Question

I have a method that creates a form in my controller:

...
sbReturn.Append(String.Format("<p id='planSetupAddNewEffectiveDate'>"));
sbReturn.Append(String.Format("<label for='txtPlanSetupAddNewEffectiveDate'>Effective Date </label>"));
sbReturn.Append(String.Format("<input type='text' id='txtPlanSetupAddNewEffectiveDate' class='plansetupdate' />"));
sbReturn.Append(String.Format("</p>"));
...

Is there a way to attach a datepicker to that text field?

I’ve tried the standard

$(".plansetupdate").datepicker();

and

$("#txtPlanSetupAddNewEffectiveDate").datepicker();

but neither actually generates the datepicker. I know when trapping events from dymically added controls (ie. buttons) .live is used (ie. xxx.live(‘click’, function()…), is there something similar for this case?

Answer 1

You can use the .liveQuery() plugin for this, .live() didn’t fully replace it, your case is a prime example, you’d do this to get the result you’re after:

$(".plansetupdate").liveQuery(function() {
  $(this).datepicker();
});

For the why: The reason it isn’t working currently, is because when you execute $(".plansetupdate").datepicker(); what it’s doing is this:

• Find all elements with class planetsupdate
• Make datepickers on them

But…your element wasn’t there to find when it ran, it was added later. .liveQuery() continues to look. Altneratively, if you are loading this content via $.ajax() you could rig them up in your success or complete handler, like this:

$.ajax({
  //Stuff
  success: function(data) {
     $(".plansetupdate", data).datepicker();
  }
});

This would look inside your returned data for .planetsupdate elements to add new datepickers on.
