Replacing a tab with a different one using JS-CodePudding

Currently, I have something in place that opens a new tab with some html code, using

    const winUrl = URL.createObjectURL(new Blob([final_file], { type: "text/html;charset=utf8" }));
    const win = window.open(winUrl);

where final_file is some html that I generate. I want to make it so instead of opening a new tab every time, if such a tab is already open, it should replace it. I tried using frame names in window.open, but I was told that they are deprecated and shouldn't be used. What do I do?

CodePudding user response：

You should place dedicated window name (target as second argument to .open) to your opened window, so browser would know to replace it instead of opening new window:

    const winUrl = URL.createObjectURL(new Blob([final_file], { type: "text/html;charset=utf8" }));
    const win = window.open(winUrl, 'my-window');

target is not deprecated.
