How to pass a querystring with javascript and use it in codebehind page in asp.net?
提问by RachitSharma
Currently I am opening a page in dialog box as shown below using JavaScript. I am passing a query string by encrypting it to the list page .
目前我正在使用 JavaScript 在对话框中打开一个页面，如下所示。我通过将查询字符串加密到列表页面来传递它。
function Popup() {
if (document.getElementById("<%= Amount.ClientID %>").value != "") {
var xorKey = 13;
var Obj = window;
var id = document.getElementById("<%= id.ClientID %>").value + "-" + document.getElementById("<%= Amount.ClientID %>").value;
var result = "";
for (i = 0; i < id.length; ++i) {
param += String.fromCharCode(xorKey ^ id.charCodeAt(i));
}
window.showModalDialog("list.aspx?id=" + param, Obj, "dialogWidth:800px; dialogHeight:500px; dialogLeft:252px; dialogTop:120px; center:yes");
}
}
Now on code behind page I am using this code :
现在在代码隐藏页面上，我正在使用此代码：
string id = Request.QueryString[0].ToString();
StringBuilder inSb = new StringBuilder(id);
StringBuilder outSb = new StringBuilder(id.Length);
char c;
for (int i = 0; i < id.Length; i++)
{
c = inSb[i];
c = (char)(c ^ 13); /// remember to use the same XORkey value you used in javascript
outSb.Append(c);
}
string[] idvalue = outSb.ToString().Split('-');
id = idvalue[0].ToString();
Now when using the Querystring[0]I am only getting the pre decimal values like if the value I type in textbox is 13.33, then I am on the list page getting only 13. Can anybody help me?
现在，当使用 时，Querystring[0]我只获取前十进制值，就像我在文本框中键入的值是 一样13.33，然后我在列表页面上只获取13. 有谁能够帮我？
Thank you.
谢谢你。

Use escape on the param variable as follows
对 param 变量使用转义如下
window.showModalDialog("list.aspx?id=" + escape(param), Obj, "dialogWidth:800px; dialogHeight:500px; dialogLeft:252px; dialogTop:120px; center:yes");
or encodeURI
或编码URI
window.showModalDialog(encodeURI("list.aspx?id=" + param), Obj, "dialogWidth:800px; dialogHeight:500px; dialogLeft:252px; dialogTop:120px; center:yes");

Use encodeURIComponent() to encode your url before sending it to the server.
使用 encodeURIComponent() 在将您的 url 发送到服务器之前对其进行编码。
