iframe is loaded dynamically into container div inside function.
With cc.text(content); I try to update #code content.
I check changed text in runtime, it's updated but on screen value remains the same.
I am not a javascript pro, so any comments are welcome:
function ShowEditor(content) {
var url = "XmlEditor/Editor.htm";
slHost.css('width', '0%');
jobPlanContainer.css('display', 'block');
frame = $('<iframe id="' + jobPlanIFrameID + '" src="' + url + '" class="frame" frameborder="0" />');
frame.appendTo(jobPlanIFrameContainer);
$(frame).load(function () {
var ifr = frame[0];
var doc = ifr.contentDocument || ifr.contentWindow.document;
var jdoc = $(doc);
var cc = jdoc.contents().find("#code");
// var tst = cc.text();
// alert(tst);
cc.text(content);
});
}
I get the text in commented code, but fail to update #code content.
iframe holds the following html where I omit details inside head and script:
<!doctype html>
<html>
<head></head>
<body>
<form>
<textarea id="code" name="code">some texts</textarea>
</form>
</body>
</html>
Your XML editor doesn't read more than once what's in the textarea.
A simple solution would be to generate in javascript the iframe content with the desired textarea content instead of loading it and then try to change the textarea content.
In fact (depending on the capacities of your XML Editor), you probably can do that directly in a generated text area instead of using a whole iframe to do it.

I have been struggling with this so hopefully someone can help!
So I am looking to change the inner html of a paragraph to another html element containing a div and script when my frame receives a message from the page code. I have this working only for when the inner html is set to replace with a normal string
like this
document.getElementById('demo').innerHTML = "testing" ;
the correct replacement shows up here
<p id="demo">testing</p>
but when I try and pass in the other html to replace that section like this:
document.getElementById('demo').innerHTML =
'<div id="tlkio" data-channel="regerhtrh" data-theme="theme--night" style="width:100%;height:400px;"></div><script async src="https://tlk.io/embed.js" type="text/javascript"></script>';
it does not work. I don't think it is a quotation issue because I wrapped the outsides of it with single quotes. not sure what else to try. Below is the full html and I would appreciate any help!
<!doctype html>
<html>
<head>
<script type="text/javascript">
function init () {
// when a message is received from the page code
window.onmessage = (event) => {
if (event.data) {
console.log("HTML Code Element received a message!");
insertMessage(event.data);
}
}
}
// display received message
function insertMessage(msg) {
document.getElementById('demo').innerHTML =
'<div id="tlkio" data-channel="regerhtrh" data-theme="theme--night" style="width:100%;height:400px;"></div><script async src="https://tlk.io/embed.js" type="text/javascript"></script>'
;
}
</script>
</head>
<body onload="init();" style="background-color:lightgray;">
<h1>HTML Component Test</h1>
<p id="demo">
should put html here
</p>
</body>
</html>
The major issue is the </script> closing tag in your code. It closes YOUR block, not the block you are inserting.
You have to do so:
var myHtml = "<div id='tlkio' data-channel='regerhtrh' data-theme='theme--night' style='width: 100%; height:400px;'></div><script async src='https://tlk.io/embed.js' type='text/javascript'></scr"+"ipt>";
Second, script you insert with innerHTML wont run. Use document.createElement('script') instead
UPDATE
Here is the jsFiddle: https://jsfiddle.net/ArtyomShegeda/62fdybc0/21/
You may consider swapping the Quotes used:
function insertMessage(msg) {
var myHtml = "<div id='tlkio' data-channel='regerhtrh' data-theme='theme--night' style='width: 100%; height:400px;'></div><script async src='https://tlk.io/embed.js' type='text/javascript'></script>";
document.getElementById('demo').innerHTML = myHtml;
}
This may add it, yet may not render it. You might consider creating the elements and appending them.
function insertMessage(msg) {
var tlkio = document.createElement("div");
tlkio.style.width = "100%";
tlkio.style.width = "400px";
tlkio.setAttribute('data-channel', 'regerhtrh');
tlkio.setAttribute('data-theme', 'theme--night');
var tlkScript = document.createElement("script");
tlkScript.src = 'https://tlk.io/embed.js';
tlkScript.type = 'text/javascript';
tlkScript.async = true;
document.getElementById('demo').append(tlkio, tlkScript);
}
Based on some research here: load scripts asynchronously, it may be best to append the script to the <head>.
