jquery序列化serialize()方法时中文乱码及解决办法
乱码
- 原因:.serialize()自动调用了encodeURIComponent方法将数据编码了
- 解决方法:调用decodeURIComponent(XXX,true);将数据解码
- 例如:
var params = jQuery("#formId").serialize(); // http request parameters. 5 params = decodeURIComponent(params,true);
示例
let str1 = $("#form1").serialize()
str1 = decodeURIComponent(str1,true);
console.log("query_", str1 )
jquery遍历数组的方式
1,for循环:
var arr = new Array(13.5,3,4,5,6);
for(var i=0;i<arr.length;i++){
arr[i] = arr[i]/2.0;
}
2,for,in循环:
var x
var mycars = new Array()
mycars[0] = "Saab"
mycars[1] = "Volvo"
mycars[2] = "BMW"
for (x in mycars)
{
document.write(mycars[x] + "<br />")
}
3,each遍历一维数组:
var arr=new Array();
arr=["aaa","bbb","ccc"];
$.each(arr,function(index,value){
alert(i+"..."+value);
});
4,each遍历二维数组:
$(function () {
$.each([["aaa", "bbb", "ccc"], ["ddd", "eee", "fff"], ["ggg", "hhh", "iii"]], function (index, item) {
alert(index + "..." + item);
//输出0...aaa,bbb,ccc 1...ddd,eee,fff 2...ggg,hhh,iii 这时的index为数组下标,item相当于取这二维数组中的每一个数组
$.each(item, function (index, itemobj) {
alert(index + "....." + itemobj);
});
});
//输出0...aaa,bbb,ccc 0...aaa 1...bbb 2...cccc 1...ddd,eee,fff 0...ddd 1...eee 2...fff 2...ggg,hhh,iii 0...ggg 1...hhh 2...iii
});
