Question

我正在尝试验证表单，但是当我按下提交按钮时，它没有做任何事情......我想让它发送到下一页是game.html。

HTML：

<!--[if IEMobile]>
<link rel="stylesheet" type="text/css"
href="/styles/mobile.css" media="screen"/>
<![end if]-->

的Javascript

// JavaScript Document
var $ = function(id) { return document.getElementById(id); }

function validateForm(){
    var nextPage = true;
    var regFName = /^([A-Z])[a-z]{1,20}$/;
    var regLName = /^([A-Z])[a-z]{1,30}$/;
    var regPnum = /^\d{3}\-\d{3}\-\d{4}$/;
    var regPostCode = /^[A-Za-z]{1}\d{1}[A-Za-z]{1} \ *\d{1}[A-Za-z]{1}\d{1}$/;
    var myMoney = $("startMoney").value;
    var regMoney = /[\.\,]/;
    document.fback.postCode.value = document.fback.postCode.value.toUpperCase();

    if ($("fname").value == "")
    {
        alert ("Enter your first name");
        nextPage = false;
    }

    else if (!$("fname").value.match(regFName))
    {
        alert ("You must capitalize your first character, and then the rest are lower-case. Only letters allowed. E.G: Charlie");
        nextPage = false;
    }

    else if ($("lname").value == "")
    {
        alert ("Enter your last name");
        nextPage = false;
    }

    else if (!$("lname").value.match(regLName))
    {
        alert ("You must capitalize your first character, and then the rest are lower-case. Only letters allowed. E.G: Kaing");
        nextPage = false;
    }

    else if ($("pnum").value == "")
    {
        alert ("Enter your phone number");
        nextPage = false;
    }

    else if (!$("pnum").value.match(regPnum))
    {
        alert ("You must use numbers only. Enter your phone in the following format: ###-###-#### E.G: 613-600-6991");
        nextPage = false;
    }

    else if ($("postCode").value == "")
    {
        alert ("Enter your postal code");
        nextPage = false;
    }

    else if (!$("postCode").value.match(regPostCode))
    {
        alert ("Enter your postal code in the following format: ANA NAN");
        nextPage = false;
    }

    else if ($("startMoney").value == "")
    {
        alert ("Enter your starting amount of money");
        nextPage = false;
    }

    else if (isNaN(myMoney) || parseInt(myMoney) < 5 || parseInt(myMoney) > 5000 || $("startMoney").value.match(regMoney))
    {
        alert ("You must enter money between 5$ and $5000. Only numbers allowed. No cents. E.G: 5000");
        nextPage = false;
    }
    nextPage = true;
}

Answer 1

你的函数没有返回任何内容，并且@fizz声明你的输入类型应该是type =＆＃34;提交＆＃34;而不是＆＃34;按钮＆＃34;。

...
else if (isNaN(myMoney) || parseInt(myMoney) < 5 || parseInt(myMoney) > 5000 || $("startMoney").value.match(regMoney))
{
alert ("You must enter money between 5$ and $5000. Only numbers allowed. No cents. E.G: 5000");
nextPage = false;

}
return nextPage;
}

Answer 2

在jquery中访问元素语法的id是$（“＃elementID”），并且通过使用val（）fn来获取元素的值。

离。

   if ($("#fname").val() == "")
{
    alert ("Enter your first name");
    nextPage = false;
}

var myMoney = $("#startMoney").value;

我的javascript表单验证不起作用
