分享为什么load()函数不是在其它函数前执行?

var LGMN = -6;

var LTMN = 30;

var ltn = new Array();
var ltx = new Array();
var lgn = new Array();
var lgx = new Array();
var latDelta = 5;
var lngDelta = 6;
var n = 0;
var m = 0;
function load(){
for(var i=LTMN; i<LTMX; i=i+latDelta){
ltn[n] = i;
ltx[n] = i+latDelta;
for(var j=LGMN; j<=LGMX; j=j+lngDelta){
lgn[m] = j;
lgx[m] = j+lngDelta;
m++;
}
n++;
}
alert("后赋值!"+ltn.length); //------> 4 ????????????????????????
}
function affichager(){
alert("这里先执行!");
document.write(ltn.length); //------->0 ???????????????????????
}
</script>
</head>
<body onload="load()" onunload="GUnload()">
<?php
$k = '<script type="text/javascript"> affichager() </script>';
echo $k;
?>
</body>
</html>
我希望可以先做onload="load()" ,然后再affichager(),不知道该怎样修改程序呢?
请教大家.
