I have a grid using jqgrid. I need to store the some data returned by the url:, in a local variable so that I can display it in the subgrid. For this I add that column as a hidden column in the main grid, which is of the format in json:
"Details":[{"Name":"ttt", "Quantity":"12"}] .
Then in the loadcomplete: function I save the value to a variable using
var griddata = $("#grid').getCol('Details', false);
Now when I access griddata[0], I get a object Object. I tried to parse it to get the values correctly, but to no avail. I tried:
griddata[0].Details.Name
or
griddata[0].Details.0.Name
or
griddata[0].Name,
but all failed. I guess I am missing the format if the data returned by the getcol() function.I looked up the documentation on the method and it says that it returns just the values when we specify false, but could not get any examples.
If there are any examples or if there are any pointer to the solution, it will be greatly appreciated.
If you check the type of griddata[0] (for example with typeof operator) you will see that it has type of string - this is because the value you are getting is the result of toString() on the object you have passed. The reason for that is the way in which jqGrid is treating values.
If you want to store JSON as the value, you need to stringify it entirely:
"Details": "[{\"Name\":\"ttt\", \"Quantity\":\"12\"}]"
Now you can deserialize those string values into objects like this:
var griddata = $.map($("#grid").jqGrid('getCol', 'Details', false), function(value) {
return JSON.parse(value);
});
After that you can access the objects in the way you want:
var name = griddata[0].Name;
var quantity = griddata[0].Quantity;
As an alternative you can split your object into two columns, so the values can be accessed directly with getCol.

Basically I have a complex object that retrieves the GPT API (google publisher tag) with this function:
googletag.pubads().getSlots();
The object value is something like this:
I need to know if there is a way to compare the value of each property with an X value without getting a problem of recursivity (because the object is huge and i need to to that validation several times)
Also, I tried to convert that object into a JSON with JSON.stringify(), and then tried to get the value with a regex, faster, but with this option, I have the problem with Cyclic Object Value.
Any suggestions ?
it's more simple. try it to convert it into an array and later use a filter for comparative with your value.
var objGoogle = {};
var arrayObjectGoogle = [objGoogle];
var filter = arrayObjectGoogle.filter(function(obj){
obj.yourAttr == yourValue; });
this will give you a second array with the values found it. later, index the array for pick up the value do you need.
I am creating a restructured json model in our sapui5 app wherein the data is being received from the odata response. I am using the json.setproperty() method.
if i try n access the value with following methods
var two = 2;
var test = "Count"
var three = test+two
alert(odata.results[0][three]);
correct value is being alerted with object notation as against Nan being alerted if dot notation was used.
so in a loop im trying to fill the content of the json
for(var i=0;i<=count-2;i++){
var z = "Count"+i;
countjson.setProperty("/data/data/"+i+"/Count",odata.results[0].z);
countjson.setProperty("/data/data/"+i+"/Count",odata.results[0][z]);
}
Nan is being returned when im trying with the dot notation and undefined is being returned with object notation.
if i hardcode the path i.e odata.results[0].Count4 i am getting the 4th element from the odata resp and getting set in all fields of the new json.
Please help me with the above.
Best regards

You cannot access a multidimensional array like that. Instead try using this -
odata.results[0][odata.results[0].indexOf(three)]
I have a JSON collection produced from an object graph. Shown below is an example value. I am having trouble accessing the nested 'Type' object to retrieve any of it's values.
[{"Id":1,"Name":"My Name","Type":{"Id":1,"Name":"my Value"}}]
I am using a JS component that has a property that can be assigned a value similar to below.
myProperty: Type.Name, //Not working
Can someone recommend how I set this value?
What you have is a JavaScript array, not an object, and certainly not JSON. So if you have
var arr = [{"Id":1,"Name":"My Name","Type":{"Id":1,"Name":"my Value"}}]
you'd need to index it, and grab the Type object off of that.
var typeName = arr[0].Type.Name;
I had a question about best practice for passing a list of XML xpath values to a function.
I'm just a beginner programmer and am just learning javascript.
What I want to do is define an object with criteria (done this okay), and a list of results I want back from a query, both of which that can be passed to a function.
The following is working, but I'm thinking that probably sending the xpath as the key in the object is probably not the best idea, with null values. I get back an object from the function with the keys I sent and the values.
var myCriteria = { prospect_id : 98888158, type : 13};
var myResults = { 'total_results':null , 'visitor_activity/id':null };
myResults = pardotQuery(authentication, 'visitorActivity', myCriteria, myResults);
I thought about just passing it in as an array, then converting it into an object that gets returned with keys, and values.
Please advice what would be best.
Thanks.
Hi I am using a Java script variable
var parameter = $(this).find('#[id$=hfUrl]').val();
This value return to parameter now
"{'objType':'100','objID':'226','prevVoting':'" // THIS VALUE RETURN BY
$(this).find('[$id=hfurl]').val();
I want to store objType value in new:
var OBJECTTYPE = //WHAT SHOULD I WRITE so OBJECTTYPE contain 400
I am trying
OBJECTTYPE = parameter.objType; // but it's not working...
What should I do?
Try using parameter['objType'].
Just a note: your code snippet doesn't look right, but I guess you just posted it wrong.
Ok, not sure if I am correct but lets see:
You say you are storing {'objType':'100','objID':'226','prevVoting':' as string in a hidden field. The string is not a correct JSON string. It should look like this:
{"objType":100,"objID":226,"prevVoting":""}
You have to use double-quotes for strings inside a JSON object. For more information, see http://json.org/
Now, I think with $(this).find('[$id=hfurl]'); you want to retrieve that value. It looks like you are trying to find an element with ID hfurl,but $id is not a valid HTML attribute. This seems like very wrong jQuery to me. Try this instead:
var parameter = $('#hfurl').val();
parameter will contain a JSON string, so you have to parse it before you can access the values:
parameter = $.parseJSON(parameter);
Then you should be able to access the data with parameter.objType.
Update:
I would not store "broken" JSON in the field. Store the string similar to the one I shoed above and if you want to add values you can do it after parsing like so:
parameter.vote = vote;
parameter.myvote = vote;
It is less error prone.
