I have a json like this:
var x = {"foo:bar":"xyz"};
I can get xyz by call x["foo:bar"] but is there anyway to get xzy by calling just bar and remove the foo prefix? something like x["bar"]? The json is converted from xml with namespace like that, I can't change it. Thanks
You can iterate over the property names and remove the prefix:
function removePrefix(x){
var temp = {};
for(var key in x){
temp[key.substr(key.indexOf(':')+1)] = x[key];
}
return temp;
}
var x = {"foo:bar":"xyz"};
x = removePrefix(x);
console.log( x['bar'] ); // xzy
console.log( x.bar ); // xyz
You would create a JSON string which would look like this:
var x = {"foo":"xyz"};
your current key: "foo:bar" does not have any special meaning in JSON, it's part of the key.

So I want to get the Object which is essentialy a string. The issue is I cant transfer it into the string format since the resulting string is just anything but the thing I want. Bringing the object into a json doesnt bring a proper string either so my only way of achieving that is the concat method.
I have a Popup-Love which returns the string as follows foo, foo1 ,foo2 while I need it as
'foo1','foo2',...,'foo999' .
My method manages to do that for the first element while all the other elements remove the apostrophe resulting in something like 'foo,foo1,foo2'. How do i fix that?
var i = 0;
if(i == 0){
var t ="'";
var t = t.concat(apex.item("P29_STANDORT").getValue());
var t = t.concat("'");
apex.item("P29_TEST").setValue(t);
i = i +1;
} else {
var t = t.concat("'");
var t = t.concat(apex.item("P29_STANDORT").getValue());
var t = t.concat("'");
apex.item("P29_TEST").setValue(t);
}
You can "overwrite" the native toString() function of the Object and replace it with a function that does what you want. Something like below
function MyObj(){
this.creationTime = new Date().toLocaleString();
}
MyObj.prototype.toString = function something(){
return 'I was created on ' + this.creationTime;
}
var myObj = new MyObj();
console.log('String version of my custom object: ' + myObj);
I have a job to refractor strings to start using json so they can just pass json objects. So I have made array of names and then I'm trying to go through and make key and values but I'm getting an error in the console that it cant find x of no value. Can someone point me in the right direction?
var newName = ['ManagingOrg', 'ActiveOrg', 'Severity', 'SeverityClassification', 'WorkQueue', 'TicketState',................ to long to post];
$().each(newName, function (key, value) {
key = newName[this];
value = newValues[this] = $('#' + key).val();
newArray = [key][value];
newArray = JSON.stringify(newArray);
alert(newArray);
$('.results').html(origArray[TicketNumber]);
});
I'm assuming you have "newValues" and "origArray" defined elsewhere?
In any case you'll need to at least adjust the following:
"$().each" should be $.each
"newArray" should be defined outside and you should use newArray[key] = value
you don't have a variable "TicketNumber" defined and so you should wrap "TicketNumber" in quotes
this is a reserved word so you shouldn't use it in "newName[this]" or "newValues[this]"
I suggest using a for loop instead of $.each() based on what you're trying to do inside.
https://msdn.microsoft.com/en-us/library/bb299886.aspx
var origArray = [];
var newName = ['ManagingOrg', 'ActiveOrg', 'Severity', 'SeverityClassification'
];
for (var i = 0; i < newName.length - 1; i++) {
var object = {};
object[newName[i]] = newName[i];
object = JSON.stringify(object);
origArray.push(object);
}
I've read some question but I still can't figure out how to do it
I have a url example.com/event/14aD9Uxp?p=10
Here I want to get the 14aD9Uxp and the value of p
I've tried using split('/'+'?p=') but it doesn't work
I want to use regex but I dont really understand how to use it
var URL='example.com/event/14aD9Uxp?p=10';
var arr=URL.split('/');//arr[0]='example.com'
//arr[1]='event'
//arr[2]='14aD9Uxp?p=10'
var parameter=arr[arr.length-1].split('?');//parameter[0]='14aD9Uxp'
//parameter[1]='p=10'
var p_value=parameter[1].split('=')[1];//p_value='10';
I've created a generalized function (restricted in some ways) that will return the GET value given the parameter. However this function will only work correctly provided that you do not Rewrite the URL or modify the URL GET SYNTAX.
