在动态生成的输入上委托预先输入 [英] To delegate typeahead on dynamically generated input
问题描述
我有一个html表格,我正在使用它来输入库存详细信息。在这个表格中,我有一个输入框用于产品名称,我在其上绑定typeahead事件的bootstrap.But问题是,对于第一行输入框当它被呈现时它已经出现在页面上,typeahead工作正常。但是当我为更多条目添加新行时,typeahead不会与它们一起工作。我知道事件委托的概念,但问题是我没有知道如何在这种情况下实施它。诚挚地指导我通过这个。
提前致谢。
这是我的html表格 -
I have a html table which i am using to enter the inventory details .In this table I have a input box for product name on which I am binding typeahead event of bootstrap.But the problem is that for the first row input box which is already present on the page when it is rendered, typeahead works fine.But when i add new rows for more entries, typeahead does not works with them.I know about the concept of event delegation but the problem is that I don't know how do i implement it in this case.Kindly guide me through this. Thanks in advance. Here is my html table-
<table>
<thead>
<tr>
<td>Product name</td>
<td>Amount</td>
</tr>
</thead>
<tbody class="details">
<tr>
<td><input type="text class="items" name="items" id="items" data-provide="typeahead" /> </td>
<td><input type="text" name="amt" id="amt" class="amt" /></td>
</tr>
</tbody>
</table>
这里是用于添加新行的javascript -
here is the javascript used to add new rows-
$(function(){
$('#add').click(function(){
addnewrow();
});
});
function addnewrow(){
var tr = '<tr>'+
'<td><input type="text" name="items" id="items" class="items" data-provide="typeahead" autocomplete="off" /></td>'+
'<td><input type="text" name="amt" id="amt" class="amt" autocomplete="off" /></td>'+
'</tr>';
$('.details').append(tr);
}
这是我如何使用typeahead -
Here is the how i have used typeahead-
$(function(){
$('#items').typeahead({
source: function(query,process){
$.ajax({
url: 'itemexist.php',
type: 'POST',
data: 'query=' +query,
dataType: 'JSON',
async: true,
success: function(data){
process(data);
}
});
}
});
});
我知道这个问题以前已经问过,但没有可接受的解决方案,我尝试了这些解决方案,但它不工作。
这是我试过的,但它似乎并不奏效 -
I know this question has been asked before but there is no accepted solution and I have tried those solutions but it is not working. Here is what I have tried,but still it doesn't seems to work-
$(document).on("keypress",".items",function(){
$('.items').typeahead({
source: function(query,process){
$.ajax({
url: 'itemexist.php',
type: 'POST',
data: 'query=' +query,
dataType: 'JSON',
async: true,
success: function(data){
process(data);
}
});
}
});
});