Hope that helps.
Update 1
Per your fiddle, once updated, it is working as you suggested: https://jsfiddle.net/Twisty/62fdybc0/7/
The following is added to #myDIV element:
<div style="width: 100%; height: 400px;" data-channel="regerhtrh" data-theme="theme--night"></div><script src="https://tlk.io/embed.js" type="text/javascript" async="async"></script>
I have a JavaScript program that gets the last modified date of a txt file. The code works fine in Firefox but for some reason, it does nothing in IE11. My code is listed below.
JavaScript code:
function getLastMod(){
var myFrm = document.getElementById('myIframe');
var lastMod = new Date(myFrm.contentWindow.document.lastModified);
var getSpan = document.getElementById('LastModified');
getSpan.innerHTML += "<font color=red> (File Last Updated: " + lastMod.toLocaleString() + ")</font>";
}
HTML code:
<span id="LastModified"></span>
<iframe id="myIframe" onload="getLastMod()" src="date.txt" style="display:none;"></iframe>
I had a similar issue when I tried to define the event in the tag. I had better results assigning the event from within javascript.
<script type="text/javascript">
document.getElementById('myIframe').onload = function() {
getLastMod();
}
</script>
I'm working on a form builder website. After a form is built it must be saved in database. When the user clicks on a form name from the list of saved forms the form information is restored from database. One of the variables I will restore is the structure of the form. In javascript I wrote these lines of code:
var prefix_content='<!DOCTYPE HTML>\n<html lang="en-US">\n<head>\n<meta charset="UTF-8">\n<title> </title>\n </head>\n<body>\n ';
var sufex_content=' \n</body></html>';
var dynamic_content=String(text_content);
document.write(prefix_content + dynamic_content + sufex_content );
The variable dynamic_content contains the dynamic structure.
The problem is that prefix_content and sufex_content is displayed as html but dynamic_content is written in the page as text. Any one knows why is that or knows how to solve this problem.
Note: when I write the text in dynamic content statically between single quotes it is displayed as html not text.
If you're seeing the content retrieved from your database as plaintext, instead of HTML, its HTML entities are probably getting escaped somewhere along the way. Check the contents of your text_content variable (e.g. use console.log(text_content) and if you're seeing stuff like <div> instead of <div>, go on and find out where your escaping happens and either remove it or manually unescape.
TRY THIS:
var prefix_content='<!DOCTYPE HTML>\n<html lang="en-US">\n<head>\n<meta charset="UTF-8">\n<title> </title>\n </head>\n<body>\n ';
var sufex_content=' \n</body></html>';
var dynamic_content=String(text_content);
var parser = new DOMParser();
var el = parser.parseFromString(dynamic_content, "text/html");
document.write(prefix_content + el + sufex_content );
Or you can try this too: Using jQuery
var dynamic_content=String(text_content);
var el = $.parseHTML( dynamic_content );
document.write(prefix_content + el + sufex_content );
var content = "<div style='color:red;'>TEST</div>";
var prefix ='<!DOCTYPE HTML>\n<html lang="en-US">\n<head>\n<meta charset="UTF-8">\n<title>TEST</title>\n</head>\n<body>\n';
var suffix ='\n</body></html>';
var all = prefix + content + suffix;
var parser = new DOMParser();
var doc = parser.parseFromString(all, "text/html");
console.log(doc.children[0].outerHTML);
Instead of children[0] you can also go for:
doc.documentElement.outerHTML
Results in:
<html lang="en-US"><head>
<meta charset="UTF-8">
<title>TEST</title>
</head>
<body>
<div style="color:red;">TEST</div>
</body></html>
What I am trying to achieve is if a particular page is loaded in the browser for e.g www.domain.com/page then the following piece of code should be added in the page dynamically using JS (similar to how we load the Google Analytics code)
<div id="something">
<img src="http://domain.com/images/someImage.jpg">
</div>
I am trying to figure the script which will load the above mentioned HTML code (anywhere of the page - www.domain.com/page)
Edit 1:
what I am trying to achieve is when the user goes to www.domain.com/page.html I am calling another page lets say page1.html which should contain the script which insert the HTML code I posted above. So I simply want to insert the function which should be enclosed in the tag inside page1.html. Unfortunately I can not edit www.domain.com/page.html
