[英]Switch handle multidimensional array. Unexpected result
so I have a javascript function that pushes a multidimensional array value to a parameter like so: 所以我有一个javascript函数,可以将多维数组值推入类似这样的参数:
function mouseHandle(x,y){
for(var i=0; i<buttonPos.length; i++){
if(x>buttonPos[i][0] && x<buttonPos[i][2]){
if(y>buttonPos[i][1] && y<buttonPos[i][3]){
eventButton(buttonPos[i][4]);
};
};
};
};
This pushed buttonPos[i][4] to the eventButton function which is: 这将buttonPos [i] [4]推送到eventButton函数,该函数是:
function eventButton(d){
switch(d){
case 0: // STARTBUTTON
alert("Button");
break;
default:
alert("NoButton");
};
};
The array is set in the drawButton function as so: 数组在drawButton函数中设置为:
function drawButton(x,y,width,height,string,event){
xCenterButton=x+(width/2);
yCenterButton=y+(height/2);
ctx.fillStyle="rgba(242,255,195,1)";
ctx.fillRect(x,y,width,height);
ctx.rect(x,y,width,height);
ctx.fillStyle="rgba(0,0,0,1)";
ctx.stroke();
ctx.font="25px Arial";
fontSize = getFontSize();
centerNum = fontSize/4;
ctx.fillStyle="rgba(0,0,0,1)";
ctx.textAlign="center";
ctx.fillText(string,xCenterButton,yCenterButton+centerNum);
buttonPos.push([[x],[y],[x+width],[y+height],[event]]);
};
I then call that function in the menuStart function as so: 然后,我在menuStart函数中这样调用该函数:
function menuStart(){
drawButton(getCenterX(100),getCenterY(50),100,50,"Start",0);
};
So the mouseHandle function DOES give the eventButton function a parameter of 0 as expected (I alerted the 'd' parameter within the default case). 因此,mouseHandle函数确实为eventButton函数提供了一个预期的0参数(在默认情况下,我提醒了'd'参数)。 However it's as if the switch statement doesn't recognise the 0 as it uses the default case and alerts 'NoButton'.
但是,就像switch语句无法识别0一样,因为它使用默认大小写并警告“ NoButton”。
Any idea why this is not working? 知道为什么这行不通吗?
