I'm really new to jQuery and Charts. This is my script, it works fine. It gives me the id of the checkboxes selected by the user. I have a Chart action in my controller which also works fine, but it creates a chart using all my values. I want it to create a chart based on the selected values that are in my script. I don't know how to pass the selected values to my controller.
var checkboxes = $("input[type='checkbox']");
$(function ()
{
function getValueUsingClass() {
/* declare an checkbox array */
var chkArray = [];
/* look for all checkboes that have a class 'chk' attached to it and check if it was checked */
$(".chk:checked").each(function () {
chkArray.push($(this).val());
});
/* we join the array separated by the comma */
var selected = chkArray.join(",") + ",";
/* check if there is selected checkboxes, by default the length is 1 as it contains one single comma */
if (selected.length > 1)
{
alert("You have selected " + selected);
}
else
{
alert("Please check at least one of the checkbox");
}
}
$("#Charter").click(function () {
getValueUsingClass();
});
});
Return the data you want in your js function after populating the variable using return selected;
then send it back by posting a form or using ajax.
Bind your data to an element on your View page, for example:
<input name="foo" id="yourId" value="bar" />
then modify it's value:
$('#foo').val(getValueUsingClass());
and pass the model back by posting your form to your controller.
If you wish to send data to your controller async then you can look into Ajax .
You can use ajax to call your controller method within getValueUsingClass()
.
It would probably look something like this:
$.ajax({
url: "/YourControllerName/Chart",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: { arr: chkArray },
success: function () {
// do things upon success
},
error: function () {
alert("Error!");
}
});
That is, providing your Controller action has a parameter named arr
, because json maps chkArray
to it once it is passed to the Controller.
