我有一个很大的形式，我必须验证44个字段。我使用javascript表单验证来要求字段输入，并使用C＃正则表达式来确保有效输入。我不会详细说明为什么我必须这样做，但这是如何运作的。我已经对此代码块进行了三重检查，我必须验证表单并且无法找到错误。代码低于（大），希望有人比我更好的眼睛。
C＃
@using (Html.BeginForm("Create", "Table1_1", FormMethod.Post, new { onsubmit = "return validateit()", name = "myForm" }))

注意：此代码适用于我的所有其他视图。我必须在某个地方打个错字，但我似乎无法找到它。谢谢！
答案 0 :(得分：0)
x27检查分配给null而不是测试null：
if (x27 = null || x27 == "" || x27 == " ") {
应该是
if (x27 == null || x27 == "" || x27 == " ") {
如果你确实需要这个功能，你可能会发现这样的东西更容易使用：
function validateit() {
var fields = [
["COMPANY1", "Company number is required"],
["STATE1", "State code is required"],
["BILL_CODE1", "BILL_CODE1 is required"],
["EFFECTIVE_DATE1", "EFFECTIVE_DATE1 is required"],
["RECORD_TYPE1", "RECORD_TYPE1 is required"],
// ...
];
var count = 0;
for (var i = 0; i < fields.length; i++) {
var x = document.forms.myForm[fields[i][0]].value;
if (x === null || x === "" || x === " ") {
count++;
document.getElementById("demo" + (i + 1)).innerHTML = "<font style='color:red';>Error: " + fields[i][1] + "</font>";
}
else {
document.getElementById("demo" + (i + 1)).innerHTML = "";
}
}
}
