Datepicker value resets when convertBack in use

[naxellar]

I am using datepicker control from Sample tag controls.

{^{datepicker date _dateFormat='dd/mm/y'
   convert='toDateString' convertBack='toWcfDate'}}
   <input type="text" value=""/>
{{/datepicker}}

toDateString converter returns date in datepicker format, toWcfDate converter gets datepicker format and returns ASP.NET format (e.g. /Date(1198908717056-0700)/).

When user interact with datepicker, model stores correct value but datepicker control is assigning ASP.NET format value that brings to resetting date to default.

See JSFiddle demo

I found that here datepicker is assigning raw model value and this method are calling after user chose date in picker.

// jsviews-jqueryui-widgets.js
...
setValue: function (value) {
  if (value !== undefined && value !== this.value) {
    this.value = value;
    this.linkedElem.datepicker("setDate", value);
  }
},
...

Did I do something wrong or it is a bug? Do you support Sample tag controls or not? Thank you.

Hi, Yes that is a bug. The fix is to change the following line

https://github.com/BorisMoore/jsviews.com/blob/gh-pages/download/sample-tag-controls/jsviews-jqueryui-widgets.js#L285

to

tag.setValue(tag.cvtArgs()[0]);

I'll include that in the next update.

Thanks for catching this!

It works. Thank you for you help.

In fact there is another small change. The onAfterLink function should be like this:

  onAfterLink: function(tagCtx) {
    var tag = this;
    tag.baseApply(arguments);
    tag.setValue(tag.cvtArgs()[0]);
    if (tag.linkedElem[0].tagName !== "INPUT") {
      // This datepicker is not using an input (e.g. using a div) - so set to inline-block
      tag.linkedElem.css("display", "inline-block");
    } else {
      tag.tagCtx.props.trigger = false;
    }
  }

I am thinking to add a sample showing use of converters with the {{datepicker}} tag control. Would you be OK if I use your code for the converters, using moment.js, within the sample?

[naxellar]

It is OK, welcome to use where you want.

[BorisMoore]

Good, thanks, I'll do that... :)
