提交表单后如何重定向到另一个HTML页面？

Question

我有一个包含表单元素的HTML页面。 表单包含单选类型的输入和最后一个按钮。 我想要单击按钮时调用一个javascript方法，该方法获取选定选项的值并重定向到selectedChoice.html页面。

这是我的HTML页面。

<html>
    <head>
        <script type="application/javascript" src="../js/navigation.js"></script>

    </head>
    <body>
        <div id="chooseBodyPart">
            <form>
                <div class="question-text">
                    <p>Which body part is at dis-ease??</p>
                </div>
                <input class="radio-option" type="radio" name="bodyPartAtDisease" value="chest"> Chest <br>
                <input class="radio-option" type="radio" name="bodyPartAtDisease" value="head"> Head <br>
                <input class="radio-option" type="radio" name="bodyPartAtDisease" value="shoulders"> Shoulders <br>
                <input class="radio-option" type="radio" name="bodyPartAtDisease" value="eyes"> Eyes <br>
                <input class="radio-option" type="radio" name="bodyPartAtDisease" value="ears"> Ears <br>
                <input class="radio-option" type="radio" name="bodyPartAtDisease" value="heart"> Heart <br>
                <button onclick="redirectToNextPageBasedOnResponse();">Proceed</button>
            </form>



        </div>
    </body>
</html>

下面是我的js。

function getListOfChoices(form) {
    var choices = form.getElementsByTagName("input");
    return choices;
}


// list of choices should be passed to this method and name of checked choice should be returned.
// In case no choice is selected the return null
function getNameOfCheckedChoice(choices) {
    var selectedChoice = null;
    for (var choiceNumber = 0; choiceNumber < choices.length; choiceNumber++) {
        if (choices[choiceNumber].checked) {
            selectedChoice = choices[choiceNumber].value;
            break;
        }
    }
    return selectedChoice;
}


function redirectToNextPageBasedOnResponse() {
    var divContainingForm = document.getElementById("chooseBodyPart");
    var form = divContainingForm.getElementsByTagName("form")[0];
    var choices = getListOfChoices(form);
    var selectedChoice = getNameOfCheckedChoice(choices);

    window.location.href = "http://" + window.location.host + "/html/" + selectedChoice + ".html";
}

代码的工作完全符合我的要求，但是一旦控件从redirectToNextPageBasedOnResponse（）返回，URL不会更改为我编写的代码，而是将查询参数插入到现有URL中，其值等于所选选项。

有人可以解释发生了什么吗？

欢迎使用Stack Overflow！

请检查

window.location=url

要么

history.pushState({}, "title", url);

代替。

您只缺少一件事。 在submit事件上调用preventDefault() 。

您需要通过onclick="redirectToNextPageBasedOnResponse(event);" 然后在您的处理程序中，执行event.preventDefault() 。

 function getListOfChoices(form) { var choices = form.getElementsByTagName("input"); return choices; } // list of choices should be passed to this method and name of checked choice should be returned. // In case no choice is selected the return null function getNameOfCheckedChoice(choices) { var selectedChoice = null; for (var choiceNumber = 0; choiceNumber < choices.length; choiceNumber++) { if (choices[choiceNumber].checked) { selectedChoice = choices[choiceNumber].value; break; } } return selectedChoice; } function redirectToNextPageBasedOnResponse(event) { event.preventDefault(); var divContainingForm = document.getElementById("chooseBodyPart"); var form = divContainingForm.getElementsByTagName("form")[0]; var choices = getListOfChoices(form); var selectedChoice = getNameOfCheckedChoice(choices); window.location.href = "http://" + window.location.host + "/html/" + selectedChoice + ".html"; }

 <div id="chooseBodyPart"> <form> <div class="question-text"> <p>Which body part is at dis-ease??</p> </div> <input class="radio-option" type="radio" name="bodyPartAtDisease" value="chest"> Chest <br> <input class="radio-option" type="radio" name="bodyPartAtDisease" value="head"> Head <br> <input class="radio-option" type="radio" name="bodyPartAtDisease" value="shoulders"> Shoulders <br> <input class="radio-option" type="radio" name="bodyPartAtDisease" value="eyes"> Eyes <br> <input class="radio-option" type="radio" name="bodyPartAtDisease" value="ears"> Ears <br> <input class="radio-option" type="radio" name="bodyPartAtDisease" value="heart"> Heart <br> <button onclick="redirectToNextPageBasedOnResponse(event);">Proceed</button> </form> </div>

因此，我们阻止了表单提交的默认行为，并为其添加了自定义行为。
