Passing parameters into a url - javascript

I need to pass some parameters into a URL
For example, my URL is mypage/generator/
So my generator consists of a generator(code, id, text)
Is the following a correct way of doing it
Check:function () {
var generator = code + "," + id + ", " + text;
Window.location.href = "mypage/" + generator + "/"
}

You can try this:
function check(){
var generator=code +","+ id +","+ text;
window.location.href="mypage?data="+generator+"";
}
and you can access the data from request.getparameter("data");
This might help you!

Can't send parameter containing "#" to dot net web service from ajax

Cant send parameter containing "#" to dot net web service from ajax.
var s = encodeURI(
"http://subdomain.mydomain.domain.asmx/getData?OUserId=" + UserId +
"&Token=" + Token +
"&OrgId=" + OrgId +
'&Message=' + Message +
'&Schoolid=' + SchoolId +
'&SessionId=" ' + SessionId +
'&UnicodeValue=' + UnicodeValue +
'&ClassID=' + ClassIdCommaSeparated.toString()
);
$.ajax({
url: s,
error: function(err) {
alert(err);
},
success: function(data) {....
}
});
Here classIdCommaSeparated is 1#1#1#1#1,1#1#1#1#1,1#1#1#1#1.
Use encodeURIComponent on the individual parts, rather than encodeURI on the whole:
var s = "http://subdomain.mydomain.domain.asmx/getData?OUserId=" + encodeURIComponent(UserId) +
"&Token=" + encodeURIComponent(Token) +
"&OrgId=" + encodeURIComponent(OrgId) +
'&Message=' + encodeURIComponent(Message) +
'&Schoolid=' + encodeURIComponent(SchoolId) +
'&SessionId=" ' + encodeURIComponent(SessionId) +
'&UnicodeValue=' + encodeURIComponent(UnicodeValue) +
'&ClassID=' + encodeURIComponent(ClassIdCommaSeparated.toString());
$.ajax({
url: s,
error: function(err) {
alert(err);
},
success: function(data) {....
}
});
Technically, both the name (before the =) and the value (after the =) need to be encoded, but when your names consist just of the letters A-Z (in upper or lower case) or digits, like yours do, encoding them doesn't change them at all. (If you didn't know what those names were, you'd definitely want to pass them through encodeURIComponent.)
several hours after i am not able to understand what is arising this problem.but i have worked around to have a temporary solution to the problem.i have used underscore in place of # and i got it working.thanks #T.J. Crowder for having a look upon.

jQuery get an Array from json file

I need to get an array from a json file and I have no idea how to do it.
Here's the code I want to get the array from:
$.getJSON('saveGames/userID' + userID + '_SAVEALPHA.json', function(data) {
console.log("Save data from: userID" + userID + "_SAVEALPHA.json: " + data);
var testVar = jQuery.parseJSON(data);
var pokemonAryTest = testVar[0].pokemon;
pokemonAry = [pokemonAryTest];
console.log("loaded players Pokemon: " + pokemonAry);
console.log(pokemonAry[0])
});
I have tried to change the index of pokemonAry to 1 and it returns undefined. And when I keep the index the same, it returns ["Pikachu, Charmander"] so I think its acting like as if it's a string.
Here's the .json:
"[{\"userID\":\"1\",\"saveName\":\"g\",\"pokemon\":[\"Pikachu, Charmander\"]}]"
When you are using getJSON() method no need to parse JSON data, jQuery take care of it. :)
$.getJSON('saveGames/userID' + userID + '_SAVEALPHA.json', function(data) {
console.log("Save data from: userID" + userID + "_SAVEALPHA.json: " + data);
var pokemonAry = data[0].pokemon;
console.log("loaded players Pokemon: " + pokemonAry);
console.log(pokemonAry[0])
});

pass two parameters DDL in JavaScript / jQuery

This function works fine but passes only one parameter from one DropDownList to the controller. How to make the transfer of two parameters of an (two DDL)?
$(function () {
$('#DDL_1_ID').change(function () {
var URL = $('#FormID').data('someAction');
$.getJSON(URL + '/' + $('#DDL_1_ID').val(), function (data) {
$.each(data, function (i, format) { });
});
});
});
You could continue appending query string parameters as you've done with ddl_1_tc...
$.getJSON(URL + '/' + $('#DDL_1_ID').val() + '&myotherparam=' + yourotherinput
Your url appears to be malformed though. I believe you're missing the name of the first value...
$.getJSON(URL + '?nameforfirstparam=' + $('#DDL_1_ID').val() + '&nameforsecondparam=' + yoursecondinput

