我的网页上有一些谷歌地图嵌入;这些使我的页面变慢,所以我想在加载页面后加载它们,所以我尝试这样的东西。不幸的是,地图的iframe源会发生变化,但地图内部没有加载,只是空白。
e.g。链接:
<iframe width="300" height="300" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://maps.google.co.in/maps?f=q&source=s_q&hl=en&geocode=&q=Megarugas+Banquet+and+Lawn,+Opp.+Chandivali+studio,&aq=&sll=19.127228,72.865035&sspn=0.013259,0.022724&ie=UTF8&hq=Megarugas+Banquet+and+Lawn,+Opp.+Chandivali+studio,&hnear=&t=m&cid=15174344858031542989&ll=19.115165,72.894802&spn=0.024329,0.025663&z=14&iwloc=A&output=embed"></iframe><br /><small><a href="https://maps.google.co.in/maps?f=q&source=embed&hl=en&geocode=&q=Megarugas+Banquet+and+Lawn,+Opp.+Chandivali+studio,&aq=&sll=19.127228,72.865035&sspn=0.013259,0.022724&ie=UTF8&hq=Megarugas+Banquet+and+Lawn,+Opp.+Chandivali+studio,&hnear=&t=m&cid=15174344858031542989&ll=19.115165,72.894802&spn=0.024329,0.025663&z=14&iwloc=A" style="color:#0000FF;text-align:left">View Larger Map</a></small>
HTML:
<iframe id="blabla"></iframe>
JS:
$(window).load(function() {
if ($('#blabla').length <= 0) { return; } // to avoid errors in case the element doesn't exist on the page / removed.
$('#blabla').attr('src','//example.com/page');
});
答案 0 :(得分:1)
src不会在脚本中解析,您必须用&
替换&
的所有出现
您无需自行完成此操作。
创建一些元素,将html设置为src,然后检索元素的文本:
$(window).load(function() {
$('#blabla').attr('src',$('<span/>').html('https://example.com/page').text());
});
附加说明:
您不需要检查$('#blabla')
的长度,当jQuery对象为空时,您不会收到错误。
