window.event.keyCode我如何解决这个问题？Firefox不支持event.keycode。在firefox中使用event.which
function checkKey(evt) {
var keyID = (evt.charCode) ? evt.charCode : ((evt.which) ? evt.which : evt.keyCode);
alert(keyID);
}
当我在做一个项目时，我遇到了同样的问题。我做了一些
RNDe.keyCodeonkeydown（）// HTML (Note onkeydown() function here)
<input id="anyId" onkeydown="return myFunction(event)" type="text" />
// JavaScript for it
function myFunction(e) {
var asciiValue = e.keyCode ;
alert ("ASCII Value: " + asciiValue ); // ASCII of pressed key
if(asciiValue >0){
return true;
}
else{
return false;
}
}
对不起，它不起作用。。。它实际上停止了对IE=（仍然没有成功…我感谢你的帮助…对IE的帮助…虽然我在调用该方法时指定了这一点…checkKey（这）在文本框中…是否正确？不，按control键绑定
<input type="text" onkeypress="return key_fir(event);" name="name" id="login_email">
function key_fir(e)
{
e = e || window.event || {};
var charCode = e.charCode || e.keyCode || e.which;
if (charCode == 13) {
//write your code here Like $("#log_sub").click();
}
}
// HTML (Note onkeydown() function here)
<input id="anyId" onkeydown="return myFunction(event)" type="text" />
// JavaScript for it
function myFunction(e) {
var asciiValue = e.keyCode ;
alert ("ASCII Value: " + asciiValue ); // ASCII of pressed key
if(asciiValue >0){
return true;
}
else{
return false;
}
}
// HTML (Note onkeypress() function here)
<input id="anyId" onkeypress="return myFunction(event)" type="text" />
// JavaScript for it
function myFunction(e) {
var asciiValue = e.keyCode || e.charCode ; // It'll handle both Chrome & Firefox
alert ("Ascii Value: " + asciiValue); // ASCII of pressed key
if(asciiValue>0){
return true;
}
else{
return false;
}
}
