Navigate to new url from SPFX in Sharepoint online - sharepoint-online

Question

I have a dropdown in SPFX webpart in sharepoint online. In that dropdown, onchange, I am constructing a url with # tag.
E.x. https://sharepointonine/default.aspx#2349-234234-23434
I need to navigate to this new url. I am not sure how to accomplish things.
I have tried:
window.location = url //Gives error that string is not assignable to Location
window.location.href= url//does not reload the page
window.open(url, "_self")//does not reload the page
window.location.assign(url);//does not reload the page
window.location.replace(url);//does not reload the page
Any help?

Answer 1

You can create element 'a' and call click to open url
let a = document.createElement('a');
a.href = 'your link to open';
a.click();
this works fine.
Also you can use react-router, as describe here
There are also redirect link:
import { Redirect } from 'react-router';
When you need to redirect to som url, you render redirect:
<Redirect to={'/to url'}></Redirect>

Answer 2

I test with no framework SPFX.
Test result:
Test code for your reference:
public render(): void {
this.domElement.innerHTML = `
<div class="${styles.noframeworkSpfx}">
<div class="${styles.container}">
<div class="${styles.row}">
<div class="${styles.column}">
<span class="${styles.title}">Welcome to SharePoint!</span>
<p class="${styles.subTitle}">Customize SharePoint experiences using Web Parts.</p>
<p class="${styles.description}">${escape(this.properties.description)}</p>
<a href="https://aka.ms/spfx" class="${styles.button}">
<span class="${styles.label}">Learn more</span>
</a>
<select id="option" >
<option value="test1">test1</option>
<option value="test2">test2</option>
<option value="test3">test3</option>
</select>
</div>
</div>
</div>
</div>`;
this.domElement.querySelector('#option').addEventListener('change', (e) => {
window.location.href="https://www.google.com/search?q="+e.target["value"]
})
}