//Suppose this is your URL "example.com/event/14aD9Uxp?p=10";
function GET(variable) {
var str = window.location.href;
str = str.split("/");
// str = [example.com, event, 14aD9Uxp?p=10]
//Get last item from array because this is usually where the GET parameter is located, then split with "?"
str = str[str.length - 1].split("?");
// str[str.length - 1] = "14aD9Uxp?p=10"
// str[str.length - 1].split("?") = [14aD9Uxp, p=10]
// If there is more than 1 GET parameter, they usually connected with Ampersand symbol (&). Assuming there is more, we need to split this into another array
str = str[1].split("&");
// Suppose this is your URL: example.com/event/14aD9Uxp?p=10&q=112&r=119
// str = [p=10, q=112, r=119]
// If there is only 1 GET parameter, this split() function will not "split" anything
//Remember, there might only be 1 GET Parameter, so lets check length of the array to be sure.
if (str.length > 1) {
// This is the case where there is more than 1 parameter, so we loop over the array and filter out the variable requested
for (var i = 0; i < str.length; i++) {
// For each "p=10" etc. split the equal sign
var param_full_str = str[i].split("=");
// param_full_str = [p, 10]
//Check if the first item in the array (your GET parameter) is equal to the parameter requested
if (param_full_str[0] == variable) {
// If it is equal, return the second item in the array, your GET parameter VALUE
return param_full_str[1];
}
}
} else {
// This is the case where there is ONLY 1 GET parameter. First convert it to a String Type because Javascript decided that str was no longer a String
// Now split it with the equal sign.
str = str.toString().split("=");
return str[1];
}
}
document.write(GET("p"));
function $_GET(param) {
var vars = {};
window.location.href.replace(
/[?&]+([^=&]+)=?([^&]*)?/gi, // regexp
function( m, key, value ) { // callback
vars[key] = value !== undefined ? value : '';
}
);
if ( param ) {
return vars[param] ? vars[param] : null;
}
return vars;
}
I have collected this from here:
http://www.creativejuiz.fr/blog/javascript/recuperer-parametres-get-url-javascript
It works great.
To use it just grab your parameter like:
var id = $_GET('id');
const url = new URL('http://example.com/event/14aD9Uxp?p=10');
const [,, eventId ] = url.pathname.split('/');
const p = url.searchParams.get('p');
Browser support:

https://caniuse.com/#feat=urlsearchparams
Simple no-regex way
var s = "example.com/event/14aD9Uxp?p=10";
var splitByForwardSlash = s.split('/');
// To get 14aD9Uxp
splitByForwardSlash[splitByForwardSlash.length-1]
// To get p=10
splitByForwardSlash[splitByForwardSlash.length-1].split('?')[1]
I think you know how to go from here :-)
Get query string
var queryString = window.location.search;
removes ? from beginning of query string
queryString = queryString.substring(1);
query string processor
var parseQueryString = function( queryString ) {
var params = {}, queries, temp, i, l;
// Split into key/value pairs
queries = queryString.split("&");
// Convert the array of strings into an object
for ( i = 0, l = queries.length; i < l; i++ ) {
temp = queries[i].split('=');
params[temp[0]] = temp[1];
}
return params;
};
// query string object
var pageParams = parseQueryString(queryString);
// CSS variables
var target = pageParams.target;
var prop = pageParams.prop;
var value = pageParams.value;
// can't get to work -->
jQuery(target).css({
prop : value,
});
I want to be able to supply a query like this one "?target=body&prop=display&value=none" and make the whole body disappear or target certain elements by their class.
You wouldn't be able to use prop as a key-variable for the object you're passing to .css(). In this case, it would translate to a literal string 'prop'. Instead, you'd have to do something like:
jQuery(target).css(prop,value);
Note: be careful about that trailing comma in that hash (after value). Some browsers will error at that point.
In order to create a css object which you can pass to jQuery, I suggest something like this:
// Create css obj
var cssObj = {};
cssObj[prop] = value;
After this, the code works fine to me. See the full solution here:
http://jsfiddle.net/q97DH/4/
I recommend removing the question mark with a regex - see comment below.
This is the code:
var groups = {
"JSON":{
"ARRAY":[
{"id":"fq432v45","name":"Don't use me."},
{"id":"qb45657s","name":"Use me."}
]
}
}
I want to get the name value where the id is "qb45657s" how could this be accomplished? I figured the obvious loop through all of the array and check if it's equal but is there an easier way?
Edit: I cannot change "Array" to an object because I need to know the length of it for a different function.
You can simply filter on the given id:
groups["JSON"]["ARRAY"].filter(function(v){ return v["id"] == "qb45657s"; });
This will return [{"id":"qb45657s","name":"Use me."}]
Assuming you had a valid JSON string like this (note I say valid, because you need an enclosing {} or [] to make it valid):
var json = '{"JSON":{
"ARRAY":[
{"id":"fq432v45","name":"Don't use me."},
{"id":"qb45657s","name":"Use me."}
]
}
}';
You would just parse it into an actual object like this:
var jsonObj = JSON.parse(json); // makes string in actual object you can work with
var jsonArray = jsonObj.JSON.ARRAY; // gets array you are interested in
And then search for it like:
var needle = 'qb45657s';
var needleName;
for (var i = 0; i < jsonArray.length; i++) {
if (jsonArray[i].id === needle) {
needleName = jsonArray[i].name;
}
}
