我如何能够在网页上建立一个电网(10X10),使用户能够点击电网中的任何位置,并用单分机记录(x,y)位置,例如涵盖数值0.0~10.0或0.1-9.9?
感谢!

Use a <canvas>
for the grid, and attach a click/code> 活动听众。
您可使用客户记录点火点。 X和客户 mo物的Y性质:
document.addEventListener( click , function(event){event.clientX;event.clientY;}, false);
以上法典只是一次示范,甚至连双管齐下。 <代码>event.clientX和event.clientY
均持有 mo坐标。
我使用了j Query图书馆。
var boxX = 0;
var boxY = 0;
var box = <div class="box" /> ; // define the .box element
for(var i = 0; i<100;i++){ // create 100 boxes
$( #grid ).append(box);
}
$( .box ).on( click ,function(){
boxX = $(this).position().left;
boxY = $(this).position().top;
$(this).text( X= + boxX + , Y= + boxY);
});
Instead of .position()
(to get the element position from the parent element)
you can use .offset()
to get the element offset from window boundaries.
