我正在制作一个Web应用程序，但我在努力替换页面。在函数myPage()中，当我将location.replace("file.html");放在开头时，如果我没有在Web应用程序中插入inputs，则可以使用，但是当我将location.replace("file.html");放入if语句中时，根本不起作用，我需要在location.replace的位置放置。
请帮助我。
js代码：
var submit = document.getElementById("submit");
submit.addEventListener("click",myPage);
function myPage(){
//location.replace("file.html"); // here this is working
var name=document.formId.nameRadio.value;//name="abc"
if (name=="abc"){
location.replace("file.html");//but here not
}
}
html代码：
<form id="formId" name="formId" >
<label>sth </label><br><br>
<label for="name"> name </label>
<input type="text" id="name" name="name" required>
<fieldset>
<legend>sth</legend>
<ul class="class-radio" >
<li> <input type="radio" name="nameRadio" id="abc" value="abc" required><label for="abc">abc</label></li>
<li> <input type="radio" name="nameRadio" id="cdf" value="cdf"><label for="cdf">cdf</label></li>
</ul>
</fieldset>
<input id="submit" type="submit" value="next" >
</form>
var submit = document.getElementById("submit");
submit.addEventListener("click", myPage);
function myPage(e) {
//prevent form submission
e.preventDefault();
var name = document.getElementById('formId').nameRadio.value;
if (name == "abc") {
location.replace("file.html");
}
}<form id="formId" name="formId">
<label>sth </label><br><br>
<label for="name"> name </label>
<input type="text" id="name" name="name" required>
<fieldset>
<legend>sth</legend>
<ul class="class-radio">
<li> <input type="radio" name="nameRadio" id="abc" value="abc" required><label for="abc">abc</label></li>
<li> <input type="radio" name="nameRadio" id="cdf" value="cdf"><label for="cdf">cdf</label></li>
</ul>
</fieldset>
<input id="submit" type="submit" value="next">
</form>将按钮类型更改为按钮。您的浏览器首先提交。
var submit = document.getElementById("submit");
submit.addEventListener("click",myPage);
function myPage(){
//location.replace("file.html"); // here this is working
var name=document.formId.nameRadio.value;//name="abc"
alert(name);
if (name=="abc"){
location.replace("file.html");//but here not
}
}<form id="formId" name="formId" >
<label>sth </label><br><br>
<label for="name"> name </label>
<input type="text" id="name" name="name" required>
<fieldset>
<legend>sth</legend>
<ul class="class-radio" >
<li> <input type="radio" name="nameRadio" id="abc" value="abc" required><label for="abc">abc</label></li>
<li> <input type="radio" name="nameRadio" id="cdf" value="cdf"><label for="cdf">cdf</label></li>
</ul>
</fieldset>
<input id="submit" type="button" value="next" >
</form>似乎您想对表单提交进行更多控制。您可以将输入类型从“提交”更改为“按钮”。还要重命名该按钮以避免confusion with submit method of the form。您还可以通过直接在输入上使用click事件来简化代码。您可以尝试以下方法：
<html>
<body>
<form id="formId" name="formId">
<label>sth</label><br><br>
<label for="name">name</label>
<input type="text" id="name" name="name" required>
<fieldset>
<legend>sth</legend>
<ul class="class-radio">
<li><input type="radio" name="nameRadio" id="abc" value="abc" required><label for="abc">abc</label></li>
<li><input type="radio" name="nameRadio" id="cdf" value="cdf"><label for="cdf">cdf</label></li>
</ul>
</fieldset>
<input id="btnSubmit" type="button" value="next" onclick="mySubmit()">
</form>
<script>
function mySubmit()
{
var name = document.formId.nameRadio.value;
if (name == "abc"){
location.replace("file.html");
} else {
// Submit a form
document.formId.submit();
}
}
</script>
</body>
</html>
