由于该功能执行功能后如何禁用Enter/Return键? [英] How to disable Enter/Return Key After a function is executed because of it?

问题描述

我有此功能，其中#text_comment是文本区域的ID:

I have this function where #text_comment is the ID of a textarea:

$('#text_comment').live('keypress',function (e) {

    if(e.keyCode == 13) {
        textbox = $(this);
        text_value = $(textbox).val();

        if(text_value.length > 0) {
            $(this).prev().append('<div id="user_commenst">'+text_value+'</div>');
            $(textbox).val("");
        } 
    }                                               
});

正在发生的事情是，当按下回车键或回车键(键代码13)时，文本将追加，但是它也将文本向下移动一行，这是按回车键所应该的.

What is happening is the text is appending when the enter/return key is hit (keyCode 13), but it is also moving the text a line down, as the enter/return key is supposed to.

即使我将文本框的值设置为"，也​​会发生这种情况.

This is occurring even though I set the value of the textbox to "".
