jQuery自动完成功能开始按字符"@" [英] jquery autocomplete to start on pressing character '@'

问题描述

我有一个文本区域，可以在其中编写消息.我想为某些条件激活jquery自动完成功能 -当用户按"@"时，他们应该开始看到建议，直到不按空格为止.

I have a textarea in which I write messages. I want to activate jquery autocomplete for certain condition like - when user presses '@', they should start seeing the suggestion till they dont press space.

这类似于Facebook风格的@friends预测.

It is something similar to facebook style @friends prediction.

jquery本质上支持此吗? 有什么想法吗?

Does jquery inherently support this? Any ideas?

推荐答案

我认为最简单的方法是向源代码提供功能.像这样:

I think the easiest way to do this is to provide a function to source. Something like this:

textbox.autocomplete({
    source: function (request, response) {
        var lastWord = request.term.split(/,\s*/).pop();
        if (lastWord.indexOf('@') == -1) {
            return [];
        }
        $.getJSON('YourUrl' + lastWord, {}, function (data) {
            response(values);
        });
    }
});

这仅在最后一部分是自动完成的情况下有效.

This will only work if the last part is the one being autocompleted though.
