclick="document.getElementById('matchesform').submit(); return false;"><?php echo

问题 My second question today. I got really stuck. Ok, I have two fields in an aspx file: <input type="text" id="tbName" runat="server"/> <input type="hidden" id="hfName" runat="server"/> The idea is to use text from textbox "tbName" as a parameter for my stored procedure. I decided to add its text to a hidden field "hfName" using javascript: document.getElementById("<%= hfName.ClientID %>").value = document.getElementById("<%= tbName.ClientID %>").value; alert(document.getElementById("<%= hfName

问题 I have a custom webpart that displays report data. It lives inside a tab control, and inside an update panel so the call back to refresh the report data is async. On the server, I need to process some data and send back a value for later use. This variable just needs to SIT there and wait for user action, and then a client side javascript will use read the variable and based on the condition of the variable, this javascript will programmatically "click" the button in the update panel. THE

问题 I am trying to render a list of objects in my controller which are passed from jsp as hidden varaiable. Here is my code in my employeeResults.jsp <c:forEach items="${list}" var="employee" > <tr> <td>${employee.empId}</td> <td>${employee.empName}</td> <td>${employee.empEmail}</td> </tr> </c:forEach> <form method="POST" action="downloadCSV.html" > <input type="hidden" id="empList" name="empList" value="${list}"/> <input type="submit" name="download" value="Download"/> </form> In my Controller /

问题 This may be a basic question... However I've just been picking a solution without giving much though to it... Consider a page with a grid of forms: /FormList.aspx where choosing to edit a form redirects the user to a page like: /FormEdit.aspx?Id=2 I usually am okay with passing the values in the query string, because I check in the code-behind of FormEdit that the Id is valid. Which is the best way to pass the value , though: session or query string ? Or other? While the user is editing the
