我需要为输入来自html表单的JSON请求创建数据。我想要生成的数据格式如下所示。使用javascript创建JSON请求数据
{
"applicationName":"Tesing",
"cpuCount":"12",
"hostdescName":"localhost",
"maxMemory":"0",
"maxWallTime":"0",
"minMemory":"0",
"nodeCount":"1",
"processorsPerNode":"12",
"serviceDesc":{
"inputParams":[
{
"dataType":"input",
"description":"my input",
"name":"myinput",
"type":"String"
},
{
"dataType":"input",
"description":"my input",
"name":"myinput",
"type":"String"
}
],
"outputParams":[
{
"dataType":"output",
"description":"my output",
"name":"myoutput",
"type":"String"
},
{
"dataType":"output",
"description":"my output",
"name":"myoutput",
"type":"String"
}
]
}
}
我的代码如下所示;
var jasonRequest = {};
jasonRequest["applicationName"] = appName;
jasonRequest["cpuCount"] = cpuCount;
jasonRequest["hostdescName"] = hostName;
jasonRequest["maxMemory"] = maxMemory;
jasonRequest["maxWallTime"] = ""; //TODO
jasonRequest["minMemory"] = ""; //TODO
jasonRequest["nodeCount"] = nodeCount;
jasonRequest["processorsPerNode"] = ""; //TODO
var inArray = new Array();
for(var j=0; j<inputCount; j++) {
var input = {};
input["dataType"] = "input";
input["description"] = "empty";
input["name"] = $("#inputName" + j+1).val();
input["type"] = $("#inputType" + j+1).val();
inArray[j] = input;
}
var outArray = new Array();
for(var j=0; j<outputCount; j++) {
var output = {};
output["dataType"] = "output";
output["description"] = "empty";
output["name"] = $("#outputName" + j+1).val();
output["type"] = $("#outputType" + j+1).val();
outArray[j] = output;
}
var serviceDesc = {};
serviceDesc["inputParams"] = inArray;
serviceDesc["outputParams"] = outArray;
jasonRequest["serviceDesc"] = serviceDesc;
alert("printing inArray");
alert(inArray.toSource().toString());
alert(JSON.stringify(jasonRequest));
此代码创建的数据如下。我可以使用字符串并通过连接创建消息，但我认为这不是一个很好的方法。正如你所看到的inputParams和outputParams没有正确填充。你能建议我怎样才能正确地产生这个信息。
{
"applicationName":"Tesing",
"cpuCount":"12",
"hostdescName":"localhost",
"maxMemory":"0",
"maxWallTime":"0",
"minMemory":"0",
"nodeCount":"1",
"processorsPerNode":"12",
"serviceDesc":{"inputParams":"","outputParams":[]}}
[编辑] 我的代码如下所示。
$(document).ready(function(){
var inputCount = 0;
var outputCount = 0;
$("p1").live("click", function(){
inputCount++;
$(this).after("<br/>");
$(this).after("Input Name *:" +
"<input type="text" id="inputName" + inputCount + "" name="inputName" + inputCount + "" value="echo_input" size="50"><br/>");
$(this).after("Input Type *:" +
"<input type="text" id="inputType" + inputCount + "" name="inputType" + inputCount + "" value="String" size="50"><br/>");
});
$("p2").live("click", function(){
$(this).after("Output Name *:" +
"<input type="text" id="outputName" + outputCount + "" name="outputName" + outputCount + "" value="echo_output" size="50"><br/>");
$(this).after();
$(this).after("Output Type *:" +
"<input type="text" id="outputType" + outputCount + "" name="outputType" + outputCount + "" value="String" size="50"><br/>");
});
$('[name="btn2"]').click(function(){
var appName = $("#appName1").val();
var exeuctableLocation = $("#exeuctableLocation1").val();
var scratchWorkingDirectory = $("#scratchWorkingDirectory1").val();
var hostName = $("#hostName1").val();
var projAccNumber = $("#projAccNumber1").val();
var queueName = $("#queueName1").val();
var cpuCount = $("#cpuCount1").val();
var nodeCount = $("#nodeCount1").val();
var maxMemory = $("#maxMemory1").val();
var serviceName = $("#serviceName1").val();
var inputName1 = $("#inputName1").val();
var inputType1 = $("#inputType1").val();
var outputName = $("#outputName1").val();
var outputType = $("#outputType1").val();
var jsonRequest = {};
jsonRequest["applicationName"] = appName;
jsonRequest["cpuCount"] = cpuCount;
jsonRequest["hostdescName"] = hostName;
jsonRequest["maxMemory"] = maxMemory;
jsonRequest["maxWallTime"] = ""; //TODO
jsonRequest["minMemory"] = ""; //TODO
jsonRequest["nodeCount"] = nodeCount;
jsonRequest["processorsPerNode"] = ""; //TODO
var inArray = [];
for(var j=0; j<inputCount; j++) {
var input = {};
input["dataType"] = "input";
input["description"] = "empty";
input["name"] = $("#inputName" + j+1).val();
input["type"] = $("#inputType" + j+1).val();
inArray[j] = input;
}
var outArray = new Array();
for(var j=0; j<outputCount; j++) {
var output = {};
output["dataType"] = "output";
output["description"] = "empty";
output["name"] = $("#outputName" + j+1).val();
output["type"] = $("#outputType" + j+1).val();
outArray[j] = output;
}
var serviceDesc = {};
serviceDesc["inputParams"] = inArray;
serviceDesc["outputParams"] = outArray;
jsonRequest["serviceDesc"] = serviceDesc;
alert("printing inArray");
alert(inArray.toSource().toString());
alert(JSON.stringify(jsonRequest));
$.ajax({
beforeSend: function(x) {
if (x && x.overrideMimeType) {
x.overrideMimeType("application/j-son;charset=UTF-8");
}
},
type: "POST",
dataType: "json",
contentType: "application/json;charset=utf-8",
url: "http://localhost:7080/airavata-registry-rest-services/registry/api/applicationdescriptor/build/save/test",
data: jasonRequest
}).done(function(msg) {
alert("Data Saved: " + msg);
});
});
});

旁注：谁是贾森？使用JSON来避免混淆。 –
它应该这样工作。你确定inArray和outArray是合适的填充数组吗？ （还可以使用[]代替新阵列（），但是这不应该是错误） – SoonDead
@TimS。它必须是他所指的JSON Statham。 – SoonDead
