jquerymobile conflict with autocomplete : $this.attr("href") is undefined

开发者 https://www.devze.com 2023-01-30 05:56 出处：网络

When I use jquery ui autocomplete version 1.8.5 with jquery mobile alpha 2. I get an error when I click an item from the autocomplete list:

$this.attr("href") is undefined.

Does anyone know any fix for it?

Modified jquery.mobile-1.0a2.js: Added a check to see if href is undefined inside the code

  $( "a" ).live( "click", function(event) { 
           //( START: My added code) 
            if($(this).attr( "href" )==undefined){
                //for links created for interaction - ignore
                return false;
            }
           //( END: My added code) 
   //Remaining code follows

This fixed the issue.

Hey sweets, thanks for pointing me in the right direction.

I find it's better to override the jquery ui code rather than modify the jquery mobile source code directly (for the sake of maintainability). The following overrides the jquery-ui method that renders each item in the autocomplete list; it adds an href attribute with value of '#' to the anchor element being created. This should prevent the undefined href error:

$('#to').data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
    .data( "item.autocomplete", item )
    .append( $( "<a></a>" ).attr({href: '#'}).html( item.label ) )
    .appendTo( ul );

}

$(this) not $this.
