I'm trying to get the value of the first 'price' field at the url:
http://pubapi.cryptsy.com/api.php?method=singleorderdata&marketid=132
I am currently using the following code to do so:
getJSON('http://pubapi.cryptsy.com/api.php?
method=singleorderdata&marketid=132').then(function(data) {
var final = (data.return.DOGE.sellorders.price * totalcost) * 0.985
var finished = final.toFixed(8)
I have a strong feeling that I have done this bit wrong:
data.return.DOGE.sellorders.price
Any ideas?
Thanks!
data.return.DOGE.sellorders[0].price because sellorders is an array
$.getJSON('http://jsbin.com/pudoki/1.json', function(data){
alert(data.return.DOGE.sellorders[0].price);
});

I use ajax get a json like this:
{"dataStore":"[{\"delete_flag\":\"false\",\"id\":\"74\",\"icon_img\":\"img/a5.jpeg\"}]"}
How to append "delete_flag" , "id" , "icon_img" to 3 different places on html ?
You can use this pure javascript method like below.
The code basically uses document.getElementById() to get the element, and .innerHTML to set the inside of the element to the value of the object.
This code (and the code using jQuery) both use JSON.parse() to parse the data into the correct object that our code can read. The [0] at the end is to select the object we wanted since it would give us an array (and we want an object).
const result = {"dataStore":"[{\"delete_flag\":\"false\",\"id\":\"74\",\"icon_img\":\"img/a5.jpeg\"}]"};
const parsedData = JSON.parse(result.dataStore)[0];
document.getElementById("delete_flag").innerHTML = parsedData.delete_flag;
document.getElementById("id").innerHTML = parsedData.id;
document.getElementById("icon_img").src = parsedData.icon_img;
<div id="delete_flag"></div>
<div id="id"></div>
<img id="icon_img">
Or you can use jQuery (which in my opinion, is much simpler). The code below uses .html() to change the inside of the divs to the item from the object, and .attr() to set the attribute src to the image source you wanted.
const result = {"dataStore":"[{\"delete_flag\":\"false\",\"id\":\"74\",\"icon_img\":\"img/a5.jpeg\"}]"};
const parsedData = JSON.parse(result.dataStore)[0];
$("#delete_flag").html(parsedData.delete_flag);
$("#id").html(parsedData.id);
$("#icon_img").attr("src", parsedData.icon_img);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="delete_flag"></div>
<div id="id"></div>
<img id="icon_img">
you can use jQuery .html() or .text()
For example:
var json = {"id" : "74"};
$( "#content" )
.html( "<span>This is the ID: " + json.id + "</span>" );
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<div id="content"></div>
</body>
</html>
Just use some simple JavaScript parsing:
const jsonData = {"dataStore":"[{\"delete_flag\":\"false\",\"id\":\"74\",\"icon_img\":\"img/a5.jpeg\"}]"};
const parsedData = JSON.parse(jsonData.dataStore)[0];
document.getElementById("delFlag").textContent = "Delete Flag: " + parsedData["delete_flag"];
document.getElementById("id").textContent = "ID: " + parsedData["id"];
document.getElementById("img").textContent = "Image: " + parsedData["icon_img"];
<p id="delFlag"></p>
<p id="id"></p>
<p id="img"></p>
Note that you can't parse the full object jsonData because it's not JSON - only the data inside it is JSON.
