I can't figure out how to correctly use push state. I'm getting weird url's like so:
http://website.net/home?http://website.net/home=undefined&tab=browse
And can't seem to get it to work no matter what I try. I need domain/path to stay the same, I just want to rebuild the querystring (which I do in another function) then apply history.pushState()
Here's a basic look at the code, abbreviated to show the problem in question.
var sk = {
//push function
pushState: function(qs,callback){
var i = 0, uri = '';
$.each(qs,function(k,v){
if(k=="" || v==""){
delete qs[k];
}
});
$.each(qs,function(k,v){
if(i == 0){
uri +='?';
}else{
uri +='&';
}
uri +=k+'='+encodeURIComponent(v);
i++;
});
var obj ={ Title: $('title').html(), Url: uri }
if(typeof callback !== "undefined" && callback !== false){
obj[callback[0]] = callback[1];
}
history.pushState(obj,obj.Title,obj.Url);
},
//parse current url and return querystring
getQSvars : function(){
var vars = {}, hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars[hash[0]] = hash[1];
}
return vars;
},
};

** angular newbie alert **
I have a web page that is called with several querystring values.
I would like to populate a couple of data binding areas with values coming in from the querystring.
<span class="username">{{firstName}}{{lastName}}</span>
and i am parsing the querystring using this
var vars = [], hash;
var q = document.URL.split('?')[1];
if (q != undefined) {
q = q.split('&');
for (var i = 0; i < q.length; i++) {
hash = q[i].split('=');
vars.push(hash[1]);
vars[hash[0]] = hash[1];
}
}
alert(vars['lastName']);
I am not sure how to actually drive the values into the data binding fields.
Use $location provider from angular.
You can do var searchObject = $location.search();
Then get key of this object. Like searchObject.lastName
angular.controller("ctrl",['$location',function($location){
/**Ctrl code **/
}]);
I had to go with several portions from several tuts along with a hammer to get something into place.
That being said, placement of the code is particularly important.
a majority of the code has to be done at the beginning of the page, and in the head section.
the suggestion for the $location was a good one, but it seemed to fail each time i placed it into the code block.
Here is the primary code block...
<script>
var dashboardApp = angular.module('dashboardApp', []);
dashboardApp.controller('userNameCtrl', function ($scope) {
var vars = [], hash;
var q = document.URL.split('?')[1];
if (q != undefined) {
q = q.split('&');
for (var i = 0; i < q.length; i++) {
hash = q[i].split('=');
vars.push(hash[1]);
vars[hash[0]] = hash[1];
}
}
$scope.firstName = vars['firstName'];
$scope.lastName = vars['lastName'];
});
<body ng-app="dashboardApp">
<span class="username" ng-controller="userNameCtrl">{{firstName}} {{lastName}}</span>
This code block fails with no error messages, but it crashes way out, and blows out the remaining javascript block
var dashboardApp = angular.module('dashboardApp', []);
dashboardApp.controller('userNameCtrl', function ($scope, $location) {
alert("First Name is - " + $location.search()['firstName']);
var vars = [], hash;
var q = document.URL.split('?')[1];
if (q != undefined) {
q = q.split('&');
for (var i = 0; i < q.length; i++) {
hash = q[i].split('=');
vars.push(hash[1]);
vars[hash[0]] = hash[1];
}
}
$scope.firstName = vars['firstName'];
$scope.lastName = vars['lastName'];
});
my url look like http://localhost:13562/Student/RefreshStudents?sort=FirstName&sortdir=ASC&page=1
now i am looking for a function where i will pass url and query string name then that should return value.
so i did it this way but not working.
function getQueryVariable(url,variable) {
var query = url;
var vars = query.split('&');
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split('=');
if (decodeURIComponent(pair[0]) == variable) {
return decodeURIComponent(pair[1]);
}
}
console.log('Query variable %s not found', variable);
}
calling like this way
var x='http://localhost:13562/Student/RefreshStudents?sort=FirstName&sortdir=ASC&page=1'
alert(getQueryVariable(x,'sort'));
alert(getQueryVariable(x,'sortdir'));
alert(getQueryVariable(x,'page'));
where i made the mistake?
