Bookmarklet to run js

I have been trying to create a bookmarklet to run quick javascript, and am having trouble doing so. I have tried 

javascript:var runjs = prompt("Enter JS:");function runjs() {runjs};
Solution

  • it seems you want to do the following

    javascript:eval(prompt("Enter JS:"));

    this will evaluate (run) the code entered in the prompt

    as per comment

    javascript:try{eval(prompt("Enter JS:"));}catch(e){alert(e);}

    this will catch most? errors
