我有一个很好的工作jquery多列自动完成。现在我必须添加一个应该隐藏的列。基本上它是值的ID。因此,当用户选择值时,我可以获得所选行的ID。
//代码:
<script type="text/javascript">
var autocompleteSource;
var colValues = [];
var columns = [{ name: 'Workflow Name', width: '200px' }, { name: 'Workflow Category', width: '150px' }, { name: 'Status', width: '100px' }, { name: 'Workflow Owner', width: '150px' }];
$.ajax({
url: "/Home/LoadWorkflowDropdown",
datatype: 'json',
mtype: 'GET',
success: OnComplete,
error: OnFail
});
function OnComplete(result) {
autocompleteSource = $.parseJSON(result)
$.each(autocompleteSource, function () {
colValues.push([this.WorkflowName, this.WorkflowCategory, this.StatusName, this.UserName]);
});
$.widget('custom.mcautocomplete', $.ui.autocomplete, {
_renderMenu: function (ul, items) {
var self = this,
thead;
if (this.options.showHeader) {
table = $('<div class="ui-widget-header" style="width:100%"></div>');
$.each(this.options.columns, function (index, item) {
table.append('<span style="padding:0 4px;float:left;width:' + item.width + ';">' + item.name + '</span>');
});
table.append('<div style="clear: both;"></div>');
ul.append(table);
}
$.each(items, function (index, item) {
self._renderItem(ul, item);
});
},
_renderItem: function (ul, item) {
var t = '',
result = '';
$.each(this.options.columns, function (index, column) {
t += '<span style="padding:0 4px;float:left;width:' + column.width + ';">' + item[column.valueField ? column.valueField : index] + '</span>'
});
result = $('<li></li>').data('item.autocomplete', item).append('<a class="mcacAnchor">' + t + '<div style="clear: both;"></div></a>').appendTo(ul);
return result;
}
});
$("#search").mcautocomplete({
showHeader: true,
columns: columns,
source: colValues,
select: function (event, ui) {
this.value = (ui.item ? ui.item[0] : '');
return false;
}
});
}
</script>
在这里工作Fiddle

这里我修改了js代码,为每条记录添加唯一ID,并在用户从自动建议列表中选择特定选项时获取该值。 Fiddle
HTML:创建一个隐藏字段来存储所选选项的ID
<input type="hidden" name="selectedId" id="selectedId" />
JS:在数组中添加了id,并通过select
值在index
函数中检索了这些ID。
var columns = [{
name: 'Color',
width: '100px'},
{
name: 'Hex',
width: '70px'}],
colors = [['Red', '#f00', '1'], ['Green', '#0f0', '2'], ['Blue', '#00f', '3']];
$("#search").mcautocomplete({
showHeader: true,
columns: columns,
source: colors,
select: function(event, ui) {
$('#selectedId').val(ui.item[2]);
this.value = (ui.item ? ui.item[0] : '');
return false;
}
});
