Jquery 获得输入div光标的位置
在网上找了个IE里 JavaScript 的实现方法 ，但是 火狐谷歌等浏览器不行啊，我是想 Jquery 能不能实现呢？大家帮忙看一下，下面是 JavaScript 的实现方法：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title> new document </title> </head> <body> <div contentEditable="true" style="height:50px; border:2px solid red;"></div> 光标前的字符：<span id="selection"></span> <script language="javascript"> <!-- var cursor = 0;// 光标位置 document.onselectionchange = function() { var range = document.selection.createRange(); var srcele = range.parentElement(); var copy = document.body.createTextRange(); copy.moveToElementText(srcele); for (cursor = 0; copy.compareEndPoints("StartToStart", range) < 0; cursor++) { copy.moveStart("character", 1); } document.getElementById("selection").innerText = srcele.innerText.substring(cursor - 1, cursor); } //--> </script> </body> </html> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>java Test</title> </head> <style type="text/css"> <!-- body,div { margin:0; padding:0;} --> </style> <script type="text/javascript" src="js/jquery.js"></script> <body> <div style="background:#ccc;height:300px;" onclick=""></div> <div style="position:relative;"> <div style=" position:absolute;left:50px; top:50px;" id="DivID"></div> </div> <script type="text/javascript"> var X = $('#DivID').offset().top; var Y = $('#DivID').offset().left; document.write(X+"<br />"); document.write(Y+"<br />"); //获取相对(父元素)位置: var C = $('#DivID').position().top; var D = $('#DivID').position().left; document.write(C+"<br />"); document.write(D); </script> </body> </html>
