我正在将PhoneGap和jQuery Mobile用于移动网络应用。当我尝试运行在onclick属性上设置的MyFunction时,我在控制台中出现错误
未捕获的ReferenceError:未定义MyFunction。
这是我的代码:
<!DOCTYPE html>

return text;
}
function makeid1()
{
var text1 = "";
var possible = "123456789";
for( var i=0; i < 1; i++ )
text1 += possible.charAt(Math.floor(Math.random() * possible.length));
return text1;
}
function makeid2()
{
var text2 = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
for( var i=0; i < 1; i++ )
text2 += possible.charAt(Math.floor(Math.random() * possible.length));
return text2;
}
function makeid3()
{
var text3 = "";
var possible = "123456789";
for( var i=0; i < 2; i++ )
text3 += possible.charAt(Math.floor(Math.random() * possible.length));
return text3;
}
function myFunction()
{
document.getElementById("demo").innerHTML="D01E-BOA0-" + makeid() + "-" + makeid1() + makeid2() + makeid3();
}
</script>

我不确定这会有所帮助,将所有代码打包成文档,并且
使用jQuery处理按钮的click
:
<input type="button" id="generate" value="Generate!" data-theme="b">
$('#generate').on('click', function () {
$("#demo").html("D01E-BOA0-" + makeid() + "-" + makeid1() + makeid2() + makeid3());
});
完整代码:
$(function () {
function makeid() {
var text = "";
var possible = "123456789";
for( var i=0; i < 4; i++ ) {
text += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text;
}
function makeid1() {
var text1 = "";
var possible = "123456789";
for( var i=0; i < 1; i++ ) {
text1 += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text1;
}
function makeid2() {
var text2 = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
for( var i=0; i < 1; i++ ) {
text2 += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text2;
}
function makeid3() {
var text3 = "";
var possible = "123456789";
for( var i=0; i < 2; i++ ) {
text3 += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text3;
}
$('#generate').on('click', function () {
$("#demo").html("D01E-BOA0-" + makeid() + "-" + makeid1() + makeid2() + makeid3());
});
});
检查此FIDDLE以在android上测试它。

这可能会解决您的问题:
为您的身体添加onLoad的监听器:
<body onLoad="fireItUp()">
使用被调用的方法为cordova的设备添加事件监听器:
function fireItUp() {
document.addEventListener("deviceready", onDeviceReady, false);
}
使用回拨方法将您的活动绑定到jquery手机&#39;点击&#39; event(您可能希望为按钮指定id或类,因为这会绑定到所有输入元素,这可能是不受欢迎的):
function onDeviceReady() {
jQuery(input).bind('tap',function(event){
myFunction();
});
}
