我只想在我的模态弹出窗口打开时为主体添加样式。之后,当模态弹出窗口关闭时需要删除它。我刚试过这段代码。但根本不工作。
if( $('.modal').hasClass('in') === true ) {
$('body').style({ 'overflow': "hidden" });
}
这是小提琴

使用以下命令修改init对话框的代码:
$(elm).dialog({
...
, open: function() { $("body").css({ "overflow":"hidden" }); }
, close: function() { $("body").css({ "overflow":"" }); }
});

您可以尝试事件shown.bs.modal
和hidden.bs.modal
。此外,您使用了错误的函数style
,您需要将其更改为css
。
$('#myModal').on('shown.bs.modal', function(){
$('body').css({ 'overflow': "hidden" });
}).on('hidden.bs.modal', function(){
$('body').css({ 'overflow': "auto" });
});
$('#myModal').on('shown.bs.modal', function(){
$('body').css({ 'overflow': "hidden" });
}).on('hidden.bs.modal', function(){
$('body').css({ 'overflow': "auto" });
})

您可以使用bootstrap模态事件。 https://getbootstrap.com/docs/3.3/javascript/#modals-events
$('.modal').on('shown.bs.modal', function (e) {
$('body').style({ 'overflow': "hidden" });
})
答案 3 :(得分:0)
我建议您不要使用JavaScript更改CSS,而是建议您使用HTML类:
var $body = $('body');
$('#myModal').on({
'show.bs.modal': function() { $body.addClass('visible') },
'hide.bs.modal': function() { $body.removeClass('visible') }
});
和CSS:
body {
transition: .5s background;
}
body.visible {
background: red;
}
这是jFiddle。
