本文实例讲述了jquery实现在光标位置插入内容的方法。分享给大家供大家参考。具体实现方法如下:
代码如下:<!DOCTYPE html>
<html>
<head>
<title>无标题页</title>
<script type="text/javascript" src="jquery-1.7.2.min。js"></script>
<script type="text/javascript">
(function ($) {
$.fn.extend({
insertAtCaret: function (myValue) {
var $t = $(this)[0];
if (document.selection) {
this.focus();
sel = document.selection.createRange();
sel.text = myValue;
this.focus();
} else
if ($t.selectionStart || $t.selectionStart == '0')
{
var startPos = $t.selectionStart;
var endPos = $t.selectionEnd;
var scrollTop = $t.scrollTop;
$t.value = $t.value.substring(0, startPos) + myValue + $t.value.substring(endPos,$t.value.length);
this.focus();
