Question

我正在使用jQuery Mobile。我有一个切换按钮，当用户点击时我需要启动一个确认对话框。

HTML

<div data-role="fieldcontain"> 
    <div class='ui-grid-a' > 
     <div class='ui-block-a'> 
      <h4 rel='tooltip' title='Feature that automatically solves other values as you type in inputs' style='color:#cc0000;'>Auto-Solve</h4> 
     </div> 
     <div class='ui-block-b'> 
      <select name="togSwitch" id="autosolve" data-theme="" data-role="slider" data-mini="true"> 
       <option value="off">Off</option> 
       <option selected value="on">On</option> 
      </select> 
     </div> 
    </div> 
</div> 

jQuery的

$(document).ready(function() { 
$('#autosolve').toggle(function() { 
    var answer = confirm('This will erase all current values. Are you sure you want to continue?'); 
    if (answer === false) {return;} else {reset();} 
    }, function() { 
    var answer = confirm('This will erase all current values. Are you sure you want to continue?'); 
    if (answer === false) {return;} else {reset();} 
}); 
}); 

我也试着做一个标准的点击功能，但没有奏效：

$('#autosolve').click(function() { 
    var answer = confirm('This will erase all current values. Are you sure you want to continue?'); 
    if (answer === false) { 
     return; 
    } else { 
     reset(); 
    } 
}); 

我也试过.change（），但它启动onload，并且它还在我的切换开关下面显示一个小的选择框，这很奇怪。

有人知道如何正确启动一个确认对话框，一旦用户点击切换开关？并在切换之前更改

以这种方式使用的toggle()函数在jQuery 1.8中被弃用，并在1.9中被删除！您应该可以挂接到built in events的jQ移动切换开关：

$("#autosolve").on('slidestart', function(event) { 
    var answer = confirm('This will erase all current values....'); 
    if (answer) reset(); 
    return answer;  
});
