我想在js函数中把一个字符串去首尾空格怎么去
只用JavaScript能办到吗
[解决办法]
下面比较全吧:
<SCRIPT LANGUAGE="JavaScript"><!--//出处:网上搜集// Trim() , Ltrim() , RTrim()String.prototype.Trim = function(){return this.replace(/(^\s*)|(\s*$)/g, "");}String.prototype.LTrim = function(){return this.replace(/(^\s*)/g, "");}String.prototype.RTrim = function(){return this.replace(/(\s*$)/g, "");}//--></SCRIPT><input type="text" value=" 前后都是空格 " id="space"><input type="button" value="去前后空格" onclick="javascript:document.getElementById('space').value=document.getElementById('space').value.Trim();document.getElementById('space').select();"><input type="button" value="去前空格" onclick="javascript:document.getElementById('space').value=document.getElementById('space').value.LTrim();document.getElementById('space').select();"><input type="button" value="去后空格" onclick="javascript:document.getElementById('space').value=document.getElementById('space').value.RTrim();document.getElementById('space').select();"><input type="button" value="还原" onclick="javascript:document.getElementById('space').value=' 前后都是空格 ';"> 去掉所有的空格 url=game_name.replace(/( )/g,"-").toLowerCase()+"-cd-key-gametime-card.html"