I've upvoted the other answers, but maybe this will help someone else. On your ajax success function, do something like this:
success: function(data){
// console.log('succes: '+data);
var delete_flag = data['delete_flag'];
$('#results').html(delete_flag); // update the DIV or whatever element
}
if you got real fancy, you could create a for loop and put all the json variable you need into an array and create a function to parse them all into their proper elements; you could learn this on your own fairly easily.
var data = {
"dataStore": {
"delete_flag": "false",
id: "74"
}
}
$('.flag').html(data.dataStore.delete_flag);
$('.id').html(data.dataStore.id);
span {
color: red
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Flag: <span class="flag"></span>
<hr />
ID: <span class="id"></span>
Need to dynamically update contents in a div of main page, based on data fetched from other html page
setInterval( function() {
$.ajax({
type:'GET',
url:"url for status",
success : function(data){
console.log(data);
}
})
},3000);
The content of 'data' printed in developer tool console is:
<html>
<style>
</style>
<head>
</head>
<script>
var conns=[{num:1,
id:1,
Conn:[{type:'ppp',
Enable:1,
ConnectionStatus:'Disconnected',
Name:'CONNECTION_1',
Uptime:0,
ConnectionError:'TIME_OUT',
..............
}]
},
{num:2,
id:2,
Conn:[{type:'ppp',
Enable:1,
ConnectionStatus:'Disconnected',
Name:'CONNECTION_2',
Uptime:0,
ConnectionError:'TIME_OUT',
..............
}]
}]
</script>
</html>
Need to extract the ConnectionStatus, Name and ConnectionError from this content and display it in respective div in main page.
I would recommend using a different transfer type, however, you could use something like this:
function break_out_each_id(){//returns array of indexes where id starts
var i = 0;
id_objs = [];
while data.indexOf('id', i) > -1{
id_objs[i] = data.indexOf('id', i);
i++;
}
return id_objs
}
function find_values(){//pseudo code
use the array of indexes from first index to next index
in that string, do index of each value you are looking for (ConnectionStatus...)
then parse that line after the ':' to get the value.
Do this for each index in indexes array
}
Sorry for the pseudo code, but this post is getting really long. Like I said, it would be MUCH better to just send the response as JSON (even if it is a stringified version of it). In that case you could just do a simple JSON.parse() and you'd be done.
i started work with LINQ in javascript using http://jslinq.codeplex.com/ where it is suggested to add package jslinq. I added it and started with following query
var exampleArray = JSLINQ(myList)
.Where(function(item){ return item.FirstName == "Chris"; })
.OrderBy(function(item) { return item.FirstName; })
.Select(function(item){ return item.FirstName; });
but while debugging, on first line (var exampleArray = JSLINQ(myList)) shown error like 'uncought reference error JSLINQ not defined'..
please inform me what i am missing.. i am completely new to this.. thanks in advance.
Have You added
<SCRIPT type="text/javascript" src="/scripts/JSLinq.js"></SCRIPT>
before you call JSLINQ(myList) ?
I have a list like this which I the server gives to the template:
test_data/reads_1.fq
test_data/reads_2.fq
test_data/test_ref.bt2
test_data/test_ref.ebwt
test_data/test_ref.fa
test_data/test_ref2.bt2
test_data/new_directory/ok.txt
I want to show these files in a tree view like this:
test_data
reads_1.fq
reads_1.fq
test_ref.bt2
test_ref.ebwt
test_ref.ebwt
new_directory
ok.txt
What's the best possible way to do like this? Thanks
Edit
I am sending my data like this as a list(Python):
['test_data/reads1.fq', 'test_data/reads_2.fq', test_data/new_directory/ok.txt]
Edit2
$(document).ready(function(){
var string=["test_data/new_directory/ok.txt","test_data/reads_1.fq","test_data/test_ref.fa"];
for(var i=0;i<string.length;i++){
var result = string[i].split('/');
$('html').html('<ul><li>'+result[0]+'</li><ul><li>'+result[1]+'</li><ul><li>'+result[2]+'</li></ul></ul>');
}
});
Result
test_data
test_ref.fa
undefined
Expected Result:
test_data
reads_1.fq
reads_2.fq
new_directory
ok.txt
Try this:
<script type="text/javascript">
$(document).ready(function(){
var string=["test_data/new_directory/ok.txt","test_data/reads_1.fq","test_data/test_ref.fa"];
for(var i=0;i<string.length;i++){
var result = string[i].split('/');
console.log(result);
}
});
</script>
it may not be the best practice, but you need something like this. You also may put your string into array to check whether indexes are the same to avoid the repetition. If I ave time I will look into this properly.
