如何在SlickGrid单元格编辑器中实现jQuery自动完成

Question

我正在设置SlickGrid,需要有一个带有autoComplete编辑器的列.我尝试了修改TextEditor或DateEditor.什么都行不通.

任何人都可以使用TextEditor作为基础给我一个粗略的草图吗？

非常感谢.

我在slick.editors.js中做了这个 - 可能有一些bug,但应该可以帮助你开始:

$.extend(true, window, {
    "Slick": {
      "Editors": {
        "Auto": AutoCompleteEditor,
        "Text": TextEditor,
        "Integer": IntegerEditor,
        "Date": DateEditor,
        "YesNoSelect": YesNoSelectEditor,
        "Checkbox": CheckboxEditor,
        "PercentComplete": PercentCompleteEditor,
        "LongText": LongTextEditor
      }
    }
  });

  var availableTags = [
                        "ActionScript",
                        "AppleScript",
                        "Asp",
                        "BASIC",
                        "C",
                        "C++",
                        "Clojure",
                        "COBOL",
                        "ColdFusion",
                        "Erlang",
                        "Fortran",
                        "Groovy",
                        "Haskell",
                        "Java",
                        "JavaScript",
                        "Lisp",
                        "Perl",
                        "PHP",
                        "Python",
                        "Ruby",
                        "Scala",
                        "Scheme"
                      ];

   function AutoCompleteEditor(args) {
     var $input;
     var defaultValue;
     var scope = this;
     var calendarOpen = false;

     this.init = function () {
       $input = $("<INPUT id='tags' class='editor-text' />");
       $input.appendTo(args.container);
       $input.focus().select();
       $input.autocomplete({
            source: availableTags
        });
     };

     this.destroy = function () {
       $input.autocomplete("destroy");
     };

     this.focus = function () {
       $input.focus();
     };

     this.loadValue = function (item) {
       defaultValue = item[args.column.field];
       $input.val(defaultValue);
       $input[0].defaultValue = defaultValue;
       $input.select();
     };

     this.serializeValue = function () {
       return $input.val();
     };

     this.applyValue = function (item, state) {
       item[args.column.field] = state;
     };

     this.isValueChanged = function () {
       return (!($input.val() == "" && defaultValue == null)) && ($input.val() != defaultValue);
     };

     this.validate = function () {
       return {
         valid: true,
         msg: null
       };
     };

     this.init();
   }

如果这有帮助,请告诉我.

只是前一个答案的一点点补充.要使箭头键工作,您可能想要这样做stopPropagation.这是编辑器init方法的片段.这是在CoffeeScript中你会得到这个想法:

$input.bind "keydown.nav", (e) ->
    e.stopPropagation() if (e.keyCode == $.ui.keyCode.DOWN || e.keyCode == $.ui.keyCode.UP || e.keyCode == $.ui.keyCode.ENTER) && $('ul.ui-autocomplete').is(':visible')
    e.stopImmediatePropagation() if e.keyCode == $.ui.keyCode.LEFT || e.keyCode == $.ui.keyCode.RIGHT

上面代码片段的常规JQuery翻译:

$input.bind("keydown.nav", function(e) {
    if ((e.keyCode == $.ui.keyCode.DOWN || e.keyCode == $.ui.keyCode.UP ||
         e.keyCode == $.ui.keyCode.ENTER)
      && $('ul.ui-autocomplete').is(':visible')) e.stopPropagation();

    if (e.keyCode == $.ui.keyCode.LEFT || e.keyCode == $.ui.keyCode.RIGHT)
        e.stopImmediatePropagation();
});
