停用Enter鍵表單自動提交實作程式碼_javascript技巧

複製程式碼 程式碼如下:

//停用Enter鍵表單自動提交document.on function(event) {
var target, code, tag;
if (!event) {
event = window.event; //針對ie瀏覽器
target = event.srcElement;
code = event.keyCode;
if (code == 13) {
tag = target.tagName;
if (tag == "TEXTAREA") { return true; }
else { return false; }
}
}
else {
target = event.target; //針對遵循w3c標準的瀏覽器，如Firefox
code = event.keyCode;
if (code == 13) {
tag = target.tagName;
if (tag == "INPUT") { return false; }
else { return true; }
}
}
};
