验证特殊字符

school = document.getElementById("school").value;

//验证数据
var CheckData = /<|>|'|;|&|#|"|'/;

if (CheckData.test(school)) {
alert("学校名称不能含有特殊字符");
}

//验证特殊字符串的方法
function validation(str){ //str被验证的字符串
var a = new Array("$", "@", "#","!","~","`","^","&","*","(",")","-","=","_","+","",":","/"","']//","/","?",".",";","{","}","[","]",":","/"","'") //a为验证字符串的规则

for (i = 0; i < a.length; i++) {
if (str.indexOf(a[i]) >= 0) { //此处进行验证判断是否存在指定的字符
return true; //返回值
}
