在html标记中将文本框值作为查询字符串传递 [英] pass textbox value as querystring in html a tag
问题描述
我正在建立一个asp.net网站。我是这个IT世界的新手。
我有一个列表视图，其中包含一个图像和一个类别的标签。我将这些项目包装在 标记中，这样每当用户点击其中任何一个控件时，它都会重定向到另一个页面。在列表视图之外，我有一个包含城市名称的ajax组合框。它在页面加载时有一个选定的值。
现在，只要用户点击列表视图中的任何一个图像或标签，它就会重定向到包含城市和类别名称的查询字符串值的SubCat.aspx页面。 />
此查询字符串将在a href =页面中传递？查询字符串
我的问题是我无法获得aspx页面中标记中的组合框值。我知道如何从代码后面传递查询字符串。
或者无论如何都要将查询字符串的值放在aspx.cs页面中然后检索它在aspx页面的a标签中？
谢谢。

I have a list view which contains a image and a label of the Category. I am wrapped these items in tag, so that whenever the user click in any of these controls it will redirect to another page. Outside the list view i have an ajax combo box which contains city names. It has a selected value on page load.
Now whenever a user clicks on either image or label inside list view it will redirect to page SubCat.aspx with query string values containing city and category name.
This query string will be passed in "a href="page?query string""
My problem is that i am not able to get the combo box value in a tag in aspx page. I know how to pass query string from code behind.
or is there anyway to put the values of querystring or form the query string in aspx.cs page and then retrieve it in "a" tag in aspx page?
Thank you.
code of aspx:
<head>
<script>
$( document ).ready(function() {
var _cityId = $('#ComboBox1').val();
var url = "http://google.com?cityid=" + _cityId;
$( "span" ).on( "click", function() {
window.location.href = url;
});
});
</script>
