javascript 如何在 window.location.href 中传递 QueryString？

Question

提问by Abhay Andhariya

I have written the following javascript function

我编写了以下 javascript 函数

function getval(sel)
 {
    window.location.href = "Posts?Category=<%= sel %>";
 }

but the value of sel variable is not considered in querystring..

但是在查询字符串中不考虑 sel 变量的值..

Instead of it, it takes value like following.

而不是它，它需要像下面这样的值。

...../Post/Posts?Category=%3C%=%20sel%20%%3E

...../帖子/帖子？类别=%3C%=%20sel%20%%3E

Can anyone help me???

谁能帮我？？？

Answer 2

I don't know where you found this <%= sel %>, but its not the native JavaScript style of doing it. Try this:

我不知道你在哪里找到的<%= sel %>，但它不是原生的 JavaScript 风格。试试这个：

function getval(sel)
{
    window.location.href = "Posts?Category=" + sel;
 }

Answer 3

in Posts.html page add the code:

在 Posts.html 页面添加代码：

var queryString = location.search;

var Category = queryString[0];
