I'm trying to dynamically load images from a certain post type. I've used the Advanced Custom Fields plugin to attach an image field to my post. I'm currently using this code:
$.getJSON('/?json=get_recent_posts&post_type=slides-verhuur&custom_fields=image', {}, function(data){
console.log(data);
});
However when I run the code, the result JSON I get contains a "custom field" attribute, which have an "image" attribute, but this only contains the value of "80", which is the ID of the image. Is there a way to get the image url instead?
You need to set Return Value as "Image URL" instead of "Image ID" Under Custom Fields group a image field as per image shown below.
$post_response->data['CFS'] = CFS()->get(false, $page->ID, array('format' => 'api'));
use 'api' instead of 'raw'

Is it possible to prevent the data from being automatically passed to the input fields. For example - if I have an edit page where I want to change the data and I want the user to type the data again without giving him the pre-filled old data. I was looking over some documentation about the ModelState and the asp-for tag but I just couldn't find the answer.
I was looking for help and I found this post here. Well I want to do exactly the opposite.
asp-for tag helper functionality_
EDIT:
I tried to change the value attribute of the input field to empty string and it worked, however I still would like to know if there is an asp.net approach.
If you don't want to pass data from action to Edit view,you can return a view with an empty model like this:
public IActionResult Edit()
{
return View(new YourModel());
}
Or you can try to use id and name attribute to replace asp-for,so that the data will not be binded to inputs.Here is a demo.
Change
<input asp-for="TestProperty" />
to
<input id="TestProperty" name="TestProperty" />
I wish to display the JSON response returned from a REST API call "as-is" on a JSP. The problem I'm facing here is that the response is in a single line like below.
{"result":[{"enable":"true","time_stamp":"2018-01-26 19:31:37","url":"abc.xyz.com","group_id":"one"},{"enable":"false","time_stamp":"2018-01-26 19:31:37","url":"lmn.pqr.com","group_id":"two"}]}
I would like it to be displayed in a well-formatted JSON response, something like below for sorts.
{
"result":[
{
"enable":"true",
"time_stamp":"2018-01-26 19:31:37",
"url":"abc.xyz.com",
"group_id":"one"
},
{
"enable":"false",
"time_stamp":"2018-01-26 19:31:37",
"url":"lmn.pqr.com",
"group_id":"two"
}
]
}
Having said that, there are certain url ("url":"abc.xyz.com")parameters in the JSON response, which I would want to be clickable, so that users can see the JSON response dumped on the web page, but be able to click on the URL field's value to navigate to the different page.
Any idea of how this could be achieved?
Just use JSON.stringify and a HTML tag of pre
Here is a fiddle demo
or if your use AngularJs use:
<pre>{{jsonData|json}}</pre>
I am parsing or reading a JSON file in my AngularApp. I want to create one template for each object inside the JSON file, and then load it with "previous" and "next" in my app.
So i have a JSON file, for example:
{
"name": "test",
"objects":[
{"one": "text here", "id" : "1" },
{"two": "and text there", "id" : "2" }
]
}
So i want to create a template called "template1" and "template2".
I am starting with Angular, so i don't need a whole workaround, just where do i have to dig deeper?
I created a controller for my app
I've then created a jsonService which injectes the controller
Now i have the JSON data
But what then? Do i have to create Directives? And how to load them into my main-page? With data-ng-view?
See this example which will give you an example of how you can iterate over json and render to html:
https://github.com/eu81273/angular.treeview/blob/master/angular.treeview.js
Thanks #Nikos for this possibility. I found a much simpler soultion:
I hard coded a ng-switch on="option" and then a ng-switch-when="optionN" in each div, so i can dynamically adjust one template to fit all options.
I want to render some json data using HTML template.
I haven't started implementing anything yet, but I would like to be able to "set" values of data from json to html element which contains template for one record, or to render some collection of items using some argument which is template html for each item, but also to be able to get JSON object back in same format as source JSON which was used to render item (I want my initial JSON to contain some more information about behavior of record row, without the need to make ajax request to check if user can or can't do something with this record, and not all of this info is visible in template).
I know that I could make hidden form with an input element for each property of object to store, and mapper function to/from JSON, but it sounds like overkill to me, and I don't like that, I want some lighter "envelope".
I was wondering is there some JS library that can "serialize" and "deserialize" JSON objects into html so I can store it somewhere in DOM (i.e. in element which contains display for data, but I want to be able to store additional attributes which don't have to be shown as form elements)?