If you want to PLACE that code anywhere in your page using javascript, you first need to identify that PLACE in DOM Using an "id" attribute. Here's an example:
HTML:
<html>
<body>
<div id="target1"></div>
<div id="target2"></div>
</body>
</html>
JS:
var html = '<div id="something"><img src="http://domain.com/images/someImage.jpg"></div>';
document.getElementById('target1').innerHTML = html;
document.getElementById('target2').innerHTML = html;
You can try something like this :
$(document).ready(function () {
var url = window.location.href;
$("#something").append("<img src='"+ url +"' />");
});
$(".documentholder").load("code.html");
If you a specific id of something
$(".documentholder").load("code.html #someid");
If you a specific tag and id of something
$(".documentholder").load("code.html #someid");
Here you are,
just change this part if (getFileName() == "js") with if (getFileName() == "page")
I added js because that is what is returning in the code snippet :)
function getFileName() {
var url = document.location.href;
url = url.substring(0, (url.indexOf("#") == -1) ? url.length : url.indexOf("#"));
url = url.substring(0, (url.indexOf("?") == -1) ? url.length : url.indexOf("?"));
url = url.substring(url.lastIndexOf("/") + 1, url.length);
return url;
}
var div = '<div id="something"><img src="http://domain.com/images/someImage.jpg"></div>';
if (getFileName() == "js") {
$('body').append(div);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
let's say you save this code in a html-file named something.html
$(".documentholder").load("something.html");
in this case the class "documentholder" is the container you put the code in
I have the following tag in HTML:
<div data-dojo-type="dojox.data.XmlStore"
data-dojo-props="url:'http://135.250.70.162:8081/eqmWS/services/eq/Equipment/All/6204/2', label:'text'"
data-dojo-id="bookStore3"></div>
I have the values 6204 and 2 in a couple of global variables in the script section:
<html>
<head>
<script>
...
var newNeId = gup('neId');
var newNeGroupId = gup('neGroupId');
...
</script>
</head>
</html>
Is it possible to have these variables in the div tag in the HTML body? If so, how?
To clarify this a bit more, I need to have the URL in the tag something like this:
url: 'http://135.250.70.162:8081/eqmWS/services/eq/Equipment/All/'+newNeGroupId+'/'+newNeId
I changed it according to your requirement:
<html>
<head>
<script type="text/javascript">
// example data
var newNeId = 10;
var newNeGroupId = 500;
window.onload = function(e){
var myDiv = document.getElementById("myDiv");
myDiv.setAttribute("data-dojo-props", "url:'http://135.250.70.162:8081/eqmWS/services/eq/Equipment/All/" + newNeId + "/" + newNeGroupId + "', label:'text'");
}
</script>
</head>
<body>
<div id="myDiv" data-dojo-type="dojox.data.XmlStore"
data-dojo-props="url:'http://135.250.70.162:8081/eqmWS/services/eq/Equipment/All/6204/2', label:'text'"
data-dojo-id="bookStore3"></div>
</body>
</html>
You could add them to the <div> using the same datalist pattern (MDN docu) as Dojo:
<div id="savebox" data-newNeId="6204" data-newNeGroupId="2"></div>
These attributes are then accessible by the element.dataset.itemName.
var div = document.querySelector( '#savebox' );
// access
console.log( div.dataset.newNeId );
console.log( div.dataset.newNeGroupId );
As #EricFortis pointed out, the question remains, why you want to do this. This only makes sense, if you pass those values on from the server side.
Take one parent div then set its id and then you can rewrite whole div tag with attributes using innerHTML.
document.getElementById('id of parent div').innerHTml="<div data-dojo-type=/"dojox.data.XmlStore/"
data-dojo-props=/"url:'http://135.250.70.162:8081/eqmWS/services/eq/Equipment/All/6204/2', label:'text'/"
data-dojo-id=/"bookStore3/"></div>";
you can append values you wants in innerhtml now.
here's simple native js code to do it
var body = document.getElementsByTagName('body')[0];
var myDiv = document.createElement('div');
myDiv.setAttribute('id', 'myDiv');
var text = 'newNeId: ' + newNeId +
'<br/> newNeGroupId: ' + newNeGroupId';
body.appendChild(myDiv);
document.getElementById('myDiv').innerHTML = text;
