使用JavaScript代码在文本框上触发退格事件

Question

Is it possible to fire backspace event on textbox using javascript? Which should clear the character left to the cursor position. I know that event code for backspace is 8 but I don't know how to fire it using the code.

Solution specific to Internet Explorer 8 would be of great help.

Answer 1

Have a look at this related question: Simulate JavaScript Key Events

Personally, I think it would be a better, cleaner approach to edit the text directly, removing the char before the cursor position. See How to get caret position in textarea

Answer 2

Would be a lot easier to simply trim the value by one character from the end..

var TheTextBox = document.getElementById("id");
TheTextBox.value = TheTextBox.value.substring(0, TheTextBox.length - 1);
