好的,所以我搜索了一下,找不到我的问题的答案。至少没有一个与我的问题完全匹配;所以这里是希望你们没有更好的运气,而且你们其中一个人知道我的问题的答案。
在有人询问之前......是的,我是微软的开发人员,是的,IE是我们的产品,是的,几乎所有开发团队的人都宁愿使用Firefox或Chrome,而不是IE,不......我们无法控制它的运行方式,因为这是Internet Explorer团队的责任。此外,我们不是每个人都让我们成为邪恶的帝国。
话虽这么说,但我会给你一些代码,希望能够尽可能地描绘出最好的画面。
选择下拉列表是一个自定义版本,我通过div标签隐藏了它的默认箭头,并在其背景中包含了我自己的下拉箭头,右侧是一个类右箭头。这些元素通过jQuery动态绑定在一起,这里是jQuery代码......
function loadMarketSelector(options) {
// If the market selector already exists, just make sure it's visible.
if ($('#marketSelectorContainer').show().length) {
return;
}
var settings = { defaultCsvMarket: "", marketLabel: "", addUrl: "", loadingId: "", panelId: "", csvMarketOptions: [] };
if (options) {
$.extend(settings, options);
}
var $select = $('<select>', { id: 'csvMarketSelector', name: 'csvMarketSelector' }).addClass('items');
var defaultCsvMarketLowercase = settings.defaultCsvMarket.toLowerCase();
// Populate the market list
$(settings.csvMarketOptions).each(function (index, element) {
var $option = $('<option>', { title: element.label, text: element.label, dir: element.dir });
$option.data('marketId', element.market);
// If the user hasn't selected a market yet, use the best guess for their current language
if (element.market.toLowerCase() == defaultCsvMarketLowercase) {
$option.attr('selected', true);
$option.attr('class', 'selected');
} else {
$option.attr('class', 'other');
}
$select.append($option);
});
var $marketSelectorContainer = $('<div class="marketCont" id="marketSelectorContainer">').append($('<div class="marketvalue">').append($('<span>', { text: settings.marketLabel })).append($('<div class="marketlist">').append($('<div class="rightarrow hidden">').append($select))));
$('#payment-options-iframehost').before($marketSelectorContainer);
// When the user clicks on a market, refresh the page with the locale set to that market and with the redemption interface already open
$('.marketlist select').bind({
change: function () {
// Reload the page with the language set to the selected market and with the "redeem card" menu already open
var langParam = "lang=" + $(this).find('option:selected').data('marketId');
window.location.hash = 'redeem';
if (!window.location.search) {
window.location.search = langParam;
}
else if (window.location.search.search(/lang=/)) {
window.location.search = window.location.search.replace(/lang=(.+)&?/, langParam);
}
else {
window.location.search += '&' + langParam;
}
},
click: function(e){
$(this).parents('.rightarrow').toggleClass('downarrow');
//Once the select box is clicked collect the options right and left offsets.
var leftPos = $(this).offset().left;
var rightPos = leftPos + $(this).width();
//After the select box is clicked, if the mouse moves outside of the left and right positions;
//deactivate the dropdown box and return the sprite to it's original position.
$(document).mousemove(function(e){
if (e.pageX < leftPos-10 || e.pageX > rightPos+10) {
$('.marketlist select').trigger('blur');
}
})
},
blur: function () {
if ($(this).parent().hasClass('downarrow')) {
$(this).parent().removeClass('downarrow');
}
}
});
var mkt = $('.marketlist select option.selected').data('marketId'),
iframeId = settings.panelId + " iframe";
if (typeof mkt !== "undefined") {
// If the market passed to the page (via the lang param or the browser language) is CSV supported, load the PCS iframe
bam.ui.loadIframe(iframeId, appendParameters(settings.redeemCardUrl, { lmkt: mkt, mkt: mkt }), settings.loadingId, true, function () { $('.rightarrow').show();});
}
else {
// If the market is not supported, hide the description text but don't load PCS (since it won't work). The selector will be blank by default.
$(iframeId).hide();
}
}
这是适用于每个元素的css ......

如果我直接点击选择框,语义选择框在所有浏览器中都能正常工作。问题是当我点击IE中的自定义箭头时,它就好像它正在放下列表(即:箭头从右箭头变为向下箭头,选择框高亮显示)(参见IE图像)但是下拉列表框就像隐藏在其他元素后面一样。
其他表单元素位于iframe中,其中国家/地区下拉列表不是。
点击箭头可以在firefox中运行...
适用于Chrome ...
点击IE中的箭头
但点击选择框本身确实有用......
答案 0 :(得分:0)
我现在在几个项目中遇到同样的问题但找不到答案,所以我决定让IE浏览器使用默认的下拉箭头。如果您已经有一个仅IE样式表(如果没有阅读本文关于条件样式的最佳实践 - http://www.paulirish.com/2008/conditional-stylesheets-vs-css-hacks-answer-neither/),那么您可以只在那里定位箭头,并告诉它不要显示:
.payment-options-page .marketlist .rightarrow {display: none;}
结果可能看起来不太完美,但它至少可以正常运行。从我可以告诉其他浏览器忽略重叠元素,无论出于何种原因,IE注册此元素并且不允许点击工作,并且不能通过抵消任一元素的'z-index'来修复。
修改的
多一点搜索,我找到了原因。 IE不支持pointer-events: none
- 这是你需要应用于箭头的css属性,让浏览器知道它应该被忽略。有关详细信息,请参阅此答案:https://stackoverflow.com/a/17441921/2539808
我仍然在寻找这个问题的解决方案,如果我找到一个可以正常运行但仍然按照我们想要的方式运行的话,我一定会告诉你的。)
