jQuery：有没有办法将'点击'事件变成双击？

Question

如何使用jQuery来检测click事件为双击？基本上，我希望.select类中的文本更易于选择，以便用户可以快速将内容复制到剪贴板。

<li> 
    <span> 
     Don't Select me 
    </span> 
    <span> 
     Don't Select me 
    </span> 
    <span class="select"> 
     Select Me on click! 
    </span> 
</li>

试试这个

function SelectText(element) { 
    var doc = document; 
    var text = doc.getElementById(element);  
    if (doc.body.createTextRange) { 
     var range = document.body.createTextRange(); 
     range.moveToElementText(text); 
     range.select(); 
    } else if (window.getSelection) { 
     var selection = window.getSelection();   
     var range = document.createRange(); 
     range.selectNodeContents(text); 
     selection.removeAllRanges(); 
     selection.addRange(range); 
    } 
} 

$(function() { 
    $('.select').click(function() { 
     SelectText('selectme'); 
    }); 
});​

更新：

选择相同的点击的元素的含量：

function SelectText(element) { 
    var doc = document; 
    var text = element;  
    if (doc.body.createTextRange) { 
     var range = document.body.createTextRange(); 
     range.moveToElementText(text); 
     range.select(); 
    } else if (window.getSelection) { 
     var selection = window.getSelection();   
     var range = document.createRange(); 
     range.selectNodeContents(text); 
     selection.removeAllRanges(); 
     selection.addRange(range); 
    } 
} 

$(function() { 
    $('.select').click(function() { 
     SelectText($(this)[0]); //Brackets are more efficiently that .get(0) method 
    }); 
});​
