checkbox

问题 I am dealing with a dynamic form that can potentially provide the user with an unspecified number of checkboxes in an array (category[]). This causes a few issues. Issue #1 : Hitting the maximum number of POST variables that the browser and/or server allows. This can be solved by using a bit of script and actually posting the array in a single comma separated value. Issue #2 : Browsers getting very slow and / or crashing. One user has over 5000 checkboxes representing categories, which causes

问题 I am trying to change the squirrelmail GUI so it can be used with tablets more easily. I have pretty much sorted everything, except i have a checkbox inside an <a> tag that i dont want to open link when checkbox is clicked. It is all inside a <li> so that the whole line can be clicked on to open the mail under the cursor. Below is the code, and here is a link to what i have so far, which works for what i want to do except for the checkbox: http://jsfiddle.net/YEpuf/1/ <li> <a href="read_body

问题 I know my PHP but I got only very basic JavaScript knowledge, probably because I try to avoid to use JavaScript at all because there is always the risk of visitors having disabled JavaScript's in their browsers... However now I need a certain task in a html form that might only be solved by using JavaScript. I have one textarea and one checkbox. The checkbox is checked by default when the page is loaded. I want the checkbox to become unchecked automatically if the user clicks inside the

问题 I have a layout which contains a TextView and a CheckBox, and this looks as expected on my Galaxy Nexus (4.2.2): However when viewing on a Galaxy S3 and S2, I get some odd padding to the top, right and bottom of the CheckBox which is messing up the horizontal alignment of the whole subview: The XML layout: <?xml version="1.0" encoding="UTF-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ll_vert" android:layout_width="match_parent" android:layout

问题 I'm trying to create a checklist but only the first checkbox is working. When I click on the other ones it checks the first box. Also, I added "text-decoration: line-through;" but it's not showing up in the text. I'm pretty sure I can fix that with HTML though. http://codepen.io/tyl-er/pen/kXmkqB?editors=0100 Here's my code: <div class="box"> <input type='checkbox' name='thing' value='valuable' id="thing"/><label for="thing"></label> get an army <br> <input type='checkbox' name='thing' value=

问题 I am trying to display a text when the user selects the input tag, For example, I have the following code: <tr> <td class="align"> Yes <br/> <input type="checkbox" /> </td> </tr> Once the user clicks on the check box, the following text will appear: "If you have selected yes,....." And I am not sure if JavaScript would be the best path to do this. But , If it is, would it be something like: <script> $(function(){ if(input was checked)//not sure what would go here, new to Javascript display

问题 I don't know. Simply I don't know. Why does the second codeblock work and check the checkboxes by default, but the first block isn't? I need to pre-check bitmask flags and I can't/don't want to append strings or something. // THIS isn't working?!! $test1 = array( 2 => 'tomato', 4 => 'bitmask problem' ); $test2 = array(2, 4); $form->addElement('multiCheckbox', 'flags', array( 'label' => 'Flags', 'value' => $test2, 'multiOptions' => $test1, ) ); // THIS IS WORKING: $form->addElement (

问题 I have got a checkbox list populated from database , I want to get the ID of each checkbox list during post action so that I can save that in the db , Below is the Code : Controller: public ActionResult Create() { ITrackdayRepository trackdayResp = new TrackdayRepository(); IQueryable<Object> getAllEvents = trackdayResp.GetEventsSelectlist(); var m = new SelectList(getAllEvents,"ID","Name"); ViewData["events"] = new SelectList(getAllEvents.ToList(), "EventID","Date"); return View(); } // //

问题 I have a ASP.Net web page that includes a nested GridView. Within the nested GridView is a template field with a CheckBox.
