问题 A bit hard to explain, so I've set up a jsFiddle here. Basically, I have some behaviour triggered when a user clicks a checkbox. In another place I'm trying to programatically click the check box and I need to see the exact same behaviour. It doesn't work, seemingly something to do with the order of the click and determining the checked attribute. How can I get the behaviour I'm looking for without resorting to a hack? 回答1: I tend to use change handler here instead (since jQuery normalizes

问题 Can I use PHP checkbox array with the GET Method? And if there are two checkboxes clicked, will that result in: some.php?param=1&param=2 ? As you know, I am not used to write into database, I'm just getting the parameters. Thanks. 回答1: You need to pass the checkboxes with the same field name followed by [] so PHP recognizes the array. Like so: <input type="checkbox" name="foo[]" value="bar1"> <input type="checkbox" name="foo[]" value="bar2"> <input type="checkbox" name="foo[]" value="bar3">

问题 I need to attach a function to a checkbox so that clicking it does nothing. How is this possible? I don't want it to be greyed out, I just want to stop it from being togglable. 回答1: If you want it to be toggleable, just attach an event listener as follows: $('#checkboxId').on('click', function(e) { e.preventDefault(); e.stopPropagation(); }); Note: This is the same effect as returning false : $('#checkboxId').on('click', function(e) { return false; }); 回答2: Try something like this: <input

问题 I kind of have a 2 part question here. 1) How can I populate my ListView so that strings are what is displayed, but when items are selected, a non-visible id value (contact id from phone contacts) is the value that is actually used? 2) I have a ListView that's using multipleChoice mode for item selections. It's popluated with names from my contacts list. When I select an item in the ListView, I want that selected item to trigger a call to my SqLite routine to store the value into a database

问题 I've got long labels for a couple checkboxfields in my app, and unfortunately it causes some strange behavior. Is there any way to make this look a little better? I mean, if I 'touch' the gray area, the checkbox does not activate (even if the checkbox is inside the gray area)... but instead I have to click the white area. It's just kinda confusing. Even if I set labelWidth: '80%' to each checkboxfield , the words still wrap and show that little gray area. I'd rather that area be all white and

问题 I'm learning QtQuick and I'm playing with data binding between C++ classes and QML properties. In my C++ object Model, I have two properties : Q_PROPERTY(QString name READ getName WRITE setName NOTIFY nameChanged) Q_PROPERTY(bool status READ getStatus WRITE setStatus NOTIFY statusChanged) And in my .qml file : TextEdit { placeholderText: "Enter your name" text: user.name } Checkbox { checked: user.status } When I change the user name with setName from my C++ code, it is automatically
