提问by LouisPL
I have a method that returns an array (string[]) and I'm trying to pass this array of strings into an Action.Currently I can't pass my parameters. I am new in MVC3.
Pls let me know why I can't pass parameter to ActionResult..I already define ActionResult with Same parameter name..
thanks all in advance....
我有一个返回数组 ( string[])的方法，我正在尝试将此字符串数组传递给 Action。目前我无法传递我的参数。我是 MVC3 的新手。请让我知道为什么我不能将参数传递给 ActionResult ..我已经定义了具有相同参数名称的 ActionResult .. 提前感谢...
$('#export-button').click(function () {
var columnLength = $("#grid")[0].p.colNames.length;
var columnNames = "";
for (var i = 0; i < columnLength; i++) {
if ($("#grid")[0].p.colModel[i].hidden == false) {
columnNames = columnNames + $("#grid")[0].p.colModel[i].name + ',';
}
}
var Val1 = jQuery(txt_search1).val();
alert(Val1); alert(columnNames);
document.location = '@Url.Action("OrgDataExport","Search", new { Val1 = Val1 , columnNames = columnNames})';
});

Try this,
试试这个，
$('#export-button').click(function () {
var columnLength = $("#grid")[0].p.colNames.length;
// columnNames is an object now
var columnNames = {};
for (var i = 0; i < columnLength; i++) {
if ($("#grid")[0].p.colModel[i].hidden == false) {
columnNames[i] = $("#grid")[0].p.colModel[i].name;
}
}
var Val1 = jQuery(txt_search1).val();
document.location = "Home/Index/" + $.param({ Val1 = Val1 , columnNames = columnNames });
});
Your action that takes columnNamesas a string array
您columnNames作为字符串数组的操作
public ActionResult Index(string val1, string[] columnNames)
{
// Your code
}
UPDATE:
更新：
If the URL becomes too big you can submit the values through form using POST method. If your view already have a form use that else create a dynamic one on the fly and submit the values through POST.
如果 URL 变得太大，您可以使用 POST 方法通过表单提交值。如果您的视图已经有一个表单，请使用它动态创建一个动态表单并通过 POST 提交值。
$('#export-button').click(function () {
var Val1 = jQuery(txt_search1).val();
$("#hidden-form").remove();
// create a form dynamically
var form = $('<form>')
.attr({ id: "hidden-form",
action: "/Home/Index",
method: "post",
style: "display: none;"
})
.appendTo("body");
// add the "Val1" as hidden field to the form.
$('<input>').attr({ name: "Val1 ", value: Val1, type: "hidden" }).appendTo(form);
var columnLength = $("#grid")[0].p.colNames.length;
// add the "columnNames" as hidden fields to the form
for (var i = 0; i < columnLength; i++) {
if ($("#grid")[0].p.colModel[i].hidden == false) {
var t = $("#grid")[0].p.colModel[i].name;
$('<input>').attr({ name: "columnNames", value: t, type: "hidden"
}).appendTo(form);
}
};
// submit the form
form.submit();
});

Hi Louis,
嗨，路易斯，
Your are trying to access javascript varaibles Val1 and columnNames from the server side tag and it is not possible. For more details, please refer this URL.
您正在尝试从服务器端标记访问 javascript 变量 Val1 和 columnNames，但这是不可能的。有关详细信息，请参阅此URL。
You can do it by following way.
您可以通过以下方式进行。
var jsonData = { val1 : Val1, columnNames : columnNames };
$.ajax({
type: "GET", //GET or POST or PUT or DELETE verb
url: "Home/Index", // Location of the service
data: jsonData,
contentType: "application/json; charset=utf-8", // content type sent to server
processdata: true, //True or False
success: function () {
alert("success")
}
});
On your controller side you have to write like
在您的控制器方面，您必须像这样写
public ActionResult Index(string val1, string columnNames)
{
// Your code
}

You tagged JQuery-Ajax but i don't see any ajax attempt in the code example? So i am guessing you want to know an Ajax orientated solution. You're probably not using Zend Framework, but i hope this answers helps point you in the right direction to a solution.
您标记了 JQuery-Ajax，但我在代码示例中没有看到任何 ajax 尝试？所以我猜你想知道一个面向 Ajax 的解决方案。您可能没有使用 Zend Framework，但我希望这些答案有助于为您指明解决方案的正确方向。
From JS/Zend framework experience you could look at something like
根据 JS/Zend 框架经验，您可以查看类似的内容
$('#export-button').click(function () {
....
var actionUrl= "/controller/action/";
$.ajax({
url: actionUrl,
data: {
variable1: "OrgDataExport",
variable2: "Search",
Val1: Val1,
columnNames: columnNames
},
dataType: "json",
success: function(json) {
//do stuff
}
});
....
});
In the ZendFramework controller you can then grab the variables on the request:
在 ZendFramework 控制器中，您可以获取请求中的变量：
$Val1 = $this->_request->getparam("Val1");
