动态添加行上的jQuery自动完成 [英] jquery Autocomplete on dynamically added rows

问题描述

我正在为我的Web应用程序使用jQuery UI自动完成插件.
对于我现有的行，它工作得很好，但是对于动态添加的行，它却不能正常工作.

I'm working with jQuery UI autocomplete plug-in for my web application.
It works perfectly fine for my existing rows, but doesn't quite work for my dynamically added rows.

这是我的jquery代码.

Here's my jquery code.

$(function ()
{
    var tab = $("#tabs-6");
tab.find("input[name='newContactName']").autocomplete(
{
        source: function(request, response) {
            var cachedRequest = $(this).data("cachedRequest");
            // Previous data is cached, so new data is a subset of this
            if (cachedRequest != null && 
                    cachedRequest.length > 0 && 
                    request.term.indexOf(cachedRequest) >= 0)
            {
                ..some code..
            }
            else
            {
                var input = $(this);
                $.ajax({
                    ..some code..
                    success: function(data) 
                    {..some code..
                    }

                }); 

            }
        },
        minLength: 3,
        delay: 500
    }
);

tab.find("input[name='newContactName']").bind('autocompleteselect', function(event, ui) {
    $(this).prev("input[name='newContactId']").val(ui.item.person_id);
    }); 

/* Customizing the autocomplete suggestions box that pops up.
*/
var input1=$("input[name='newContactName']"); 
input1.each(function (){
$(this).autocomplete("widget").css("height", "10em");
$(this).autocomplete("widget").css("overflow", "auto"); 
$(this).autocomplete("widget").css("width", "210px");
});

});

这是现有行的自动完成插件的jQuery代码，对于新添加的行，这是我要插入的html

This is the jQuery code for the autocomplete plugin for the existing rows, and for the newly added rows, this is the html I'm trying to insert

var html = '<tr>..first 8 td elements.. <td><input type="text" name="newContactName"> </td>'+
        ..some more td elements</tr>';

var newRow = $(html).insertAfter(row); // insert content,where row is my current row
newRow.find("td:nth-child(9) input[name='newContact']").autocomplete();

我如何确保自动完成功能也适用于我新添加的行?

How would I make sure that the autocomplete feature works for my newly added rows as well?

推荐答案

我看到了一些可能不对的地方.

I see a couple of things that might be wrong.

首先，当您添加新行时，将输入的名称设置为"newContactName"，但是当您找到find()时，将查找"name ='newContact'".

First, when you add a new row, you set the input's name to "newContactName", yet when you find() you look for "name='newContact'".

此外，在对find()的结果调用autocomplete()时，您需要指定source选项.由于您已在非动态行中将源设置为一个函数，因此您可能希望将其分解为一个命名函数，并在两个autocomplete()调用中都使用该命名函数作为源.

Also, when calling the autocomplete() on the results of find(), you'll need to specify the source option. Since you had source set to a function in your non-dynamic rows, you'll probably want to break that out to a named function and use the named function as the source in both autocomplete() calls.

希望这对您有帮助...
