推荐答案

您可以使用JavaScript检测游标类型

You can detect the cursor type using JavaScript

like

<input id="sample_text" name="one" type="text" value="Sample Text" />

，JavaScript代码应如下所示：

and the JavaScript code should look something like this

$('input[id=sample_text]').click( function() {
   alert("test");   
   var ctl = document.getElementById('sample_text');
   var startPos = ctl.selectionStart;
   var endPos = ctl.selectionEnd;
   alert(startPos + ", " + endPos);
});

function detect_cursor() {
   alert("test");   
   var ctl = document.getElementById('sample_text');
