jQuery syntax error?

Question 1

Question by user1977591

user1977591

I found an example here on stackoverflow that I am trying to recreate and use a solution.
here is the link to the example: Refreshing Partial View in MVC 3

what is wrong with my syntax?

function RefreshPartial() {
        $('#invited-teams').load('/Challenge/GetInvitedTeams', {Model.ChallengeId});
    }

will this work? or does it need to have the curly brackets?

function RefreshPartial() {
        $('#invited-teams').load('/Challenge/GetInvitedTeams', "<%= Model.ChallengeId %>" );
    }

UPDATE:

 function RefreshPartial() {
        $('#invited-teams').load('/Challenge/GetInvitedTeams',
            {'paramname' : <%:Model.ChallengeId %> });
    }

my partial view:

            <div id="invited-teams">
                <% Html.RenderPartial("InvitedTeams", Model.InvitedTeams); %>
            </div>

So, this is what my refreshPartial method is looking like:

function RefreshPartial() {
        alert("in refresh partial");
        alert("<%:Model.ChallengeId %>");
        $('#invited-teams').load('/Challenge/GetInvitedTeams', { 
            'paramname': '<%:Model.ChallengeId %>'
        });


    }

it alerts both alerts correctly, with the 2nd one having the correct ChallengeID. The page is still going blank though. hmm..

Your function does not specify a parameter name.

function RefreshPartial() {
    $('#invited-teams').load('/Challenge/GetInvitedTeams', {
       'paramname' :'<%:Model.ChallengeId %>'//Or your ASP wrapper here
    });
}

Question 2

Question by Andrey Lima Ramos

Andrey Lima Ramos

I am using MVC3.
I have a table and an Html.ActionLink inside of it.
I have already set the text decoration for none, but the link is still blue. I change the table:hover background-color and the color(of the text), and when I put the mouse over the row, the text that are not a link gets white, but the link still blue. If I change the a:hover, the link gets white just when I put the mouse over it, and not just over the row.

Is there a way to do that with css?

Answer

Answer by Starx

Starx

Typically, to cover all the anchors when you are hovering over the row.

#tableid tr:hover a {
    /* Your Styles */
}

But this does not work on all IE browser so, use JS to catch the event and apply styles to anchors in it.

Question 3

This is My HTML Dom:

<input type="checkbox" class="chk-act" name="actionChk" value="17">
<input type="checkbox" class="chk-act" name="actionChk" value="18">
<input type="checkbox" class="chk-act" name="actionChk" value="19">
<input type="checkbox" class="chk-act" name="actionChk" value="20">
<input type="checkbox" class="chk-act" name="actionChk" value="21">

And I have a jQuery script that returned a JSon response by ajax:

["18","20","21"]

The list can be as long as up to 200 members. So I am interested to find out the fastest way to checked checkboxes, that have a value in above list, when the response is returned. What is your suggestion?

The fastest way would be to add an id identifier to your list of checkboxes. For example –

<input type="checkbox" class="chk-act" name="actionChk" value="17" id='chk-act-17' />
//incidentally, I hope the lack of a closing '/' was an oversight
//when you get your JSON response, in your ajax success or done methods
var resp = ["12", "232"],
    respLength = resp.length;
for(var i = 0; i < respLength; i += 1){
    $('#chk-act-' + resp[i]).prop('checked', true);
    //if your are using jquery 1.7+ that is, otherwise use, 
    $('#chk-act-' + resp[i]).attr('checked', 'checked');
}

JS Perf Tests

Comparing the two current answers, the OP’s requirement of “fastest” would be better served by going down the uglier ‘id‘ implementation.

    checkboxes = $('.chk');

checkboxes.each(function(i, item){
    $(this).prop('checked', false);
});

arr.forEach(function(item, i) {
    $('#chk_' + item).prop('checked', true);
});

Mixing jQuery on this

arr = ["18","20","21"];
$("input:checkbox").prop('checked', false); //If you need to uncheck other boxes too
$.each(arr, function(k,v) {       
   $("input[value=""+v+""]").prop('checked', true);
});

This javascript will find all my selects and validate them but I want to add that it doesnt validate my disabled selects. How can I code that in my javascript?

$("#next-step").click(function () {

                var $step = $(".wizard-step:visible"); // get current step

                var validator = $("form").validate(); // obtain validator
                var anyError = false;
                $step.find("select").each(function () {
                    if (!validator.element(this)) { // validate every input element inside this step
                        anyError = true;
                    }


                });

                if (anyError)
                    return false; // exit if any error found

Thanks in advance!

if (!this.disabled && !validator.element(this)) {
    anyError = true;
}

or (slower)

$step.find("select:enabled").each(function() {
    if (!validator.element(this)) {
        anyError = true;
    }
});

The easiest way, i know of is to give the select tags, a class like skipvalidation and then

$("form").validate(
   ignore: ".skipvalidation"
);

You can find all the disabled elements and add the class as

$("input:disabled").addClass("skipValidation");
$("form").validate(
   ignore: ".skipvalidation"
);
