Calling jQuery function from C#

Question

I have the function below which needs to be called from C#

$('.image-cropper').each(linkUp);

Can anyone explain how it could be done. I tried using the below code

    String csname1 = "PopupScript";
    Type cstype = this.GetType();
    ClientScriptManager cs = Page.ClientScript;
    StringBuilder cstext2 = new StringBuilder();
    cstext2.Append("<script type=\"text/javascript\"> $('.image-cropper').each(linkUp); </");
    cstext2.Append("script>");
    cs.RegisterClientScriptBlock(cstype, csname1, cstext2.ToString(), false);

but it did not work.

You probably need to wrap your JS in $(document).ready() so the DOM's loaded when you try to select elements — Clive

What browser are you using ? does it have a development console that can show you errors ? I ask, as it maybe that your emitted Javascript is executing before jQuery is added to the page. — Russ Clarke

Why is your question tagged with asp.net-mvc? I sincerely hope you are not using anything like this in an ASP.NET MVC application. — Darin Dimitrov

You should really be calling your code inside the jQuery ready function ie:

$(function() {
    $('.image-cropper').each(linkUp);
});

The likely reason your code wasn't working was that the image-cropper elements weren't in the DOM when your code was run.