Trying to add variables to twitter json url

I'm trying to create a function which uses a combination of jquery, json and javascript to retrieve a twitter feed using the $.getJSON() method.
I have the function working with a static url like so:
$.getJSON("http://twitter.com/status/user_timeline/owzzz.json?count=1&callback=?", function(data) {
What I'm trying to do is replace where you see the username owzzz and count with values passed into the function.
the function looks something like this:
var twitterFeed = function(username, count){
$.getJSON("http://twitter.com/status/user_timeline/owzzz.json?count=1&callback=?", function(data) {
$.each(data, function(i) {
var timestamp = new Date(this.created_at);
var text = this.text;
$("#twitter").html(text +'<a href="http://twitter.com/' + username + '/" class="timestamp">' + username + ' <span>' + timestamp.toDateString() + '<\/span><\/div>' ).click(function(e) {
window.location = 'http://twitter.com/' + username;
e.preventDefault();
});
});
}); } twitterFeed('owzzz',1);
I can add the passed value username in the .html() but not inside the getJSON();
Any idea how I would go about this?
Do the same as you do in the html function: String concatenation.
$.getJSON("http://twitter.com/status/user_timeline/" + username + ".json?count=" + count + "&callback=?", ...)
string concatenation.
$.getJSON(
'http://twitter.com/status/user_timeline/' + username + '.json' +
'?count=' + count + '&callback=?'
);

jQuery/Javascript - reload current page with an appended querystring?

I've got a dropdown menu on my form, which when something is selected I need to reload the current page, but with an appended querystring.
How would I go about doing this?
This is an old question but it came up first in google search results.
The solution I went with is similar to jAndy's.
window.location.pathname gives me the page's url without the query string.
I'm then able to build the query string with "?"+$.param({'foo':'bar','base':'ball'}) which I then append to the pathname and set to window.location.href.
window.location.href = window.location.pathname+"?"+$.param({'foo':'bar','base':'ball'})
var params = [
"foo=bar",
"base=ball"
];
window.location.href =
"http://" +
window.location.host +
window.location.pathname +
'?' + params.join('&');
That code within your change event handler will do the trick.
For instance:
$('#my_dropdown_id').bind('change', function(){
var params = [
"foo=bar",
"base=" + $(this).val()
];
window.location.href = "http://" + window.location.host + window.location.pathname + '?' + params.join('&');
});
If you go with the top rated answer, you may want to replace
http://
in the code with
window.location.protocol
so that it works for other protocols, like https or file. So
window.location.href = window.location.protocol + "//" + window.location.host + window.location.pathname + '?' + params.join('&');
Actually, there a built-in function of location that you can use, the name of the function is assign.
For appending or modifying there is another built-in function of the URL class that you can use too. the name of the function is searchParams.
So for your case you just need below example:
const url = new URL(location.href);
url.searchParams.set('key', 'value');
location.assign(url.search);
Update 2022
I create a TypeScript function to apply redirect with params more easier:
const isClient = (): boolean => typeof window !== 'undefined';
type ParamsType = { [key: string]: string | number };
const redirectUrl = (url: string, params?: ParamsType): void => {
if (isClient()) {
try {
const _url = new URL(url);
if (params) {
const keyList = Object.keys(params);
for (let i = 0; i < keyList.length; i += 1) {
const key = keyList[i];
_url.searchParams.set(keyList[i], params[key]?.toString());
}
}
window.location.assign(_url.href);
} catch (e) {
throw new Error('The URL is not valid');
}
}
};
export default redirectUrl;
If you want a simple way to preserve the query string and possibly append to it, use window.location.search; here's a snippet:
var search = window.location.search + (window.location.search ? "&" : "?");
search += "param1=foo&param2=bar";
window.location.href = window.location.protocol + "//" + window.location.host + window.location.pathname + search;
You can, of course, use a more sophisticated way of building the rest of your query string, as found in the other examples, but the key is to leverage Location.search.
If you have an existing querystring that you'd like to keep then this version does that and adds your new params to any existing ones. The keys are converted to lowercase so that duplicates are not added. Maintaining the quersytring does make the solution more complicated, so I'd only do this if you need to.
$("#sortby").change(function () {
var queryString = getQueryStrings();
// Add new params to the querystring dictionary
queryString["sortby"] = $("#sortby").val();
window.location.href =
window.location.protocol + "//" +
window.location.host +
window.location.pathname +
createQueryString(queryString);
});
// http://stackoverflow.com/questions/2907482
// Gets Querystring from window.location and converts all keys to lowercase
function getQueryStrings() {
var assoc = {};
var decode = function (s) { return decodeURIComponent(s.replace(/\+/g, " ")); };
var queryString = location.search.substring(1);
var keyValues = queryString.split('&');
for (var i in keyValues) {
var key = keyValues[i].split('=');
if (key.length > 1) {
assoc[decode(key[0]).toLowerCase()] = decode(key[1]);
}
}
return assoc;
}
function createQueryString(queryDict) {
var queryStringBits = [];
for (var key in queryDict) {
if (queryDict.hasOwnProperty(key)) {
queryStringBits.push(key + "=" + queryDict[key]);
}
}
return queryStringBits.length > 0
? "?" + queryStringBits.join("&")
: "";
}
I was having a requirement to open a particular tab after reloading. So I just needed to append the #tabs-4 to the current url. I know its irrelevant to current post but it could help others who come to this just like I did.
Using the code
window.location = window.location.pathname
+ window.location.search + '#tabs-4';
did'nt work for me but below code did.
location = "#tabs-4";
location.reload(true);
