一段时间以来，我一直在努力寻找解决方案，但我似乎无法让它发挥作用。
我在做什么: 我正在尝试从我的 php 文件中获取一个数组，以便我可以在我的 javascript 中使用它。
例子.php
$arr = Array(
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(0,0,0,0,0,0,0,0,1,1,1,0,0,0,0,0,0,0,0,0,0,3,3,3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(3,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,3,3,3,3,3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(3,3,3,3,3,3,0,0,0,0,1,0,0,0,0,0,3,3,3,3,3,0,0,3,3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0),
Array(0,3,3,3,3,3,3,0,0,0,1,0,0,0,3,3,3,3,3,0,0,0,0,0,3,3,0,1,1,1,1,1,1,1,0,0,0,0,0,0),
Array(0,0,0,0,0,0,3,3,3,3,1,3,3,3,3,3,0,0,0,0,0,0,0,0,0,3,3,1,3,3,3,3,3,1,1,1,1,0,0,0),
Array(0,0,0,0,0,0,0,3,3,3,1,3,3,3,0,0,0,0,0,0,0,0,0,0,0,0,3,1,3,3,3,3,3,3,3,3,1,0,0,0),
Array(0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,3,3,3,1,1,0,0),
Array(0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,1,1,1,3,3,1,1,1),
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0,0,0,0,0,1,1,3,3,3,3,3,3,3),
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,1,3,3,3,3,3,3,3,3),
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,1,3,3,3,3,3,3,3,3),
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,1,1,3,3,3,3,3,3,3,3),
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,1,1,3,3,3,3,3,3,3,3,3),
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,0,0,0,0,0,1,3,3,3,3,3,3,3,3,3,3),
Array(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,3,3,3,3,3,3,3,3,3,3)
);
echo json_encode($arr);
我用 javascript 函数调用它
function getArray(){
$.ajax({
url: 'Example.php',
success: function(resultarray) {
alert("success " + resultarray);
return levelarray;
},
error: function(xhr, status, error) {
//alert(xhr.responseText);
}
});
}
这个 alert("success "+ resultarray); 确实返回了它应该的数组。
但是当我想在我的 javascript 中使用它时，它一直说它是未定义的，或者它什么也没说。
我试过这样的:
var test = getArray();
alert("result= "+ test);
因此此警报不断返回错误或空值。
有人知道我该怎么做吗？
提前谢谢你。
