在stackoverflow上发布我的第一个问题。我从来没有发生过stackoverflow无法为我提供已经发布的答案但是第一次的所有内容。这是我一直在努力解决的问题：
我使用HTML表单将数据（特定值）从一个页面传输到另一个页面（不了解PHP）。在专用网站上，我有一个列表组合，可以通过更改输入和选择（下拉列表）进行过滤。过滤系统的JQuery完美运行。但是，我编写了一些JS，它们将这些选择的值更改为延迟后从上一个站点传输的值，但此更改不会触发＆＃34;选择更改＆＃34;过滤系统的事件。下面是在网站上运行的JS。同样，当我手动更改select时，过滤器系统会工作，但是当我的JS代码在底部更改select时，它不会执行。
欢迎任何建议。
谢谢！
jQuery(window).load( function(){
var filters = {};
var $container = $('.grid-container');
$container.isotope();
$('.combination-filter').on( 'change', 'select', function() {
var $this = $(this);
// get group key
var $buttonGroup = $this.closest('.btn-groupn');
var filterGroup = $buttonGroup.attr('data-filter-group');
// set filter for group
filters[ filterGroup ] = $this.find('option:selected').attr('data-filter');
// combine filters
var filterValue = concatValues( filters );
$container.isotope({ filter: filterValue });
return false;
});
// flatten object by concatting values
function concatValues( obj ) {
var value = '';
for ( var prop in obj ) {
value += obj[ prop ];
}
return value;
}
$(window).resize(function() {
$container.isotope('layout');
});
function initselect() {
var parameters = location.search.substring(1).split("&");
var temploca = parameters[0].split("=");
loca = unescape(temploca[1]);
$("input[name=locations]").val(loca);
var tempsqua = parameters[1].split("=");
squa = unescape(tempsqua[1]);
$("select[name=squarems]").val(squa);
var temppric = parameters[2].split("=");
pric = unescape(temppric[1]);
$("select[name=pricings]").val(pric);
};
setTimeout(initselect, 1000)
});

******* ******** EDIT
你好！
我已将以下代码添加到initselect函数，现在它确实执行了过滤器。但是，不知怎的，它现在没有填写最后一个选择（价格）。它留空，因此也不包括在过滤器中。过滤器现在可以自动更改第一个选择。这是在js：
更改选择后在initselect函数中执行的代码$(".combination-filter select").each(function() {
var $this = $(this);
// get group key
var $buttonGroup = $this.closest('.btn-groupn');
var filterGroup = $buttonGroup.attr('data-filter-group');
// set filter for group
filters[ filterGroup ] = $this.find('option:selected').attr('data-filter');
// combine filters
var filterValue = concatValues( filters );
$container.isotope({ filter: filterValue });
return false;
});
答案 0 :(得分：2)
您需要从代码中调用post事件=＆gt; .change()。
如果以编程方式更改值，则更改事件不会“由浏览器调用”。
答案 1 :(得分：0)
此问题的解决方案如下。而不是
$("select[name=squarems]").val(squa);
我必须添加.change（）;对于initselect（）函数中每个val更改的结尾。这看起来像这样（每个）：
$("select[name=squarems]").val(squa).change();
不知何故，这使得它注册为一个更改，并在JS中触发了过滤器事件。
感谢大家的投入！
干杯