EDIT
working code
$.urlParam = function(url,name){
var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(url);
if (results==null){
return null;
}
else{
return results[1] || 0;
}
}
var x='http://localhost:13562/Student/RefreshStudents?sort=FirstName&sortdir=ASC&page=1'
alert($.urlParam(x,'sort'));
alert($.urlParam(x,'sortdir'));
alert($.urlParam(x,'page'));
https://jsfiddle.net/z99L3985/1/
thanks
may be the following will help
function getUrlVars(url) {
var vars = {};
var parts = url.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
vars[key] = value;
});
return vars;
}
var x='http://localhost:13562/Student/RefreshStudents?sort=FirstName&sortdir=ASC&page=1';
var queryVars = getUrlVars(x);
alert(queryVars['sort']);
alert(queryVars['sortdir']);
alert(queryVars['page']);
I just get this from somewhere else as well..
function getQueryVariable(variable)
{
var query = window.location.search.substring(1);
var vars = query.split("&");
console.log(vars);
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split("=");
if(pair[0] === variable){return pair[1];}
}
return(false);
}
so far its doing its job.
with url: "http://urlhere.com/general_journal?from=01%2F14%2F2016&to=01%2F14%2F2016&per_page=25&page=2"
if im going to get the 'page' variable result would be : `2`
console.log(getQueryVariable('page'));
my query variable is only getting the search.substring(1) part of the the url so basically it only gets from=01%2F14%2F2016&to=01%2F14%2F2016&per_page=25&page=2 part of the url then from that it splits it and then return the value of the string parameter you specified on the function call getQueryVariable('page') for example.
Maybe this helps
var getUrlVars = function(url){
var vars = [], hash;
var hashes = url.slice(url.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++){
hash = hashes[i].split('=');
vars.push(decodeURIComponent(hash[0]));
vars[decodeURIComponent(hash[0])] = decodeURIComponent(hash[1]);
}
if(vars[0] == url){
vars =[];
}
return vars;
}
Then in your code
var params = getUrlVars("http://localhost:13562/Student/RefreshStudents?sort=FirstName&sortdir=ASC&page=1");
console.log(params["sort"]) // FirstName
I have a link like this:
http://localhost:8162/UI/Link2.aspx?txt_temp=123abc
I want to get the value 123abc . I have followed this How can I get query string values in JavaScript? and
jquery get querystring from URL
$(document).ready(function () {
function getUrlVars() {
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
onload = function () {
alert(getParameterByName('txt_temp'));
alert(getUrlVars()["txt_temp"]);
}
});
But it does not work.
Suppose you have URL with many params eg:-
"http://localhost:8162/UI/Link2.aspx?txt_temp=123abc&a=1&b=2"
Then in js you can do like:
var url = "http://localhost:8162/UI/Link2.aspx?txt_temp=123abc&a=1&b=2"
OR
var url = window.location.href
then split main url like:
hashes = url.split("?")[1]
//hashes holds this output "txt_temp=123abc&a=1&b=2"
Then again you can split by & to get individual param
EDIT
Check this example:
function getUrlVars() {
var url = "http://localhost:8162/UI/Link2.aspx?txt_temp=123abc&a=1&b=2";
var vars = {};
var hashes = url.split("?")[1];
var hash = hashes.split('&');
for (var i = 0; i < hash.length; i++) {
params=hash[i].split("=");
vars[params[0]] = params[1];
}
return vars;
}
Output
getUrlVars()
Object {txt_temp: "123abc", a: "1", b: "2"}
It doesn't work because you're running the functions inside of onload, which doesn't fire inside of document.ready, because by the time the code inside of document.ready executes, onload has already fired. Just get your code out of the onload event:
http://jsfiddle.net/whp9hnsk/1/
$(document).ready(function() {
// Remove this, this is only for testing.
history.pushState(null, null, '/UI/Link2.aspx?txt_temp=123abc');
function getUrlVars() {
var vars = [],
hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
// You may also place this inside of a function,
// and execute it when you desire, but `onload` is not going
// to fire by itself, when inside of document.ready
alert(getParameterByName('txt_temp'));
alert(getUrlVars()["txt_temp"]);
});
This should get you started:
function parseQueryStr( str, obj ) {
// Return object
obj = obj || {};
// Looping through our key/values
var keyvalues = str.split('&');
for( var i=0; i<keyvalues.length; i++ ) {
// Break apart our key/value
var sides = keyvalues[i].split( '=' );
// Valid propery name
if( sides[0] != '' ) {
// Decoding our components
sides[0] = decodeURIComponent( sides[0] );
sides[1] = decodeURIComponent( sides.splice( 1, sides.length-1 ).join( '=' ) );
// If we have an array to deal with
if( sides[0].substring( sides[0].length - 2 ) == '[]' ) {
var arrayName = sides[0].substring( 0, sides[0].length - 2 );
obj[ arrayName ] = obj[ arrayName ] || [];
obj[ arrayName ].push( sides[1] );
}
// Single property (will overwrite)
else {
obj[ sides[0] ] = sides[1];
}
}
}
// Returning the query object
return obj;
}
var href = window.location.href.split('#');
var query = href[0].split('?');
query.splice(0,1);
var get = parseQueryStr(query.join('?'));
alert( get.txt_temp );
You can use:
var param = new URLSearchParams(urlString).get('theParamName');
Or if searching the current page:
var param = new URLSearchParams(location.search).get('theParamName');
you have to slice the everything before and after "=" so first answer is a bit incomplete. Here is the answer which works for querystrings includes "=" in it too :) Like:
https://localhost:5071/login?returnUrl=/writer/user?id=315&name=john
Thanks to user abhi
var getUrlVars = function () {
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]); //to get name before =
vars[hash[0]] = hashes[i].slice(hashes[i].indexOf('=') + 1); //to take everything after first =
}
return vars;
}
and then get it with
var url = window.getUrlVars()["returnUrl"];
so it will extract "/writer/user?id=315" with "=" too :)
I wrote this one liner with ES6 syntax which follows the method of the accepted answer.
