Here's a compact solution, but it may not be as clear as @somethinghere 's:
var path= '/branches/projects/MyTool/MyTool/someOtherFolderOrFile'.split('/'),
paths= [];
path.shift();
while(path.length > 1) {
paths.push((paths[paths.length-1] || '') + '/' + path.shift());
}
alert(paths.join('\r'));Update
Thanks for the comments. Here's a more compact version, which doesn't require splitting or shifting:
var path= '/branches/projects/MyTool/MyTool/someOtherFolderOrFile',
paths= [],
i = 1;
while(i = path.indexOf('/',i)+1) {
paths.push(path.substr(0,i));
}
alert(paths.join('\r'));Update #2
And just for giggles, a third solution, which should be more legible than my others, but still a little slower than @somethinghere 's:
var path= '/branches/projects/MyTool/MyTool/someOtherFolderOrFile',
paths= [],
i;
for(var i = 1 ; i < path.length ; i++) {
if(path[i]==='/') paths.push(path.substr(0,i));
}
alert(paths.join('\r'));
