Question

让我们考虑textbox中的值，所以现在如果我们自动输入它必须用逗号显示多值的单词。我试过但没有结果。

任何身体都可以解决这个问题。

  $(function()
            {
               var val = document.getElementById('tags').value;
               var availableTags = val == '' : [] ? val.split(',');

    function split( val ) {
      return val.split( /,\s*/ );
    }
    function extractLast( term ) {
      return split( term ).pop();
    }

    $( "#tags" )
      // don't navigate away from the field on tab when selecting an item
      .bind( "keydown", function( event ) {
        if ( event.keyCode === $.ui.keyCode.TAB &&
            $( this ).data( "ui-autocomplete" ).menu.active ) {
          event.preventDefault();
        }
      })
      .autocomplete({
        minLength: 0,
        source: function( request, response ) {
          // delegate back to autocomplete, but extract the last term
          response( $.ui.autocomplete.filter(
            availableTags, extractLast( request.term ) ) );
        },
        focus: function() {
          // prevent value inserted on focus
          return false;
        },
        select: function( event, ui ) {
          var terms = split( this.value );
          // remove the current input
          terms.pop();
          // add the selected item
          terms.push( ui.item.value );
          // add placeholder to get the comma-and-space at the end
          terms.push( "" );

根据我的理解，您的 autocomplete （我已在fiddle中测试过）并未填充。原因是 ternary operator语法错误。

 var availableTags = val == '' : [] ? val.split(',');  //WRONG

将此更改为

 var availableTags = val == '' ? [] : val.split(',');  //CORRECT

看到它在JSFiddle
