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.

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"]

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);

I have a ajax response array and I want get the value of there index.
[{"UserLatitude":"33.7543","UserLongitude":"-84.3744"}{"UserLatitude":"22.6962","UserLongitude":"75.8651"},{"UserLatitude":"22.6963","UserLongitude":"75.8654"},{"UserLatitude":"37.7858","UserLongitude":"-122.406"},{"UserLatitude":"0","UserLongitude":"0"},{"UserLatitude":"37.7858","UserLongitude":"-122.406"},{"UserLatitude":"37.7858","UserLongitude":"-122.406"},{"UserLatitude":"37.7858","UserLongitude":"-122.406"},{"UserLatitude":"0","UserLongitude":"0"},{"UserLatitude":"0","UserLongitude":"0"},{"UserLatitude":"22.6962","UserLongitude":"75.8653"},{"UserLatitude":"22.6963","UserLongitude":"75.8654"},{"UserLatitude":"0","UserLongitude":"0"},{"UserLatitude":"33.7543","UserLongitude":"-84.3745"},{"UserLatitude":"0","UserLongitude":"0"},{"UserLatitude":"0","UserLongitude":"0"},{"UserLatitude":"33.7543","UserLongitude":"-84.3744"}]
You're missing a comma after the first array object which is causing an error. Otherwise result[0].UserLatitude will work - jsfiddle.
You need to iterate the array and then check those values are matching like
$.each (arr, function (index, value) {
if(value["UserLatitude"] == "33.7543" && value["UserLongitude"] == "-84.3744") {
console.log(index);
return false;
}
});
if matches found, print the index and exit the loop.

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 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'
}
