JQuery的自动完成。如果无法找到项目，显示和QUOT; preSS Enter键插入自动完成＆QUOT;？ [英] JQuery Autocomplete. If item cannot be found, display "Press Enter to insert into autocomplete"?

问题描述

我做怎样的一个标签，自动完成组合的。

I am doing kind of a tag-autocomplete combo.

所以基本上，当用户进入一个没有自动完成选项的查询，即AAA，我想自动完成，以砸下来，并显示preSS'回车'创造'AAA'的标签。

So basically when user enters a query that has no autocomplete options, i.e "aaa", I want autocomplete to drop down and display "Press 'Enter' to create a tag for 'aaa'. "

我无法找到的文档（我想这需要我做一些黑客行为，但在这样做之前，我想看看是否有人做这个补丁。）

I can't find anything on the docs (I suppose this requires me to do some hacking, but before doing so, I wanna see if anyone has done a patch for this.)

编辑：

我已经开始在源$ C ​​$ C工作，这是我有：

I have began working on the source code and this is what I have:

 $.ui.autocomplete.prototype._response= function( content ) {
    /* BUG: when the user clicks "Press Enter to this tag", 
     *  the tag "Press enter to create this tag" 
     *  gets created
     */
    console.log(content);
    if (content.length == 0) { 
      content = [{ 'label': "Press Enter to create this tag.", "value": -1 }];
    }

    if ( !this.options.disabled && content && content.length ) {
      content = this._normalize( content );
      this._suggest( content );
      this._trigger( "open" );
    } else {
      this.close();
    }
    this.pending--;
    if ( !this.pending ) {
      this.element.removeClass( "ui-autocomplete-loading" );
    }
  };

这工作正常。然而，当，当用户点击preSS输入到这个标签，标签preSS输入来创建此标签被创建。如何解决这个原来的查询？

This works fine. However, when the when the user clicks "Press Enter to this tag", the tag "Press enter to create this tag" gets created. How do I fix this to the original query?

推荐答案

我不知道你如何让你自动完成的结果，但如果如你得到它的$ .getJSON（）调用，填充组合的项目根据其结果（不只是给调用的结果直到控制）可以检查是否result.length == 0，如果是的话，加入其他的东西（像元件说preSS输入创建）来组合。

I don't know how you get you're autocomplete results, but if for example you're getting it in a $.getJSON() call, and filling the combo's items based on the result (and not just giving the result of the call straight to the control) you could check whether the result.length == 0, and if so, add something else (like an element saying "Press Enter to create") to the combo.

请表现出一定的code，如果你想要更多的precise答案！
