1.数租去重
<script>
var arr1 = [1, 2, 2, 2, 3, 3, 3, 4, 5, 6],
arr2 = [];
for(var i = 0, len = arr1.length; i < len; i++) {
if(arr2.indexOf(arr1[i]) < 0) {
arr2.push(arr1[i]);
}
}
document.write(arr2)
</script>
2.数组排序
<script>
var array = [1, 4, -8, -3, 6, 12, 9, 8];
//排序函数
function compare(val1, val2) {
return val1 - val2;
};
array.sort(compare);
document.write(array);
</script>
3.数组字符串的转换
<script>
//数组转字符串
var a, b;
a = new Array(0, 1, 2, 3, 4);
b = a.join("-"); //"0-1-2-3-4"
//字符串转数组
var s = "abc,abcd,aaa";
ss = s.split(","); // 在每个逗号(,)处进行分解 ["abc", "abcd", "aaa"]
var s1 = "helloworld";
ss1 = s1.split(''); //["h", "e", "l", "l", "o", "w", "o", "r", "l", "d"]
</script>
4.浏览器内核
<div>
<p>IE: trident内核 </p>
<p>Firefox：gecko内核 </p>
<p>Safari：webkit内核 </p>
<p>Opera：以前是presto内核，Opera现已改用Google Chrome的Blink内核 </p>
<p>Chrome：Blink(基于webkit，Google与Opera Software共同开发)</p>
</div>
5.获取当前日期
今天是：
<script type="text/javascript">
var d, s = "";
var x = new Array("星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六");
d = new Date();
s += d.getFullYear() + "年" + (d.getMonth() + 1) + "月" + d.getDate() + "日 ";
s += x[d.getDay()];
document.writeln(s);
</script>
