问题描述
< span id =builder-make-selectionclass =pick>
< span class =label>制作:< / span>
< div class =custom-dd-wrapper builder-makestabIndex =1>
< div class =custom_dd_select>
< span>
< a>讴歌< / a>< / span>
< / div>
< div class =custom_dd_options>
< ul class =custom_dropdown>
< li data-make =Acura> Acura< / li>
< li data-make =阿尔法罗密欧>阿尔法罗密欧< / li>
< li data-make =Audi>奥迪< / li>
< li data-make =宝马>宝马< / li>
< / ul>
< / div>
这里是创建下拉列表的javascript:
(function(h,a){
function k(){
var b = a(this).parents(div.custom_dd_wrapper),
f = b.attr(id),
e = a(b).find(。custom_dd_select a) ,
l = a(this).data(),
d = e.text()。trim(),$ b $ = a(this).text()。trim();
makes-options== f&&(a(b).addClass(active),e.parent(span)。attr(style,a(this).attr(风格)));
e.text(g);
for(var m in l){
if(m =='make'){
e.parent (span)。data(m,l [m]);
}
}
d!= g&& a(this).closest(。custom_dd_wrapper)。 trigger(change)
}
函数g(){
var b = a(this).closest(。custom_dd_wrapper);
a(b ).find( UL)。隐藏();
a(b).find(。custom_dd_select)。removeClass(click);
a(b).find(。custom_dd_options)。removeClass(show)
}
h.CustomDropdownView = function(){
var b = this;
this.vc =!1;
a(。cs)。on(click,.trans-disabled,function(a){
a.stopPagagation()
}); $(。cs)。on(click,.custom_dd_wrapper,.popup .custom_dd_wrapper,function(){
b.vc =!0;
var f = a (this).closest(。custom_dd_wrapper);
a(f).find(ul)。toggle();
a(f).find(。custom_dd_select)。toggleClass(点击);
a(f).find(。custom_dd_options)。toggleClass(show)
}); (.cs)。on(click,.custom_dd_options .custom_dropdown> li:not(.trans-disabled),
k);
a
if(0> window.navigator.userAgent.indexOf(MSIE)&& null == navigator.userAgent.match(/Trident.*rv\:11\./))a (.cs)。on(blur,.custom_dd_wrapper,.popup .custom_dd_wrapper,function(){
a(this).find(。custom_dd_options ul)。is(:visible )&& g.call(this)
}); $(b.vc)b.vc =!1;
else {
var f = a(。custom_dropdown)。filter(:visible);
0< f.length&& f.each(g);
}
} );
a(。cs)。on(click,.disable,g)
}
})
解决方案
您必须更改
< div class =custom_dd_select>
< span>
< a>讴歌< / a>< / span>
< / div>
至
< div class =custom_dd_select>
< span>
< a>宝马< / a>< / span>
< / div>
这将起作用
So, here's the HTML for a custom dropdown that doesn't use a select tag. The placeholder/default value for the dropdown is "Acura", which is the first element in the list (ul). I'm trying to see if I can change the placeholder/default value for the dropdown (to say, BMW for example) without changing the order of the list of the dropdown (the makes are in alphabetical order).
<span id="builder-make-selection" class="pick">
<span class="label">Make:</span>
<div class="custom-dd-wrapper builder-makes" tabIndex="1">
<div class="custom_dd_select">
<span>
<a>Acura</a></span>
</div>
<div class="custom_dd_options">
<ul class="custom_dropdown">
<li data-make="Acura">Acura</li>
<li data-make="Alfa Romeo">Alfa Romeo</li>
<li data-make="Audi">Audi</li>
<li data-make="BMW">BMW</li>
</ul>
</div>
Here's the javascript that's creating the dropdown:
(function(h, a) {
function k() {
var b = a(this).parents("div.custom_dd_wrapper"),
f = b.attr("id"),
e = a(b).find(".custom_dd_select a"),
l = a(this).data(),
d = e.text().trim(),
g = a(this).text().trim();
"makes-options" == f && (a(b).addClass("active"), e.parent("span").attr("style", a(this).attr("style")));
e.text(g);
for (var m in l) {
if(m=='make'){
e.parent("span").data(m,l[m]);
}
}
d != g && a(this).closest(".custom_dd_wrapper").trigger("change")
}
function g() {
var b = a(this).closest(".custom_dd_wrapper");
a(b).find("ul").hide();
a(b).find(".custom_dd_select").removeClass("click");
a(b).find(".custom_dd_options").removeClass("show")
}
h.CustomDropdownView = function() {
var b = this;
this.vc = !1;
a(".cs").on("click", ".trans-disabled", function(a) {
a.stopPropagation()
});
a(".cs").on("click", ".custom_dd_wrapper, .popup .custom_dd_wrapper", function() {
b.vc = !0;
var f = a(this).closest(".custom_dd_wrapper");
a(f).find("ul").toggle();
a(f).find(".custom_dd_select").toggleClass("click");
a(f).find(".custom_dd_options").toggleClass("show")
});
a(".cs").on("click", ".custom_dd_options .custom_dropdown > li:not(.trans-disabled)",
k);
if (0 > window.navigator.userAgent.indexOf("MSIE ") && null == navigator.userAgent.match(/Trident.*rv\:11\./)) a(".cs").on("blur", ".custom_dd_wrapper, .popup .custom_dd_wrapper", function() {
a(this).find(".custom_dd_options ul").is(":visible") && g.call(this)
});
else a(".cs").on("click", function() {
if (b.vc) b.vc = !1;
else {
var f = a(".custom_dropdown").filter(":visible");
0 < f.length && f.each(g);
}
});
a(".cs").on("click", ".disable", g)
}
})
解决方案
You have to change
<div class="custom_dd_select">
<span>
<a>Acura</a></span>
</div>
to
<div class="custom_dd_select">
<span>
<a>BMW</a></span>
</div>
That will work