UPDATE As first answer suggested storing JSON in global variable, I also have thought about that, and my "best" mental solution was to make JavaScript module (or jQuery plugin) which would do "mapping" of JSON to html, and if not possible to store values in html then it can store them in internal variable, so when I want to "get" data from html element it can pull it from its local copy. I want to know is there better way for this? If there is some library that stores this info in variable, but does real-time "binding" of that data with html, I would be very happy with that.
UPDATE 2 This is now done using http://knockoutjs.com/, no need to keep json in DOM anymore, knockout does the JSON<=>HTML mapping automatically
Why not store it as nature intended: as a javascript object? The DOM is a horrible place.
That said, jQuery has the data method that allows just this.
So you want to keep a reference to the JSON data that created your DOMFragment from a template?
Let's say you have a template function that takes a template and data and returns a DOM node.
var node = template(tmpl, json);
node.dataset.origJson = json;
node.dataset.templateName = tmpl.name;
You can store the original json on the dataset of a node. You may need a dataset shim though.
There is also no way to "map" JSON to HTML without using a template engine. Even then you would have to store the template name in the json data (as meta data) and that feels ugly to me.
I have done this in the past as well in a couple of different ways.
The $('selector').data idea is probably one of the most useful techniques. I like this way of storing data because I can store the data in a logical, intuitive and orderly fashion.
Let's say you have an ajax call that retrieves 3 articles on page load. The articles may contain data relating to the headline, the date/time, the source etc. Let's further assume you want to show the headlines and when a headline is clicked you want to show the full article and its details.
To illustrate the concept a bit let's say we retrieve json looking something like:
{
articles: [
{
headline: 'headline 1 text',
article: 'article 1 text ...',
source: 'source of the article, where it came from',
date: 'date of the article'
},
{
headline: 'headline 2 text',
article: 'article 2 text ...',
source: 'source of the article, where it came from',
date: 'date of the article'
},
{
headline: 'headline 3 text',
article: 'article 3 text ...',
source: 'source of the article, where it came from',
date: 'date of the article'
}
]
}
From an ajax call like this . . .
$.ajax({
url: "news/getArticles",
data: { count: 3, filter: "popular" },
success: function(data){
// check for successful data call
if(data.success) {
// iterate the retrieved data
for(var i = 0; i < data.articles.length; i++) {
var article = data.articles[i];
// create the headline link with the text on the headline
var $headline = $('<a class="headline">' + article.headline + '</a>');
// assign the data for this article's headline to the `data` property
// of the new headline link
$headline.data.article = article;
// add a click event to the headline link
$headline.click(function() {
var article = $(this).data.article;
// do something with this article data
});
// add the headline to the page
$('#headlines').append($headline);
}
} else {
console.error('getHeadlines failed: ', data);
}
}
});
The idea being we can store associated data to a dom element and access/manipulate/delete that data at a later time when needed. This cuts down on possible additional data calls and effectively caches data to a specific dom element.
anytime after the headline link is added to the document the data can be accessed through a jquery selector. To access the article data for the first headline:
$('#headlines .headline:first()').data.article.headline
$('#headlines .headline:first()').data.article.article
$('#headlines .headline:first()').data.article.source
$('#headlines .headline:first()').data.article.date
Accessing your data through a selector and jquery object is sorta neat.
I don't think there are any libraries that store json in dom.
You could render the html using the data from json and keep a copy of that json variable as a global variable in javascript.
i am using slideshow2 by Aeron Glemann in a website.Does in generate the thumbnails or do i have to provide them?the images iam showing are coming from a cloud, and are passed to the slideshow in an array.the thumbs exist in the cloud. how can i pass them in the array if the show cannot create them?
i have used the replace parameter with regex but it shows as thumbnails the full image and nothing happens when i alter the css properties for the thumbnails. the images are displayed.
here is the line for the show creation:
var myShow = new Slideshow('show', eval(res.value), { controller: true, height: 350,overlap: false, resize: false, hu: '',replace:[/^\S+.(gif|jpg|jpeg|png)$/,'t$1'],thumbnails: true, width: 600});
the value object contains the images from the cloud in format shown below:
['xx.jpg','yy.png',....]
thank you very much for your time.
I'd say your regular expression is broken. To add a 't' to the end of the filename? Try:
replace:[/^(\S+)\.(gif|jpg|jpeg|png)$/,'$1t.$2']
Best to play with the regular expression using an online tester to get it right.
