javascript - How do I search through scope variables in Google Chrome Developer Tools?

Question

I set a breakpoint in a javascript function with Google Chrome Developer Tools.

I am looking for a variable in the scope variables of the function with the value "Fred." How do I search for this value amongst the variables within the scope of the function?

You'll need to add a script to the console so that you can actually perform a search, as the Developer Tools don't allow for this by default. Here's that function for you (See my Gist comment below for an update):

function scanScope(whatToScan, scanValue) {
for (var key in whatToScan) {
if (whatToScan[key] == scanValue) {
console.log(key + ' = ' + whatToScan[key]); 
} else {
if( (typeof whatToScan[key] === "object") && (key !== null) ) { 
scanScope(whatToScan[key], scanValue);
}
}
}
}
