我正在使用AngularJS并在单个html中有许多Bootstrap模式。 由于我需要在访问模态时与周围区域进行交互,因此我设置了:
.modal-backdrop {
display: none;
}
但是,现在我需要添加一个必须有背景的嵌套模态。 我该怎么做?
答案 0 :(得分:0)
你可以确保在第一个模态打开时没有背景(同时)......
在每个data-toggle='modal'
按钮上单击检查它。
$(document).on("click","[data-toggle='modal']",function(){
$(".modal-backdrop").eq(0).css({"display":"none"});
// if more than 1 modal openned.
if($(".modal-backdrop").length>1){
// move backdrop up (in z)
var ZindexBackdrop = parseInt($(".modal-backdrop").eq(0).css("z-index"))+20;
console.log("Backdrop z-index: "+ZindexBackdrop);
$(".modal-backdrop").eq(1).css({"z-index":ZindexBackdrop});
// move modal up (in z)
var ZindexModal = parseInt($(".modal").eq(0).css("z-index"))+20;
console.log("Modal z-index: "+ZindexModal);
$(".modal").eq(1).css({"z-index":ZindexModal});
}
});
要将第二个模态/背景z-index
更改为第一个...以上
你的第二个模态必须 NOT 真正被“嵌套”在第一个模式中
因为如果父母有一个孩子的z-index
,则无法更改。{/ p>
但要获得所需的嵌套效果,请在第一个模态中放置第二个模态触发按钮。
$(document).on("click","[data-toggle='modal']",function(){
$(".modal-backdrop").eq(0).css({"display":"none"});
// if more than 1 modal openned.
if($(".modal-backdrop").length>1){
// move backdrop up (in z)
var ZindexBackdrop = parseInt($(".modal-backdrop").eq(0).css("z-index"))+20;
console.log("Backdrop z-index: "+ZindexBackdrop);
$(".modal-backdrop").eq(1).css({"z-index":ZindexBackdrop});
// move modal up (in z)
var ZindexModal = parseInt($(".modal").eq(0).css("z-index"))+20;
console.log("Modal z-index: "+ZindexModal);
$(".modal").eq(1).css({"z-index":ZindexModal});
}
});
