本文介绍了jQuery自动完成与类别选择的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在使用带有类别选项的jquery automplete,一切正常.现在我想使类别可以选择.我经历了很多事情,但是没有任何作用.有没有办法使类别可选择而不是标签. /p>
我的代码如下:
$.widget("custom.catcomplete", $.ui.autocomplete, {
_renderMenu: function (ul, items) {
var self = this;
var currentCategory = "";
$.each(items, function (index, item) {
if (item.category != currentCategory) {
ul.append("<li class='ui-autocomplete-category'>" + item.category + "</li>");
currentCategory = item.category;
}
self._renderItem(ul, item);
});
},
});
$('#city').catcomplete({
delay:0,
source : function(request, response) {
$.ajax({
url : '${createLink(controller:"city", action:"ajaxData")}',
data : {
term : request.term
},
dataType : "json",
success : function(data) {
if (data.length > 0) {
response( $.map( data, function( item ) {
return {
label: item.label,
value: item.category,
category: item.category,
}
}));
}
else{
response([{ category: 'No results found', val: "",label:""}]);
}
}
});
},
focus: function(event, ui) {
$("#city").val(ui.item.category);
return false;
} ,
select: function( event, ui ) {
window.location.href = ui.item.category;
},
});
解决方案
这将解决您的问题,但可能不是最佳解决方案.
我做了什么
- 为类别选项添加了一个单击事件侦听器,它将调用
selectHandler()
来处理从自动完成列表中选择的选项. - 通过将
ui-menu-item
类添加到<li>
标签来将类别选项构建为菜单项,这将赋予类别选项与列表中其他选项相同的视觉效果.
实时演示@ JSFiddle:

JS代码:
$(document).on('click', '.ui-autocomplete-category', function () {
$("#search").val($(this).html());
$("#search").catcomplete("close");
selectHandler($(this).html());
});
var selectHandler = function (data) {
//process selected data
console.log("selected value: " + data);
};
快乐编码:)
I am using jquery automplete with category option, everything is working fine.Now i want to make categories select-able.I have gone through many things but nothing is working.Is there any way to make category selectable not label.
My code is as below:
$.widget("custom.catcomplete", $.ui.autocomplete, {
_renderMenu: function (ul, items) {
var self = this;
var currentCategory = "";
$.each(items, function (index, item) {
if (item.category != currentCategory) {
ul.append("<li class='ui-autocomplete-category'>" + item.category + "</li>");
currentCategory = item.category;
}
self._renderItem(ul, item);
});
},
});
$('#city').catcomplete({
delay:0,
source : function(request, response) {
$.ajax({
url : '${createLink(controller:"city", action:"ajaxData")}',
data : {
term : request.term
},
dataType : "json",
success : function(data) {
if (data.length > 0) {
response( $.map( data, function( item ) {
return {
label: item.label,
value: item.category,
category: item.category,
}
}));
}
else{
response([{ category: 'No results found', val: "",label:""}]);
}
}
});
},
focus: function(event, ui) {
$("#city").val(ui.item.category);
return false;
} ,
select: function( event, ui ) {
window.location.href = ui.item.category;
},
});
解决方案
This will solve your problem , but may not be the best solution.
What I have done
- added a click event listener for the category option and it would call the
selectHandler()
to process the selection of the option from the autocomplete list. - building the category option as a menu item by adding
ui-menu-item
class to the<li>
tag, which will give the category option the same visual effects as that of other options in the list.
Live Demo @ JSFiddle:

JS Code :
$(document).on('click', '.ui-autocomplete-category', function () {
$("#search").val($(this).html());
$("#search").catcomplete("close");
selectHandler($(this).html());
});
var selectHandler = function (data) {
//process selected data
console.log("selected value: " + data);
};
Happy Coding :)
