blocks|key|5299059|text|使用window.open()需要注意的一点是，如果您传递给它的url前面没有http://或https://，angular会将其视为路由。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5299060|要解决此问题，请测试url是否以http://或https://开头，如果不是，则追加url。|5299061|let+url:+string+=+'';

One caveat on using <code>window.open()</code> is that if the url that you pass to it doesn't have <code>http://</code> or <code>https://</code> in front of it, angular treats it as a route.

To get around this, test if the url starts with <code>http://</code> or <code>https://</code> and append it if it doesn't.

<pre><code>let url: string = '';
if (!/^http[s]?:\/\//.test(this.urlToOpen)) {
 url += 'http://';
}

url += this.urlToOpen;
window.open(url, '_blank');
</code></pre>

blocks|key|3881957|text|另一种可能的解决方案是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3881958|const+link+=+document.createElement('a');
link.target+=+'_blank';
link.href+=+'https://www.google.es';
link.setAttribute('visibility',+'hidden');

Another possible solution is:

<pre><code>const link = document.createElement('a');
link.target = '_blank';
link.href = 'https://www.google.es';
link.setAttribute('visibility', 'hidden');
link.click();
</code></pre>

blocks|key|3882016|text|我们可以在新的标签页中使用目标=空白来打开|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3882017|+<a+href="https://www.google.co.in/"+target="blank">click+Here+</a>|code-block|syntax|javascript|3882018|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

we can use target = blank to open in new tab

<pre><code> &lt;a href="https://www.google.co.in/" target="blank"&gt;click Here &lt;/a&gt;

you can do like this in your typescript code

<pre><code>onNavigate(){
var location="https://google.com",
}
</code></pre>

In your html code add an anchor tag and pass that variable(location)

<pre><code>&lt;a href="{{location}}" target="_blank"&gt;Redirect Location&lt;/a&gt;
</code></pre>

Suppose you have url like this <code>www.google.com</code> without <code>http</code> and you are not getting redirected to the given url then add <code>http://</code> to the <code>location</code> like this

<pre><code>var location = 'http://'+ www.google.com
</code></pre>

blocks|key|1508279|text|我想与你分享另一个解决方案，如果你有绝对的部分在URL|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1508280|使用${_spPageContextInfo.webAbsoluteUrl}的SharePoint解决方案|offset|length|style|CODE|1508281|HTML：|1508282|<button+(click)="onNavigate()">Google</button>|code-block|syntax|javascript|1508283|TypeScript：|1508284|onNavigate()

I want to share with you one more solution if you have absolute part in the URL 

SharePoint solution with <code>${_spPageContextInfo.webAbsoluteUrl}</code>

HTML:

<pre><code>&lt;button (click)="onNavigate()"&gt;Google&lt;/button&gt;
</code></pre>

TypeScript:

<pre><code>onNavigate()
{
 let link = `${_spPageContextInfo.webAbsoluteUrl}/SiteAssets/Pages/help.aspx#/help`;
 window.open(link, "_blank");
}
</code></pre>

and url will be opened in new tab.

blocks|key|1503852|text|var+url+=+"https://yourURL.com";

++++win.opener+=+null;
++++win.focus();|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|1503853|这将解决问题，在这里您不需要使用DomSanitizer。这对我来说很有用|unstyled|1503854|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|J|8|@]|9|@]|A|$]]|$1|G|3|-4|5|F|7|K|8|@]|9|@]|A|$]]]|H|$]]

<pre><code>var url = "https://yourURL.com";
var win = window.open(url, '_blank');
 win.opener = null;
 win.focus();

This will resolve the issue, here you don't need to use DomSanitizer. Its work for me

in HTML: 

<pre><code>&lt;a class="main-item" (click)="onNavigate()"&gt;Go to URL&lt;/a&gt;
</code></pre>

OR

<pre><code>&lt;button class="main-item" (click)="onNavigate()"&gt;Go to URL&lt;/button&gt;

in TS file:

<pre><code>onNavigate(){
 // your logic here.... like set the url 
 const url = 'https://www.google.com';
 window.open(url, '_blank');

</code></pre>

blocks|key|1503880|text|为了更全面地解决这个问题，这里有另一种使用指令的方法|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1503881|import+{+Directive,+HostListener,+ElementRef+}+from+"@angular/core";

@Directive({
++selector:+"[hrefExternalUrl]"

export+class+HrefExternalUrlDirective+{
++constructor(elementRef:+ElementRef)+{}

++@HostListener("click",+["$event"])
++onClick(event:+MouseEvent)+{

++++let+url:+string+=+(<any>event.currentTarget).getAttribute("href");

++++if+(url+&&+url.indexOf("http")+===+-1)+{
++++++url+=+`//${url}`;
++++}

++++window.open(url,+"_blank");
++}
}|code-block|syntax|javascript|1503882|然后它就像这样使用它一样简单：|1503883|<a+[href]="url"+hrefExternalUrl>+Link+</a>|1503884|别忘了在你的模块中声明指令。|1503885|entityMap^0|L|2|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|W|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|Y|8|@]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|R|$]]

To solve this issue more globally, here is another way using a directive:

<pre><code>import { Directive, HostListener, ElementRef } from "@angular/core";

@Directive({
 selector: "[hrefExternalUrl]"
})
export class HrefExternalUrlDirective {
 constructor(elementRef: ElementRef) {}

 @HostListener("click", ["$event"])
 onClick(event: MouseEvent) {
 event.preventDefault();

 let url: string = (&lt;any&gt;event.currentTarget).getAttribute("href");

 if (url &amp;&amp; url.indexOf("http") === -1) {
 url = `//${url}`;
 }

 window.open(url, "_blank");
 }
}
</code></pre>

then it's as simple as using it like this:

<pre><code>&lt;a [href]="url" hrefExternalUrl&gt; Link &lt;/a&gt;
</code></pre>

and don't forget to declare the directive in your module.

I'm trying to Open a new page when user clicks on a link. I can't use Angular 2 Router, because it doesn't have any functionalities to redirect to an external URL.

so, i'm using window.location.href="...";

html code:

<pre><code>&lt;button (click)="onNavigate()"&gt;Google&lt;/tn-submenu-link&gt;
</code></pre>

typescript code:

<pre><code>onNavigate(){
 //this.router.navigateByUrl("https://www.google.com");
 window.location.href="https://www.google.com";
 }
</code></pre>

But how can I open it in a new tab? when using window.location.href ?
