问题 Hey guys, I'm thinking of ways to disable users from typing some special characters like < and >.

问题 I currently have a textarea which I requires control over text that has been pasted in, essentially I need to be able to take whatever the user wants to paste into a textarea and place it into a variable. I will then work out the position in which they pasted the text and the size of the string to remove it from the textarea, Then at the end deal with the text thats is in the variable in my own way.