I'm new in Jquery, I would like to have Jquery code to get the current page url and if the url contains certain string then load remote element.
example:
i have the page urls like this:
"http://......./Country/AU/result-search-to-buy"
"http://......./Country/CA/result-search-to-buy"
"http://......./Country/UK/result-search-to-buy"
the part "/Country/AU" is what I need to determine which page element I should load in, then if "AU" I load from "/state-loader.html .state-AU", if "CA" I load from "/state-loader.html .state-CA"
I have a builtin module "{module_pageaddress}" to get the value of the current page url, I just dont know the Jquery logic to let it work.
I expect something like this:
if {module_pageaddress} contains "/Country/AU/"
$('#MyDiv').load('state-loader.html .state-AU');
if {module_pageaddress} contains "/Country/CA/"
$('#MyDiv').load('state-loader.html .state-CA');
please help and many thanks.
Here is some code:
<!DOCTYPE html>
<html>
<head>
<title>jQuery test page</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
function loadContent(elementSelector, sourceURL) {
$(""+elementSelector+"").load(""+sourceURL+"");
}
function stateURL() {
var startOfResult = '../../state-loader.html #state-';
var match = (/(?:\/Country\/)(AU|US|CA|UK)(?:\/)/).exec(window.location.pathname);
if (match) {
return startOfResult + match[1];
} else {
return startOfResult + 'AU';
}
}
</script>
</head>
<body>
Link 1
<div id="content">content will be loaded here</div>
</body>
</html>
And the file to load the different content for the states:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div id="state-US">Go USA!</div>
<div id="state-CA">Go Canada!</div>
<div id="state-AU">Go Australia!</div>
<div id="state-UK">Go United Kingdom!</div>
</body>
</html>
See it work here:
http://www.quirkscode.com/flat/forumPosts/loadElementContents/Country/US/loadElementContents.html
Replace .../US/... with .../AU/..., etc. to see how it behaves.
Original post where I got the ideas/original code:
http://frinity.blogspot.com/2008/06/load-remote-content-into-div-element.html
You can try
var countryCode = ... // parse the country code from your module
$('#yourDiv').load('state-loader.html .state-' + countryCode);
See more examples of .load() here.
As far as pulling the url path you can do the following
var path_raw = document.location.path,
path_array = path_raw.split("/");
Then, you could do something like this:
$.ajax({
url: "./remote_data.php?country=" + path_array[0] + "&state=" + path_array[1],
type: "GET",
dataType: "JSON",
cache: false,
success: function(data){
// update all your elements on the page with the data you just grabbed
}
});
Use my one line javascript function for getting an array of the URL segments: http://joshkoberstein.com/blog/2012/09/get-url-segments-with-javascript
Then, define the variable $countrySegment to be the segment number that the country code is in.
For example:
/segment1/segment2/CA/
(country code would be segment 3)
Then, check if the 3rd array index is set and if said index is either 'CA' or 'AU'. If so, proceed with the load, substituting in the country-code segment into the .html filename
function getSegments(){
return location.pathname.split('/').filter(function(e){return e});
}
//set what segment the country code is in
$countrySegment = 3;
//get the segments
$segments = getSegments();
//check if segment is set
//and if segment is either 'AU' or 'CA'
if(typeof $segments[$countrySegment-1] !==undefined && ($segments[$countrySegment-1] == 'AU' || $segments[$countrySegment-1] == 'CA')){
$countryCode = $segments[$countrySegment-1];
$('#target').load('state-loader.html .state-' + $countryCode);
}
var result= window.location.pathname.match(/\/Country\/([A-Z]+)\//);
if(result){
$('#MyDiv').load('state-loader.html .state-' + result[1]);
}
