I have meet with a problem.
In my view I use a span to bind my string.
<span data-bind="text: myString"></span>
In the model:
myString = '<b>I want Show in Bold!</b>';
It always show the origin string in my view.So how to make the view know it is a HTML tag?
Use html binding as per docs
<span data-bind="html: myString"></span>

I have these lines of code:
<span
class="close-modal"
onclick="#Html.Action("SaveNotes", "CallCenter", new { activityId = item.callIdKey, noteText = "test1" })">
×
</span>
Notes: <br />
<textarea name="paragraph_text" rows="5" style="width:90%">
#item.NoteText
</textarea>
I would like to replace test1 from the noteText route variable and instead change it to whatever the value in the <textarea> tag is.
Is there an elegant way of doing this without writing a giant block of jQuery code?
#Html.Action() renders a partial view as an HTML string during page processing (on the server side). It doesn't exist any more in the markup, once the page is sent to the browser. You can't do what you are trying to do this way. At the very least, I'm sure you don't want to render a partial view inside the onclick event of your <span> tag.
Why not instead use an HTML helper for the <textarea> tag? Then you can get whatever value the user typed into it on the server code. You'll want to make the form post itself back to the server on the close-modal element:
<span class="close-modal" onclick="$('form').submit()">×</span>
<form method="post" action="#Url.Action("SaveNotes", "CallCenter", new { activityId=item.callIdKey }">
Notes: <br />
#Html.TextArea("noteText", item.NoteText, new { rows="5", style="width:90%" })
</form>
This assumes you have jQuery already (a common assumption with ASP.NET). You may not need the <form> tags if you already have a form on your page.
A #gunr2171 notes in the comments, the only way to dynamically update a link once it's been rendered to the browser is via some form of client-side scripting, typically JavaScript. In your case, I'd recommend doing something like this:
<span
class="close-modal"
data-href-template="#Url.Action("SaveNotes", "CallCenter", new {activityId = item.callIdKey, noteText="{note}"})"
>
×
</span>
Note: As #HBlackorby notes in his answer, you shouldn't be using #Html.Action() here; I assume you meant #Url.Action().
This way, your JavaScript has a template (data-href-template) that it can work against with a clearly defined token ({note}) to replace, instead of needing to parse the URL in order to identify where the previously replaced text is. Otherwise, you potentially end up in a scenario where you type e.g. CallCenter into your <textarea /> and it's now an ambiguous reference that you can't just blindly replace. Or, worse, you type 'a' and it's really ambiguous.
If you are already using jQuery on your site, the actual replacement might be done using something along the lines of:
$(document).ready(function () {
$('span.close-modal').click(function() {
var noteInput = $('textarea[name="paragraph_text"]');
var encodedNote = encodeURI(noteInput.text());
var template = $(this).data("href-template");
var targetUrl = template.replace("{note}", encodedNote);
window.location.href = targetUrl;
});
});
You can also do this without jQuery, obviously—and should if you're not already depending on it. The point is to illustrate that this doesn't necessarily need to be a "giant block of jQuery code". In fact, this could be done in just a few lines—and probably should be. I deliberately broke it out into multiple steps and variables for the sake of readability.
If I have this AngularJs code:
<div class="myStyle">
TITLE:
{{product.title}}
</div>
I want show title without encode. so I know it's one solution:
<div class="myStyle">
TITLE:
<span ng-bind-html="product.title"></span>
</div>
But I don't happy about extra <span> code!
Also if I have this code:
<img src="img.jpg" alt="{{product.title}}">
I can not use extra span, Now how can I show title in alt tag of image without encode?!
I am assuming that since you use ng-bind-html that product.title is html string , not text
You could create a custom filter that returns text from html string
app.filter('htmlToText', function(){
return function(html){
return angular.element('<div>').append(html || '').text();
};
});
View
<img src="img.jpg" alt="{{product.title | htmlToText}}">
For showing product.title in div, if you don't like the extra span, you might try:
<div class="myStyle" ng-bind="product.title"></div>
where in your javascript code, you can add a prefix: "Title: " to product.title. (Although i don't feel having an extra span is bad)
Another side note, I see you are using ng-bind-html. Is "product.title" really html? If it contain some styles, maybe you can revise your "myStyle" to control the style. Let data be data.
For the image one, you probably don't need to worry about the {{ }}.