function getParam(key){
return window.location.href.split('?')[1].split('&').filter(x=>x.split('=')[0]==key)[0].split('=')[1];
}
Use:
Lets say the current URL is: https://stackoverflow.com?question=30271461
getParams('question') //30271461
I want to add properties to an object and pass that object to another page.
A few things:
I would combine the functions in a namespace;
you don't need Base64 encoding, since encodeURIComponent() will suffice;
This is not suitable for large objects, you would need localStorage for that;
Your code had a few gotchas, such as when an href already contains a ?;
I've reworked it like so:
DataTransferService = {
sendToUrl: function(obj, url, name) {
var value = JSON.stringify(obj);
name = name || 'data';
return url + (url.indexOf('?') === -1 ? '?' : '&') + name + '=' + encodeURIComponent(value);
},
receiveFromCurrentUrl: function(name) {
return receiveFromUrl(window.location.href, name);
},
receiveFromUrl: function(url, name) {
var value;
name = name || 'data';
url = url || window.location.href;
if ((value = this.getUrlParameter(name, url)) !== null) {
return JSON.parse(value);
}
},
getUrlParameter:function(name, url) {
var p, qs;
if ((p = url.indexOf('?')) === -1) {
return null;
}
qs = url.substr(p + 1).split('&');
for (var i = 0, len = qs.length; i != len; ++i) {
var pair = qs[i].split('=');
if (pair[0] === name) {
return decodeURIComponent(pair[1]);
}
}
return null;
}
};
To use:
var obj = {
a: 123,
b: 456,
c: [1, 3, 5]
};
var url = DataTransferService.sendToUrl(obj, '/path/to/page');
// "/path/to/page?data=..."
location = url;
On the receiving page:
var obj = DataTransferService.receiveFromCurrentUrl();
// work with obj here
Functions to put in your global js file..
function GotoPage(relUrl) {
var json = JSON.stringify({param1:val1, param2:val2});
window.location.href = relUrl.concat('?data=').concat(Base64.encode(json));
}
function GetUrlVars() {
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
Assume we're navigating from page1 to page2.. in page2's .js file you'll write:
var base64data = GetUrlVars()['data']
var jsondata = Base64.decode(base64data)
var data = JSON.parse(data);
var param1 = data.param1;
//do something with the objects properties
For the Base64 implementation see: How can you encode a string to Base64 in JavaScript?
Now that i learned how to pass values to an SWF object via flashvars, could you please guide me how can i pass values from a querystring to javascript?
What do i mean? In the following example i hard-code the xml file to load in the SWF object.
<script type="text/javascript">
var so = new SWFObject("preview.swf", "", "100%", "100%", "9", "#ffffff");
so.addParam("allowFullScreen", "true");
so.addParam("scale", "noscale");
so.addParam("menu", "false");
so.addVariable("xmlPath", "xml/exampleData.xml");
so.write("flashcontent");
</script>
Since the Xml file is created dynamic, the xml should be loaded from the value of a query-string. (I guess).
Supposing my url is http://www.example.com/load.aspx?XmlFile=SomeData
How can i pass it to the javascript side? Like..
so.addVariable("xmlPath", "xml/<% SomeData %>.xml");
or whatever it needs to make it work.
UPDATE: Besides the above example, is there any way of creating the JavaScript, in server-side?
Try something like:
function GetQueryString(param)
{
var url = window.location.search.substring(1);
var params = url.split("&");
for (i=0;i<params.length;i++)
{
var p = params[i].split("=");
if (p[0] == param)
{
return p[1];
}
}
}
And use it like:
so.addVariable("xmlPath", "xml/" + GetQueryString("XmlFile") + ".xml");
window.location.href contains the querystring of the current page, this should work:
// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
function getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
