JS共用方法 - 转码/doAjax

1、

//字符串转换：
$.get(
		'/showswf/saveSwf.html',
		{
			strSwfName : encodeURIComponent(strSwfName),
			strWatchword : encodeURIComponent(strWatchword),
			strUrl : strUrl,
			idd : Math.random()
		},
		function(data) {
		
		}
	)
	
前台：strWatchword : encodeURIComponent(strWatchword),	
后台：strWatchword = URLDecoder.decode(strWatchword,"UTF-8");


//加随机数：	
$.get('/showswf/checkUpload.html?iddd='+Math.random(),
		function(data) {

	});

<script src="../js/showcomment/showcomment.js?v=9"></script>
	
	
//JS判断ID是否存在：
if( document.getElementById("div2") )
   alert("div2存在")
else
   alert("div2不存在");

 

//jquery  ajax 封装
function doAjax(url,data,callBack){
	$.ajax({ 
        type:"POST",
        url: url,
        data: data+"&iddd="+Math.random(),
        dataType: "html",
        success: function(data){ 
        	callBack(data); 
        }
    });
}

function doPostAjax(url,callBack){
	$.post(url, function(data) {
		callBack(data); 
	});
}

function doJsonAjax(url,data,callBack){
	$.ajax({ 
        type:"POST",
        url: url,
        data: data+"&iddd="+Math.random(),
        dataType: "json",
        success: function(data){
        	callBack(data); 
        },
        error: function (data){
        	
        }
    });
}

//拼接字段值-
function spliceFields(arrayField){
	var str = '';
	var value = '';
	for(var i=0;i<arrayField.length;i++){
		value = $("#"+arrayField[i]).val();
		if(value==undefined){
			value = '';
		}
		str += "&"+arrayField[i]+"="+value;
	}
	return str;
}

function spliceCheckboxFields(arrayField){
	var str = '';
	for(var i=0;i<arrayField.length;i++){
		if($("#"+arrayField[i]).attr("checked")==true){
			str += "&"+arrayField[i]+"=1";
		}else{
			str += "&"+arrayField[i]+"=0";
		}
	}
	return str;
}

function spliceRadioFields(arrayField){
	var str = '';
	var value = '';
	for(var i=0;i<arrayField.length;i++){
		value = $('input[name=\"'+arrayField[i]+'\"]:checked').val();
		str += "&"+arrayField[i]+"="+value;
	}
	return str;
}



spliceFields
doAjax(url,data,saveSuccess)	


使用：
var arrayTextField = ['strAwardName','nCount','nPreCount','nStartNumber'];

function saveAward(){
	var id = $("#id").val();
	if(id != ''){
		var url = "/activity/saveEditAward.do";
		var data = spliceFields(arrayTextField);
		data += "&nActivityId="+nActivityId;
		data += "&id="+id;
	}else{
		var url = "/activity/saveAward.do";
		var data = spliceFields(arrayTextField);
		data += "&nActivityId="+nActivityId;
	}
	doAjax(url,data,saveSuccess);
}
