循环判断取值

JScript code

            var text1 = document.getElementById("<%=text1.ClientID %>").value;            var text2 = document.getElementById("<%=text2.ClientID %>").value;            var text3 = document.getElementById("<%=text3.ClientID %>").value;            var text4 = document.getElementById("<%=text4.ClientID %>").value;            var text5 = document.getElementById("<%=text5.ClientID %>").value;           var textString = new Array(text1, text2, text3, text4, text5);     for (var i = 0; i < imageString.length; i++) {   //判断textString里是否有值,取出有值的并alert打印出来         }

判断textString里是否有值,取出有值的并alert打印出来
请教下

[解决办法]
for (var i = 0; i < textString.length; i++) {
//判断textString里是否有值,取出有值的并alert打印出来
if(textString[i])
{
alert(textString[i]);
}
}
