keypress event not generated in Chrome on ENTER Key?
提问by emilly
My application requires an input from users, on entering a value in a textbox, users hit Enter (Return Key) and this calls a buttons onclick event. This works fine in IE, FF but not Chrome. On enter in chrome, keypress event is not generated Here is my code snippet
我的应用程序需要用户输入，在文本框中输入值时，用户按 Enter（回车键），这会调用按钮 onclick 事件。这适用于 IE、FF，但不适用于 Chrome。在 chrome 中输入时，不会生成按键事件这是我的代码片段
$('#myDiv').keypress(function (e) {
alert("Key pressed");
if (e.keyCode == $.ui.keyCode.ENTER) {
alert("enter pressed");
}
});
Could anyone provide input on this?
任何人都可以提供这方面的意见吗？

Cross-browsers method :
跨浏览器方法：
$('#myDiv').keydown( function(e) {
var key = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
if(key == 13) {
e.preventDefault();
alert("enter pressed");
}
});

keypressis the correct event for detecting which character has been typed (although in this particular case, that of detecting the enter key, keydownwould work just as well). However, how to get the character typed in a keypress event is inconsistent between browsers, so jQuery normalizes on the whichproperty. Here's what you want:
keypress是检测输入了哪个字符的正确事件（尽管在这种特殊情况下，检测回车键的事件keydown也能正常工作）。但是，如何获取 keypress 事件中键入的字符在浏览器之间是不一致的，因此 jQuery 对which属性进行了规范化。这是你想要的：
$('#myDiv').keypress(function (e) {
alert("Key pressed");
if (e.which == $.ui.keyCode.ENTER) {
alert("enter pressed");
}
});

alert("Key pressed");
if (e.keyCode == $.ui.keyCode.ENTER) {

}
});

Chrome seems to be working with ENTERkey and not 13.
Chrome 似乎正在使用ENTERkey 而不是13.
this works for me on all browsers including CHROME.
这适用于所有浏览器，包括CHROME.
$('#myDiv').keydown(function(e) {
if ((e.which == 13) || (e.which == keyCode.ENTER)) {
alert("enter pressed");
}
