parentNode或previousElementSibling在IE8中不起作用 [英] parentNode or previousElementSibling not working in IE8
问题描述
我有一些javascript,并且在IE8中,parentNode或previviousElementSibling似乎都在破坏。该代码在firefox和IE9中运行良好。这是未实现的行:
$(submitter.parentNode.parentNode.previousElementSibling).children('#mark_as_broken' )。显示();
代码类似于
< form>< div>< input id = mark_as_broken>< / input>< / div>< / form>
< form>< div>< input id = mark_as_fixed>< / input>< / div>< / form>
其中mark_as_fixed输入是提交者。这适用于其他浏览器。
任何想法都不起作用,为什么?
previousElementSibling
。

这是一个应该有效的功能。 尚未测试过。似乎工作。
var previousElementSibling = function(el){
if(el.previousElementSibling){
return el.previousElementSibling;
} else {
while(el = el.previousSibling){
if(el.nodeType === 1)return el;
}
}
}
$(previousElementSibling(submitter.parentNode.parentNode))
编辑:
你没有提到jQuery,但你似乎在使用它的API。如果是这样,你可以这样做:
$(提交者).closest('form')。prev()。find ( '#mark_as_broken')显示();
根据您的标记,您似乎应该使用 .find ()
而不是 .children()
。
I have some javascript, and either parentNode or previviousElementSibling seems to be breaking in IE8. The code works fine in firefox and IE9. This is the line that's not getting implemented:
$(submitter.parentNode.parentNode.previousElementSibling).children('#mark_as_broken').show();
code is something like
<form><div><input id=mark_as_broken></input></div></form>
<form><div><input id=mark_as_fixed></input></div></form>
where the mark_as_fixed input is the submitter. This works on other browsers.
any ideas which bit of it won't work, and why?
previousElementSibling
is not supported until IE9.

Here's a function that should work. Haven't tested it yet. Seems to work.
var previousElementSibling = function( el ) {
if( el.previousElementSibling ) {
return el.previousElementSibling;
} else {
while( el = el.previousSibling ) {
if( el.nodeType === 1 ) return el;
}
}
}
$( previousElementSibling(submitter.parentNode.parentNode) )
EDIT:
You didn't mention jQuery, but you appear to be using its API. If so, you can just do this:
$(submitter).closest('form').prev().find('#mark_as_broken').show();
Based on your markup, it appears as though you should be using .find()
instead of .children()
.
