I am very new to web development (about a month) and i have run into something strange.
I am using VS2010, MVC 3 Razor to create a simple app.
I have two tables holding the same type of information. As in both table A and Table B hold users. the Difference being, Table A has users who are in the "Role", and table B holds the users who are not in the "Role".
Both tables have two columns, One with the user name, the other holds a Ajax.ActionLink.
So, to add a user to Table "B", I click the "Ajax.Actionlink" on Table "A". The "add" is save through the MVC action, and i move the Table Row using AjaxOption OnSuccess event. The OnSuccess event basically, moves the Row, and alters the Ajax.ActionLink so the newly added User row's ActionLink will Remove the User.
I hope that's clear.
This all works fine. I can add user "A" to the table "A" and everything works fine. I can remove user "A" from table "A" to table "B" and everything is fine. But I can not re-add User A to table "A". The OnSuccess runs, so the row is move, but the Action event is not called. So if i refresh the screen i can see the move did not actually take place. it is the same if i start with User "B" on table "B". Also, a page refresh (F5) does not fix the links, the remain broken until i close and reopen the page.
Everything looks good in the HTML, it shows in the status bar that when i click the link, the correct href is being called, but fiddler registers no call and the action is not called.
I suspect i have some sort of binding issues, but i am lost here. Everything works fine in Firefox
Please help. Code below, with Comments added. Remember this works to add and remove, remove and add, but re-add and re-remove only calls the function but does not call the Action. So i know the Actions are spelt correctly etc.
//// element is the ID of the element i am Moving
//// targetElement is the ID of the tbody i am moving the element to
function move_element(element, targetElement) {
try
{
//// get the HTM
var elementHTML = $("tr[id=" + element + "]").children(".Action").html();
//// based on the tbody id
switch (targetElement)
{
case "AssignedToGroup":
//// Change the target body for next call to this function
elementHTML = elementHTML.replace("AssignedToGroup", "UnassignedToGroup");
//// change th action name
elementHTML = elementHTML.replace("AddGroupRole", "DeleteGroupRole");
//// change the display label
elementHTML = elementHTML.replace("Assign", "Remove");
break;
case "UnassignedToGroup":
elementHTML = elementHTML.replace("UnassignedToGroup", "AssignedToGroup");
elementHTML = elementHTML.replace("DeleteGroupRole", "AddGroupRole");
elementHTML = elementHTML.replace("Remove", "Assign");
break;
}
//// Create the new Ajax <td> element
$("tr[id=" + element + "]").children(".Action").replaceWith("<td class='Action'>" + elementHTML + "</td>")
//// Add the row to the other body
$("tr[id=" + element + "]").appendTo($("tbody[id=" + targetElement + "]开发者_StackOverflow社区"));
}
catch (e)
{
alert(e.Message); ////NO ERROR IS RAISED
}
}
I was looking at a similar issue you have had and found a solution here: Cache issue with Ajax.ActionLinks To summarize:
- One suggestion was to call this:
$.ajaxSetup({ cache: false });
If you are using unobtrusive javascript support for jquery. - Another suggestion was to use
"HttpMethod = "POST"
in the AjaxOptions.
Anyways hopefully this may help you or someone else, so I posted it here.
Could not figure this out. So in the end I just used jquery.ajax instead.
