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);

Suppose the JavaScript variable is:
var sourceString="stack {overflow} is the best {place} to clear {technical} doubts";
Output javascript string array should contain: overflow,place,technical
or {overflow},{place},{technical}
I am fine with both the results.
You could use regex to accomplish this:
sourceString.match(/{.*?}/g)
var getMatchingGroups = function(s) {
var r=/\{(.*?)\}/g, a=[], m;
while (m = r.exec(s)) {
a.push(m[1]);
}
return a;
};
getMatchingGroups(sourceString) // ["overflow", "place", "technical"]

I have a simple "en.txt"
"TITLE" => "Amazing title of my page"
"COPYRIGHT" => "Copyright my site"
"BLABLA" => "A amazing sentence"
And I would like convert this in array for nodeJS with FS.
Thanks for your help.
First, read the file data using the fs.readFile method. Once you have the file data in a variable, you can convert it into an array using the following regular expression:
var regex = /"([^"]+)"\s*=>\s*"([^"]+)/g;
var match, results = {};
while((match = regex.exec(fileData)) !== null){
results[match[1]] = match[2];
}
console.log(results); // contains js array of data
See Fiddle.

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'
}

I'm looking for a regex to test if a url is a root url:
http://site.org TRUE
http://www.example.com TRUE
...
http://www.example.com/dir FALSE
http://www.example.com/image.jpg FALSE
http://www.example.com/dir/file.doc FALSE
Try below regex will do the work
/^https?\:\/\/[^\/]+\/?$/
I tested like this:
var URL = "http://jsfiddle.net/";
var check =/^https?\:\/\/[^\/]+\/?$/.test(URL);
alert(check);
JSFiddle
try this:
var str='url...';
if(str.indexOf("/")<str.indexOf(".")&&(str.indexOf("http://")>-1))
return true;
else
return fals;
Try out with this regular expression
(?\w+)://(?[\w#][\w.:#]+)/?[\w.?=%&=-#/$,]*
