Question

我有一个HTML下拉列表，其中包含不同的值，如

STONY BROOK,11790
NY,100010
Tampa,77800

我使用下面的javascript

使用jquery自动完成组合框

我想要完成的是当用户点击组合框中的条目时，第一部分即STONY BROOK应保留在组合框中，下一部分(11790)应填入网页中的另一个文本字段。

知道如何做到这一点？

我做了类似

的事情

var array = city.split(',');

然后尝试做

ui.item.option.value(array[0]);

但是这给了我错误的说法

Uncaught TypeError: string is not a function

有什么想法吗？

找到实际问题很奇怪，但我找到了解决办法。

我修改了jquery-ui-1.10.3.js中的__response: function (content)。它没有尝试阻止，我添加了try catch，它解决了我的问题。如果有人为此问题找到了正确的解决方案，请在此处更新。

_response: function (content) {

        try{
            var message;
            this._superApply( arguments );
            if ( this.options.disabled || this.cancelSearch ) {
                return;
            }
            if ( content && content.length ) {
                message = this.options.messages.results( content.length );
            } else {
                message = this.options.messages.noResults;
            }
            this.liveRegion.text(message);
        }
        catch (e)
        {
            if (e != "TypeError: string is not a function")
            { alert("Error Occured in jquery-ui-1.10.3.js file at __response function ,error is " + e); }
        }
    }
