Window.name

Gets/sets the name of the window's browsing context.

Syntax

string = window.name;
window.name = string;

Example

<script>
    // Open a tab with a specific browsing context name
    const otherTab = window.open("url1", "_blank");
    if (otherTab)
        otherTab.name = "other-tab";
</script>
<a href="url2" target="other-tab">This link will be opened in the other tab.</a>

Notes

The name of the window is used primarily for setting targets for hyperlinks and forms. Browsing contexts do not need to have names.

It has also been used in some frameworks for providing cross-domain messaging (e.g., SessionVars and Dojo's dojox.io.windowName) as a more secure alternative to JSONP. Modern web applications hosting sensitive data should, however, not rely on window.name for cross-domain messaging but instead utilize the postMessage API.

window.name will convert all values to their string representations by using the toString method.
