Change link target attribute if its href attribute contains certain phrase
提问by FoxKllD
I am trying to check all anchors' tags using .each()and set home URLs' target to _selfand other non-home URLs' target to _blank.
我正在尝试使用检查所有锚点的标签.each()并将主 URL 的目标设置为 ，_self并将其他非主 URL 的目标设置为_blank。
So far, I got this:
到目前为止，我得到了这个：
$('a').each(function() {
var homeURL = 'google.ca';
if ( $(this+'[href*='+homeURL+']')) {
$(this).attr('target','_self');
}else{
$(this).attr('target','_blank');
}
});
This is also on jsBin here.
这也是上jsBin这里。
For some reason, the non-home URLs set to target="_self". Can anyone explain why?
出于某种原因，非主 URL 设置为target="_self". 谁能解释为什么？

Try this instead:
试试这个：
if($(this).is("[href*=" + homeURL + "]")){
$(this).attr('target','_self');
} else {
$(this).attr('target','_blank');
}
is()returns trueif the selected element matches the selector in the function and falseif it does not. So, if the current link's hrefattribute containsgoogle.ca, it'll change its targetattribute to _self. Otherwise, it'll set it to _blank.
is()true如果所选元素与函数中的选择器匹配，则返回，如果不匹配false。因此，如果当前链接的href属性包含google.ca，它会将其target属性更改为_self。否则，它会将其设置为_blank.
And, in fact, for more efficiency, you should cache $(this):
而且，事实上，为了提高效率，您应该缓存$(this)：
var $this = $(this);
if($this.is("[href*=" + homeURL + "]")){
$this.attr('target','_self');
} else {
$this.attr('target','_blank');
}

var homeURL = 'google.ca';
$('a').each(function() {
$(this).attr('target', (this.href.match( homeURL )) ? '_self' :'_blank');
});

You can also achieve this with:
您还可以通过以下方式实现：
$(document).ready(function() {
$("a[href^='http']").attr('target','_blank');
});
