jquery keypress event for cmd+s AND ctrl+s
提问by John Magnolia
Using one of the examples from a previous question I have:
使用上一个问题中的一个示例，我有：
$(window).keypress(function(event) {
if (!(event.which == 115 && event.ctrlKey) && !(event.which == 19)) return true;
$("form input[name=save]").click();
event.preventDefault();
return false;
});
Is it also possible to change this to work for the Mac cmd key?
是否也可以将其更改为适用于 Mac cmd 键？
I have tried (!(event.which == 115 && (event.cmdKey || event.ctrlKey)) && !(event.which == 19))but this didn't work.
我试过了，(!(event.which == 115 && (event.cmdKey || event.ctrlKey)) && !(event.which == 19))但这没有用。

Use the event.metaKeyto detect the Command key
使用event.metaKey检测 Command 键
$(document).keypress(function(event) {
if (event.which == 115 && (event.ctrlKey||event.metaKey)|| (event.which == 19)) {
event.preventDefault();
// do stuff
return false;
}
return true;
});

For detecting ctrl+sand cmd+s, you can use this way:
对于检测ctrl+sand cmd+s，您可以使用这种方式：
jQuery:
jQuery：
var isCtrl = false;
$(document).keyup(function (e) {
if(e.which == 17) isCtrl=false;
}).keydown(function (e) {
if(e.which == 17) isCtrl=true;
if(e.which == 83 && isCtrl == true) {
alert('you pressed ctrl+s');
return false;
}
});

This works for me:
这对我有用：
$(document).keypress(function(event) {
if ((event.which == 115 || event.which == 83) && (event.ctrlKey||event.metaKey)|| (event.which == 19)) {
event.preventDefault();
// do stuff
return false;
}
return true;
});
