我有以下自动填充代码,效果很好。
我只想在AJAX调用期间添加一个显示加载图像的类,并在AJAX调用完成后删除加载图像。
我知道我可以使用addClass和removeClass的jQuery来做。问题是我无法理解我应该在哪一行添加addClass以及我应该添加removeClass的哪一行。
你能帮忙吗? (function( $ ) {
$(function() {
// Custom autocomplete instance.
$.widget( "app.autocomplete", $.ui.autocomplete, {
// Which class get's applied to matched text in the menu items.
options: {
highlightClass: "ui-state-highlight"
},
_renderItem: function( ul, item ) {
// Replace the matched text with a custom span. This
// span uses the class found in the "highlightClass" option.
var re = new RegExp( "(" + this.term + ")", "gi" ),
cls = this.options.highlightClass,
template = "<span class='" + cls + "'>$1</span>",
label = item.label.replace( re, template ),
$li = $( "<li/>" ).appendTo( ul );
// Create and return the custom menu item content.
$( "<a/>" ).attr( "href", "#" )
.html( label )
.appendTo( $li );
return $li;
}
});
var autocompleteTextbox = '<div class="autocomplete-search autocomplete-search-open">'
+'<a href="#" class="st-btn01 autocomplete-search-icon"><i class="search-icon" aria-hidden="true"></i></a>'
+'<div class="autocomplete-search-sub1">'
+'<form role="search" method="get" action="<?php echo esc_url( home_url( '+"/"+' ) ); ?>">'
+'<input type="text" name="s" class="form01 autocomplete-search-input" id="autocomplete-search-input" placeholder="Type something" autocomplete="off">'
+'<a href="#" class="st-btn02 autocomplete-search-icon"><i class="searchx-icon" aria-hidden="true"></i></a>'
+'</form>'
+'</div>'
+'</div>';
var appendElement = function(){
$('.st-navbar-collapse').append(autocompleteTextbox);
$(this).unbind('click');
$(".st-search .st-btn01 .search-icon").addClass('text-visibility');
};
$(".two-brokers").parent('a').on('click',appendElement);
var removeElement = function(){
$(this).parents('.autocomplete-search').remove();
$(".two-brokers").parent('a').bind('click',appendElement);
$(".st-search .st-btn01 .search-icon").removeClass('text-visibility');
};
$("body").on("click",".st-btn02.autocomplete-search-icon",removeElement);
var searchRequest,timeoutRequest;
$("body").on("keyup",".autocomplete-search-input",function(){
clearTimeout(timeoutRequest);
var _this = $(this);
timeoutRequest = setTimeout(function(){
// create an jq-ui autocomplete on your selected element
_this.autocomplete({
minChars: 2,
highlightClass: "bold-text",
// use a function for its source, which will return ajax response
source: function(request, response){
try { searchRequest.abort(); } catch(e){}
// well use postautocomplete_search.ajax_url which we enqueued with WP
$.post(postautocomplete_search, {
action: 'get_test_pages', // our action is called search
term: request.term // and we get the term form jq-ui
}, function(data) {
if(!data.length){
var result = [{
label: 'No matches found',
value: response.term
}];
response(result);
}else{
response(data);
}
}, 'json');
},
select: function( evt, ui ) {
evt.preventDefault();
window.location = ui.item.link;
}
});
},100);
});
});
})( jQuery );

您只需要添加一个类**name1, name2**
**DATE** **P1, P2; P1; P2**
date1, 2.0, 3.0; 3.4, 2.4
date2, 3.1, 2.3; 2.0, 3.0
,其背景图片符合指定here。
它会自动检测类,并在请求完成时添加和删除加载图像。
.ui-autocomplete-loading

您可以将div设置为隐藏在模板上,然后在需要时隐藏并显示
<div class="loader"></div>
和那个
的css.loader {
border: 16px solid #f3f3f3; /* Light grey */
border-top: 16px solid #3498db; /* Blue */
border-radius: 50%;
width: 120px;
height: 120px;
animation: spin 2s linear infinite;
}
@keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
当你试图做ajax时,应该显示它,当你返回resule时隐藏它。

我只复制了代码的相关部分并添加了我将放置addClass()/ removeClass()。
这是输入密钥的ADD ...以及.post()
回调的删除。
$("body").on("keyup",".autocomplete-search-input",function(){
// ADD on keyup
$("#loaderImgId").addClass("spin");
clearTimeout(timeoutRequest);
var _this = $(this);
timeoutRequest = setTimeout(function(){
// create an jq-ui autocomplete on your selected element
_this.autocomplete({
minChars: 2,
highlightClass: "bold-text",
// use a function for its source, which will return ajax response
source: function(request, response){
try { searchRequest.abort(); } catch(e){}
// well use postautocomplete_search.ajax_url which we enqueued with WP
$.post(postautocomplete_search, {
action: 'get_test_pages', // our action is called search
term: request.term // and we get the term form jq-ui
}, function(data) {
// REMOVE when Ajax result is in!
$("#loaderImgId").removeClass("spin");
if(!data.length){
var result = [{
label: 'No matches found',
value: response.term
}];
response(result);
}else{
response(data);
}
}, 'json');
},
select: function( evt, ui ) {
evt.preventDefault();
window.location = ui.item.link;
}
});
},100);
});
