I have a Jquery UI autocomplete code that grabs data from an ajax request, as i grab the data the results are already put in the input box where the autocomplete is attached. my problem is i have a other data along the data that will be posted with the result of the autocomplete.

I had tried to grab all the i need and put it in a single string with delimeters so i can split() it on the client-side. I want to save the other data in a hidden text field

here is my code

    <div id="01ac091c834d81b41f0ef4b6eb09cde90bb9aa1a" style="display:none" title="Add Member">
        Type the name of the member
        <br>
        <br>
        <div style="text-align:center">
            <input type="text" id="txtUserFind" size="35">
        </div>
        <input type="hidden" id="hidtxtUserFind-nickname">
        <input type="hidden" id="hidtxtUserFind-userhash">
        <input type="hidden" id="hidtxtUserFind-picture">
        <input type="hidden" id="hidtxtUserFind-sex">
    </div>
    <script type="text/javascript">
    head(function() {


        $(":button:contains('Select User')").attr("disabled","disabled").addClass("ui-state-disabled");

        $("#txtUserFind").keydown(function(){
            $(":button:contains('Select User')").attr("disabled","disabled").addClass("ui-state-disabled");
        });


        $("#txtUserFind").change(function(){

        var userdetails = $("#txtUserFind").val().split(";");
        alert($("#txtUserFind").val());

        /*
        0  profiles.nickname,
        1  profiles.firstname,
        2  profiles.surname,
        3  users.user_hash,
        4  profiles.sex,
        5  profiles.picture
        */

        $("input#hidtxtUserFind-nickname").val(userdetails[0]);
        $("input#txtUserFind").val(userdetails[1] + " " + userdetails[2]);
        $("input#hidtxtUserFind-userhash").val(userdetails[3].replace("u-",""));
        $("input#hidtxtUserFind-sex").val(userdetails[4]);
        if(userdetails.length > 5){
            $("input#hidtxtUserFind-picture").val(userdetails[5]);
        }   

        });

        $("<?php echo $tagmemberbtn; ?>").click(function(){
            $("#01ac091c834d81b41f0ef4b6eb09cde90bb9aa1a").dialog({

你的想法是对的，你必须使用回调作为source参数。我在这里整理了一个例子：

jsFiddle 上的演示

如果您仔细阅读文档，它会说：

第三种变体，回调，提供了最大的灵活性，可用于将任何数据源连接到自动完成。回调有两个参数：

一个请求对象，具有一个名为“term”的属性，它指的是文本输入中当前的值。例如，当用户在城市字段中输入“new yo”时，自动完成项将等于“new yo”。

响应回调，它期望单个参数包含要向用户建议的数据。此数据应根据提供的术语进行过滤，并且可以采用上述简单本地数据的任何格式（字符串数组或具有标签/值/两个属性的对象数组）。在请求期间提供自定义源回调以处理错误时，这一点很重要。即使遇到错误，您也必须始终调用响应回调。这确保了小部件始终具有正确的状态。

所以这是我在演示中使用的示例实现：

$("#autocomplete").autocomplete({
    source: function(request, response) {
        $.ajax({
            url: "/echo/html/", // path to your script
            type: "POST",       // change if your script looks at query string
            data: {             // change variables that your script expects
                q: request.term
            },
            success: function(data) {
                                // this is where the "data" is processed
                                // for simplicity lets assume that data is a
                                // comma separated string where first value is
                                // the other value, rest is autocomplete data
                                // the data could also be JSON, XML, etc
                var values = data.split(",");
                $("<div/>").text("Other value: " + values.shift()).appendTo("body");
                response(values);
            },
            error: function() {
                response([]);   // remember to call response() even if ajax failed
            }
        });
    }
});

您可以在选择时包含一个功能。在该函数中，您可以根据需要访问所选项目和进程的值和标签：

$('#input_id').autocomplete({
    source:"www.example.com/somesuch",
    select: function(event, ui){
        var value = ui.item.value;
        valueArray = value.split('whatever delimiter here');
        //do what you will with the values
        ui.item.value = ui.item.label; //This ensures only the label is displayed after processing.
    }
});
