使用 jqueryui 自动完成时的附加参数

发布于 2024-10-17 04:25:12 字数 572 浏览 8 评论 0原文

我希望向 jquery UI 自动完成请求添加一个附加参数，而不必将 json 返回嵌套在 ajax 调用中。我设想像下面这样工作，但是 data: 选项不会像普通的 jquery ajax 请求一样传递给 ajax 请求。

 $("#div").autocomplete({
        source: 'ajax.php',
        minLength: 2,
        data: '&action=getUserName',
        select: function( event, ui ) {
            log( ui.item ?
                "Selected: " + ui.item.value + " aka " + ui.item.id :
                "Nothing selected, input was " + this.value );
        }
});

tl;dr 我需要帮助将 &action=getUserName 传递给 ajax 以进行自动完成，最好不要将其嵌套在 ajax 回调中。

I'm looking to add an additional parameter to a jquery UI auto complete request without having to nest the json return in an ajax call. I would envision something like the following working, however the data: option is not passed over to the ajax request like it is on a normal jquery ajax request.

 $("#div").autocomplete({
        source: 'ajax.php',
        minLength: 2,
        data: '&action=getUserName',
        select: function( event, ui ) {
            log( ui.item ?
                "Selected: " + ui.item.value + " aka " + ui.item.id :
                "Nothing selected, input was " + this.value );
        }
});

tl;dr I need help passing &action=getUserName over to the ajax for my autocomplete, preferably without nesting it in an ajax callback.

试试这个：

$("#div").autocomplete({
        source: 'ajax.php',

        extraParams: {
            action: function() {
                  return "getUserName";
            }
        },
        minLength: 2,
        select: function( event, ui ) {
            log( ui.item ?
                "Selected: " + ui.item.value + " aka " + ui.item.id :
                "Nothing selected, input was " + this.value );
        }
});

根据文档： http://docs.jquery.com/Plugins/Autocomplete /autocomplete#url_or_dataoptions

编辑：添加了基于 jquery autocomplete extraParams 的更正

Try this instead:

$("#div").autocomplete({
        source: 'ajax.php',

        extraParams: {
            action: function() {
                  return "getUserName";
            }
        },
        minLength: 2,
        select: function( event, ui ) {
            log( ui.item ?
                "Selected: " + ui.item.value + " aka " + ui.item.id :
                "Nothing selected, input was " + this.value );
        }
});

per docs: http://docs.jquery.com/Plugins/Autocomplete/autocomplete#url_or_dataoptions

edit: added correction based on jquery autocomplete extraParams
