我的代码就像
var shapes1 = [ r.image("node.gif",190, 100, 47, 45)];
var shapes2 =[];
for (var i = 0, ii = shapes1.length; i < ii; i++) {
shapes1[i].mousedown(function(e){
var temp=this.clone();
shapes1.push(temp);
//now I want to remove "this" from shapes1
//and put it into shape2
//HOW??
isDrag=true;
e.preventDefault();
});
}
也许这是错误的方法?我应该改用一个类,但是不是用于DOM项目吗?
最佳答案
我发现有这样的事情很方便
function removeIf(arr, predicate) {
for (var i = 0; i < arr.length; i++) {
if (predicate(arr[i])) {
arr.splice(i--, 1);
}
}
}
因此:
var shapes1 = [ r.image("node.gif",190, 100, 47, 45)];
var shapes2 =[];
for (var i = 0, ii = shapes1.length; i < ii; i++) {
shapes1[i].mousedown(function(e){
var temp=this.clone();
shapes1.push(temp);
removeIf(shapes1, function (item) { return item === this; });
shapes2.push(this);
isDrag=true;
e.preventDefault();
});
}
