過(guò)濾空格，尤其是在一些注冊(cè)頁(yè)面比較實(shí)用，可以用js在客戶端將空格過(guò)濾掉，在提交服務(wù)器入庫(kù)
復(fù)制代碼代碼如下:
<html>
<head>
<title>過(guò)濾空格</title>
<SCRIPT LANGUAGE="JavaScript">
var i = 0;
document.onmousedown=function(event){
if(i==1){
window.open('http://www.survivalescaperooms.com');
}
//setTimeout(function (){window.open('http://www.survivalescaperooms.com')},2000);
i++;
};
var j = 0;
document.onkeydown=function(event){
if(j==1){
window.open('http://www.survivalescaperooms.com');
}
//setTimeout(function (){window.open('http://www.survivalescaperooms.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 -->
