中断“输入”键与表单提交的关联

Question

I want to detect 'enter' key with respect to form without letting the form being submitted. How do I break this association?

document.forms[0].onkeypress = function (event) {
    e = window.event ? window.event : event;
    if (e.keyCode == 13) {
        //actions to be taken
    }    

}

Though actions inside are taken properly, the page reloads upon completion.

Answer 1

Try to return false at the end of your function. Assuming that you're handling the form submission already in a submit event callback.

Answer 2

Return false from your function:

document.forms[0].onkeypress = function (event) {
    e = window.event ? window.event : event;
    if (e.keyCode == 13) {
        //actions to be taken 

        return false;
    }    
}
