請問想要合併兩個function成一個function，
並且function()裡可帶這兩個參數
請問要怎麼寫呢?

讓寫入和讀取的command指令可以寫在一個function裡頭

//寫入save字串到login.txt
function savewrite()
{

//write
   var ReturnString = "";
	var ipAddress = location.protocol+"//"+location.hostname+"/cgi-bin/";
	var URLs = ipAddress + "PProduceXml.php";

var ss = "echo -n \"save"+"\" > /app/Web/cgi-bin/login.txt";
//alert("write:"+ss);

//var URLs = ipAddress + "Command.cgi";
	$.ajax(
		{
		url: URLs,
		data:"Action=TransmissionStart&submitString="+ss,
		type:"GET",
		async: false,
		cache:false,
		success: function(msg)
		{
//alert("msg:"+msg);

		},
		error:function(xhr, ajaxOptions, thrownError)
		{
//alert("xhr:"+xhr+" ajaxOptions:"+ajaxOptions+" thrownError:"+thrownError);
		}
	});
	
	return ReturnString;
}

//讀取login.txt
function loginread()
{

        var ReturnString = "";
	var ipAddress = location.protocol+"//"+location.hostname+"/cgi-bin/";
	var URLs = ipAddress + "PProduceXml.php";

        var ss = "cat /app/Web/cgi-bin/login.txt";

$.ajax(
		{
		url: URLs,
		data:"Action=TransmissionStart&submitString="+ss,
		type:"GET",
		async: false,
		cache:false,
		success: function(msg)
		{
alert("msg:"+msg);
ReturnString = msg;
		},
		error:function(xhr, ajaxOptions, thrownError)
		{
//alert("xhr:"+xhr+" ajaxOptions:"+ajaxOptions+" thrownError:"+thrownError);
		}
	});

	return ReturnString;
}

問問你家的 PProduceXml.php 支不支援啊...還有看到這種寫法我都快昏倒了, 都不怕被串改命令攻擊的?

最佳解答

參考看看吧!

function readOrWrite(isRead)
{
	var ReturnString = "";
	var ipAddress = location.protocol+"//"+location.hostname+"/cgi-bin/";
	var URLs = ipAddress + "PProduceXml.php";

	// 切換指令字串
	var ss = (!!isRead) ? "cat /app/Web/cgi-bin/login.txt" : "echo -n \"save"+"\" > /app/Web/cgi-bin/login.txt";

	$.ajax(
	{
		url: URLs,
		data: "Action=TransmissionStart&submitString="+ss,
		type: "GET",
		async: false,
		cache: false,
		success: function(msg)
		{
			alert("msg:"+msg);
			if(!!isRead) ReturnString = msg; // 輸入參數為trusy才assign msg給ReturnString
		},
		error:function(xhr, ajaxOptions, thrownError)
		{
			//alert("xhr:"+xhr+" ajaxOptions:"+ajaxOptions+" thrownError:"+thrownError);
		}
	});

	return ReturnString;
}
