Chrome is a minimalist browser so neither it has all those crappy menus nor toolbars. So you need to know exactly where is what to manipulate its features. Now you just need to follow these three steps to disable / enable JS on your Google Chrome. Use my simple screenshots as visual aids to achieve the aim.
Step 1: Locate the Settings Icon
Look at the top right corner of the browser next to the address bar. Refer to the image below. Click on that icon. Then Move down to the Options menu. See the highlight menu option.
Step 2 : Go to Content Settings.
Its sometimes to hard to identify the buttons in the chrome UI. I tend to look at them as text boxes sometimes. Notice the button in Green area. Click that. You will see another window.
Step 3 : Finaly disable JS
