Uncaught Error: no such method 'value' for selectmenu widget instance

问题

I've installed the 1.10 version of jQuery and I am getting this error when trying to set the value as the way I've always done so with the selectmenu widget.

Error: Uncaught Error: no such method 'value' for selectmenu widget instance

$('select.widthOpts').selectmenu('value', wDims.feet);

I also receive the same error when attempting to set the index of the selectmenu.

回答1:

Are you aware there are two versions?

https://github.com/fnagel/jquery-ui/ (old, fork of filament groups work) https://github.com/jquery/jquery-ui/tree/selectmenu (new, official)

The new one does not have value or index methods.

Since you are getting error, I reckon you are using new version.

So you should use $('select.widthOpts').selectedIndex=index; where index is a integer value that you already know the position of the required option in selectmenu

回答2:

the below code also works fine. I am using jQuery 1.10.2 and jquery-ui 1.11.1

$('select.widthOpts').val(wDims.feet).selectmenu('refresh')
