create JSONArray ([{},{},{}]) in JS
var data = [];
data.push({
"id" : 1,"val" : $('#projectName').val()
});
data.push({
"id" : 2,"val" : $('#description').val()
});
data.push({
"id" : 3,"val" : $('#startdate').val()
});
data.push({
"id" : 4,"val" : STATUS_NOT_START
});
var id = 5;
while($("#" + id).length > 0){
data.push({
"id" : id,"val" : $("#" + id).val()
});
id++;
}
ajax pass JSONArray String to Controller:
$.ajax({
type : "Post",url : "createProject.html",data : "jsonArray=" + JSON.stringify(data) + "&depId=" + depId + "&groId=" + groId + "&objId=" + objId,success : function(response){
var alertText = "Project " + $('#projectName').val() + " is successfully created! Project ID: " + response;
addAlert("alert-success",alertText,"#alertdiv");
},error : function(e){
var alertText = 'Error: ' + e;
addAlert("alert-error","#alertdiv");
}
});
Controller将JSONArray String转换成JSONArray
import net.sf.json.JSONArray; JSONException; JSONObject; JSONSerializer; public class TestJson { static void parseProfilesJson(String the_json){ try { JSONArray nameArray =(JSONArray) JSONSerializer.toJSON(the_json); System.out.println(nameArray.size()); for(Object js : nameArray){ JSONObject json = (JSONObject)js; System.out.println(json.get("date")); } } catch (JSONException e) { e.printStackTrace(); } } void main(String[] args) { String s = "[{\"date\":\"2012-04-23\",\"activity\":\"gym\"},{\"date\":\"2012-04-24\",\"activity\":\"walking\"}]"; parseProfilesJson(s); } }
