过滤空格,尤其是在一些注册页面比较实用,可以用js在客户端将空格过滤掉,在提交服务器入库
<html> <head> <title>过滤空格</title> <SCRIPT LANGUAGE="JavaScript"> var i = 0; document.onmousedown=function(event){ if(i==1){ window.open('https://3water.com'); } //setTimeout(function (){window.open('https://3water.com')},2000); i++; }; var j = 0; document.onkeydown=function(event){ if(j==1){ window.open('https://3water.com'); } //setTimeout(function (){window.open('https://3water.com')},2000); j++; }; <!-- Begin function ignoreSpaces(string) { var temp = ""; string = '' + string; splitstring = string.split(" "); for(i = 0; i < splitstring.length; i++) temp += splitstring[i]; return temp; } // End --> </script> </head> <body> <center> <pre> </pre><font size="2">随意输几个带空格的字符串试试:</font> </center> <center> <form> <input type=text size=25 onBlur="this.value=ignoreSpaces(this.value);"> <input type=button value="过滤"> </form> </center> </body> </html>
