Page Specific Javascript in Ruby on Rails
:
Thanks, this is great. I added a couple functions to the init.js file in my project to make the syntax shorter, hope that it helps someone:
```
#init.js
var Page, bind = function(fn, me){ return function(){ return fn.apply(me, arguments); }; };
Page = (function() {
function Page() {
this.action = bind(this.action, this);
this.controller = bind(this.controller, this);
}
Page.prototype.controller = function() {
return $('meta[name=psj]').attr('controller');
};
Page.prototype.action = function() {
return $('meta[name=psj]').attr('action');
};
Page.prototype.isController = function(controller) {
return controller === this.controller()
};
Page.prototype.isAction = function(action) {
return action === this.action()
};
Page.prototype.isControllerAndAction = function(controller, action) {
return this.isController(controller) && this.isAction(action)
};
return Page;
})();
this.page = new Page;
```
So then you can do the check like this like this:
``` if(!page.isControllerAndAction('users', 'index')) return;```
