问题描述
如何在以下代码中识别哪个 Ctrl / Shift / Alt 键?
$(#my_id)。click(function(){
if(< left control key pressed> ;){alert(Left Ctrl);}
if(< right shift and left alt keys are pressed>){alert(Right Shift + Left Alt);}
});
解决方案
。微软实现了确定哪个(右/左)键被按下的能力。这里是一个链接 http://msdn.microsoft.com/ en-us / library / ms534630(VS.85).aspx
我还在浏览器中发现了这篇关于按键,按键,按键事件的文章。
http://unixpapa.com/js/key.html
$ $ $ $'code $('#someelement')。bind('click',function(event){
if .ctrlKey){
if(event.ctrlLeft){
console.log('ctrl-left');
}
else {
console.log(' ctrl-right');
}
}
if(event.altKey){
if(event.altLeft){
console.log('alt-left ');
}
else {
console.log('alt-right');
}
}
if(event.shiftKey){
if(event.shiftLeft){
console.log('shift-left');
}
else
{
console.log('右移');
}
}
});
How could I identify which Ctrl / Shift / Alt keys are pressed in the following code ?
$("#my_id").click(function() {
if (<left control key is pressed>) { alert("Left Ctrl"); }
if (<right shift and left alt keys are pressed>) { alert("Right Shift + Left Alt"); }
});
解决方案
Well you this wont work in all browsers just IE 8. Microsoft implemented the ability to determine which (right/left) key was pressed. Here is a link http://msdn.microsoft.com/en-us/library/ms534630(VS.85).aspx
I also found this wonder article about keypress, keyup, keydown event in browsers. http://unixpapa.com/js/key.html
$('#someelement').bind('click', function(event){
if(event.ctrlKey) {
if (event.ctrlLeft) {
console.log('ctrl-left');
}
else {
console.log('ctrl-right');
}
}
if(event.altKey) {
if (event.altLeft) {
console.log('alt-left');
}
else {
console.log('alt-right');
}
}
if(event.shiftKey) {
if (event.shiftLeft) {
console.log('shift-left');
}
else
{
console.log('shift-right');
}
}
});
