Folks, DynamoDB call returns a JSON Object, which I would like to parse, and grab the password hash field
jsonString = JSON.stringify(data)
console.log(jsonString)
output:
{"Count":1,"Items":[{"token":{"S":"token"},"uid":{"S":"33c02130-66b5-11e3-bdb0-7d9889f293b5"},"password":{"S":"$2a$10$ervzJ.DWjHOXRtJSugTaWuquI2OvPLyipa4YXecc/2KdQnmhrHxr6"},"username":{"S":"foo"},"plate":{"S":"dinner"},"name":{"S":"Test Name"},"server":{"S":"bar"}}]}
How would i parse this string, and retrieve the 'password' field?
The following code does not work:
console.log(jsonString.password)
console.log(jsonString.uid)
The following returns undefined:
console.log(data.password);
Thanks!

This is already an object, so you can do this:
var str = {"Count":1,"Items":[{"token":{"S":"token"},"uid":{"S":"33c02130-66b5-11e3-bdb0-7d9889f293b5"},"password":{"S":"$2a$10$ervzJ.DWjHOXRtJSugTaWuquI2OvPLyipa4YXecc/2KdQnmhrHxr6"},"username":{"S":"foo"},"plate":{"S":"dinner"},"name":{"S":"Test Name"},"server":{"S":"bar"}}]};
alert(str.Items[0].password.S);

This is a simple question about JavaScript,
Say I got the following string:
A)My Name B)My Name C)My Name
now I give to a function the key #1 expecting to replace the second occurrence of My Name inside that function and return:
A)My Name B) C)My Name
I haven't found the solution to this anywhere online so I'm asking.

You could use split to separate the string into the parts, then join the before and after back together:
function removeNthMatch(input, removeString, removeIndex) {
var splitString = input.split(removeString);
result = splitString.slice(0, removeIndex + 1).join(removeString)
+ splitString.slice(removeIndex + 1).join(removeString);
}
input = "A)My Name B)My Name C)My Name";
removeString = "My Name";
removeIndex = 1;
console.log(removeNthMatch(input, removeString, removeIndex));

I'm trying to get the id of an radiobutton to be added to href when the link is clicked. I tried searching google for a long time. But maybe i'm missing because it's very basic.
I do have a bit of code written but it doesn't work. Help?
function ProductIDLink() {
var url = "/bbbb/aaaaaaa/" + ('.aaasaff:radio:checked').attr('id');
$("#safad").attr("href", url)
}

Looks like you've just forgotten a $:
... ('.aaasaff:radio:checked').attr('id')
should be
... $('.aaasaff:radio:checked').attr('id')

From what I can see the $ was missing.
function ProductIDLink() {
var url = "/bbbb/aaaaaaa/" + $('.aaasaff:radio:checked').attr('id');
$("#safad").attr("href", url)
}

I am trying to concatenate a variable into a constructor in JavaScript
I have a variable like this:
var selectedLayer = "myLayer";
and then I am creating a Leaflet tile layer, I want to then incorporate the variable into the constructor:
test = new L.TileLayer.WMS('http://localhost/geoserver/wms',{layers : 'geonode:<selectedLayer>', format: 'image/png'});

string concatenation in javascript is done with the simple +, so your case would be:
{
layers: 'geonode:' + selectedLayer,
format: 'image/png'
}