I am guessing the reason you don't like {{ }} is they may show briefly before angular can render the template with the data. However, if you put them in , the browser will not show content inside of alt unless your image is not available (If the image is really not available, you may consider revisiting your codes to make sure it is available, or to display a default image)
I am trying to get parse HTML document.
this is the HTML:
<h1>
<span class="memName fn" itemprop="name">Ankur Arora</span>
<span class="display-none" itemprop="image">http://photos1.meetupstatic.com/photos/member/3/8/f/8/member_249974584.jpeg</span>
<span class="display-none" itemprop="url">http://www.meetup.com/Meetup-API-Testing/members/191523682/</span>
</h1>
I need to get the picture and the name.
I try this code:
var name = document.querySelector("memName fn").name;
Anyone can help me? I'm new in javaScript...
Thanks
To get the inner text, you can use the text() function, like this:
HTML:
<span class="memName fn">Ankur Arora</span>
Jquery:
var memName = $(".memName").text();
console.log(memName); // Via console log
alert(memName); // Alert it
It's easy with jQuery. Just include it in your page:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
Then use .text() or .html() to extract the content of the span-elements
var pictureLink = $("span[itemprop='image']").text();
//.html() also gets the html-elements inside
var name = $("span[itemprop='name']").html();
https://jsfiddle.net/bh9mebru/
You can also use innerHTML to get the text.
<span id="memId" class="memName fn">Ankur Arora</span>
document.getElementsByClassName('memName') - This will give the list of elements having the class 'memName'
To get the first element's inner text use document.getElementsByClassName('memName')[0].innerHTML
or access by id .
document.getElementById('memId').innerHTML
I have a JSON file which contains multiple <br /> tags. The file is parsed using JSON.parse(json) into an object. Because I bind the data with AngularJS and ng-repeat I don't want that the strings have any HTML tags and replace it with a new line \n. How can I replace all tags? It seems to me that replace() only works with strings.
Thanks for your help!
JSON example
{
"title": "Title",
"description": "This<br />is<br />a<br />description."
}
JavaScript
var retrievedObject = JSON.parse(json);
$scope.data = retrievedObject;
HTML
<div ng-repeat="item in data">
{{item.description}}
{{item.description}}
</div>
You could just replace it before you parse the string
var retrievedObject = JSON.parse(json.replace(/\<br \/\>/g, ''));
A better option would be to parse the strings as HTML and extract the text without the tags, not using a regex before you insert them in the DOM
There's two ways to do what you're looking for. One with css where you replace the br's with
\n and then in your css file give the element the white-space property of pre-wrap.
The other is angularish. Take a read of data-ng-bind-html. You'd be able to actualy have the br's outputted. https://docs.angularjs.org/api/ng/directive/ngBindHtml You would have to run it through a filter of $sce so that it's trusted but your code would be as simple as:
<div ng-repeat="item in data">
<span data-ng-bind-html="item.description | trusted"></span>
<span data-ng-bind-html="item.description | trusted"></span>
</div>
your filter for trusted would be this:
.filter("trusted", function($sce){
return function(input){
return $sce.trustAsHtml(input);
}
});
ngBindHtml will let you keep keep the <br>s and render newlines in your HTML. It will automatically sanitize your input using ngSanitize to strip out any tags are aren't in its whitelist (you have to bring ngSanitize in as a dependency)...
var app = angular.module("app", ["ngSanitize"]);
The view is as simple as...
<div ng-bind-html="item.description"></div>
JsBin
You can also use $sce.trustAsHtml() to tell ngBindHtml to blindly trust the HTML without sanitizing, but only do that if you can completely trust its content (i.e., not for things like user submitted comments, etc).
I have a span tag like this and stored in the variable "foo"
<span class="right margin">
سی ئی 1500
<br>
Nicole Kidman
</span>
Using jQuery OR javascript, how can I change the "Nicole Kidman" clause with something I want? innerHTML changes everything in the <span>
Edit: I edited the text with this code foo[0].lastChild.nodeValue="something else"; but is there another way doing that using only jQuery?
I recommend you add another span tag around Nicole Kidman.
<span class="right margin">
سی ئی 1500
<br>
<span>Nicole Kidman</span>
</span>
and change the text like this:
$(".right").find("span").text("something you want");
<span> is an inline element. We avoid using <br/> in them.
It is also advisable to use another tag to encapsulate your 'Nicole Kidman' text.(Like another <span>)
I'm not aware of your entire HTML structure so I'm going with what you have posted. Here is a fiddle example for how it can be done.
Here the foo is not a jQuery object:
foo.lastChild.textContent='something you want'
So the foo is a jQuery object, but you still need to access the dom element directly:
foo.contents().eq(-1).textContent='something you want'
