I have a Chrome extension in which I'm fetching tab title and url, and putting them into one single line. Same as Chrome History. I want to separate them visually, dark title, lighter url.
and for that I'm using this code
nodeTitle.innerHTML = tabs[j].title + "<span id='url'>" + ' - ' + tabs[j].url + "</span>" ;
CSS for #url is set and everything works fine, unless page title have some actual HTML code/tag in it, and title get messed (ofc. innerHTML works as it supposed to).
example page...look at title
innerText doesn't help in this situation, because I need < span > treated as it is.
Is there any way to cancel HTML execution for that first part (which can be any variable) or I have to separate them into two different elements and style them?
(and I'm really trying to avoid that)
...maybe check for tags and insert space if any exist??!... relized while writing this question, span tag in pointy brackets :)
You can use createTextNode as an easy (though perhaps not very efficient) way to do this:
function textToHtml(str) {
return document.createTextNode(str).innerHTML;
}
nodeTitle.innerHTML = textToHtml(tabs[j].title) + "<span id='url'>" + ' - ' + textToHtml(tabs[j].url) + "</span>" ;

I'm working on an add-on based in the CardService functions in Google Apps Script. At one point in my UI, I want to have a pair of hyperlinks in the same "row" of the card (the first being left-aligned on the card, and the second being right-aligned).
Here's what I have so far:
var urlText = CardService.newTextParagraph()
.setText("<a href ='" + shURL + "'>" + "File No. " + fileNo + "</a> <a href ='" + folderURL + "'>" + "Drive Folder</a>")
Obviously the manual way is the wrong way to space the two out.
What do you think is the best way to do this? I see the Grid widget, but it doesn't seem to enable me to have separate hyperlinks. Same with the DecoratedText widget.
Any ideas would be much appreciated. Thanks!
Summing up what's discussed in the comments, at the date of this answer textParagraph() provides Text Formatting support but limited to:
Bold = <b>test</b>
Italics = <i>test</i>
Underline = <u>test</u>
Strikethrough = <s>test</s>
Font color = <font color="#ea9999">test</font>
Hyperlink = google
Time = <time>2020-02-16 15:00</time>
Newline = test <br> test
Aside from the above, text alignment is not mentioned.
After testing Grid and DecoratedText options are also not suitable for this use case either. Also, be aware of the use of HTML/CSS for its format falls in one of the restrictions documented here.
Since this is a missing feature, you may want to submit a Feature Request so it may be considered in the future.
I am trying to use a php script to generate HTML in order to save lines and what not. I am using jQuery to call my php and then put the result into a specified div as shown below:
function createSidebarRow(div, cellNum, rowName, rowDesc) {
$("#" + div).load("createIndexSidebarRow.php?cellNum=" + cellNum + "&rowName=" + rowName + "&rowDesc=" + rowDesc);
}
However, when this is executed the HTML is not updated on the page, I can see that the code has worked because the browser network activity confirms it. I am trying to figure out what is causing it to not update.
This is the network activity confirming the echo'd HTML.
Sorry for stating the obvious, but the div you are trying to fill up does exist with that particular id right?
If so, try this:
$("#" + div).load("createIndexSidebarRow.php?cellNum=" + cellNum + "&rowName=" + rowName + "&rowDesc=" + rowDesc, function() {
alert('success');
});
If the id does exist (and it's unique) and you get an alert there should be no reason for it not to work.
It might be so, that the div is not yet created in the DOM. (the div that should received the html).
Are you calling createSidebarRow directly on page load?
If so, put the function call in a document ready:
jQuery(document).ready(function(){
createSidebarRow (... );
});
Turns out jQuery doesn't play ball when you include spaces in the POST URL. I removed the space and used %20 instead and all is well now. Thanks for any advice.
I want to add a linebreak in Javascript, but \n is not working and nothing else I found so far is not working (like <br> or \n). Also, because of the programming I cannot use .appendChild.
for (i=getchilds();i<number;i++){
container.appendChild(document.createTextNode("\n" + "Pers. " + (i+1) + " \u00a0"));
var input = document.createElement("input");
input.type = "number";
container.appendChild(input);
}
I think you may be confusing whitespace with the representation of whitespace. In your case you're appending characters that represent white-space to a string that you intend to be displayed as a line-break. I assume you're then appending it to an element whose style is not set to display it as white-space.
There are four basic ways to fix this:
Use an ordered list. If you can, do this, since it will be both structural and semantic. Notice the link shows how to control the list-item text (controlling the start number is more challenging).
If the container-referenced element accommodates this, add white-space: pre to it's style. This will cause your line-breaks to come into view. It's best to do this with CSS, but you can do it with Javascript too.
Replace the \n with a <br>. Denys Séguret has an example of this.
Use a pre tag for the container-referenced element. <pre> automatically respects and displays line-breaks in content. This of course implies your content accommodates using a pre-formatted tag.
Change your code to insert into a textarea or a set of pre tags.
You might see your code injecting a single space in place of the line breaks in a plain text input of your browser is Firefox chrome or opera.
You can't insert \n in text node and have them correctly rendered in an element with standard white-space rendering.
Two solutions here:
insert <br> elements
container.appendChild(document.createElement("BR"));
container.appendChild(document.createTextNode("Pers. " + (i+1) + " \u00a0"));
use innerText in SPAN
var node = document.createElement("SPAN");
node.innerText = "\n Pers. " + (i+1) + " \u00a0";
container.appendChild(node);
The first one is the most relevant in your case, but the fact innerText doesn't remove newlines (contrary to textContent) is often useful.
I'm just learning JavaScript, and I've come up with the following page that "draws" a guitar fretboard by creating a 6X16 grid of images (the first column is the set of "open notes" on the very left hand side of the image grid). The page is here.
Each of the six rows represents a string on the guitar so, six strings, six rows. But what I can't figure out is how to make the rows butt up right next to each other, with no whitespace between the top of one row and the bottom of the next. So, what I get is this:
But what I want is this:
The way that the JavaScript works is to run through a loop that is 16 items long - one "open string" image, and 15 "fretted note" images, and at the end of the loop it generates a <br/>tag. These strings are inserted into an InnerHTML value of a <p> element, and the grid of images gets drawn. Here is the line of code that generates, as an example, the fretted note image:
for(frets=0; frets < 17; frets++){
GuitarNeckImg.innerHTML = GuitarNeckImg.innerHTML + "<img title=" + allNotes[frets + 1] + " src=images\\" + allFretImages[frets + 1] + ">";
continue;
}
What I don't understand is:
What CSS attribute/value pairs do I need to enter to get the images
to not have any space between them above and below,and
How do I write the JavaScript code to add those CSS attribute/value pairs to the tag in my code?
Add'l information:
I have tried, as an example, to write the following code in my JS file:
GuitarNeckImg.innerHTML = GuitarNeckImg.innerHTML + "<img title=" + allNotes[frets + 1] + " style=padding:0px; margin:0px;" + " src=images\\" + allFretImages[frets + 1] + ">";
But this produces the following HTML output:
<img title="F.Esharp.Gbb" style="padding: 0px;" src="images\F.jpg" margin:0px;="">
So the first problem is specifically around JS syntax and how I need to craft the code statement to generate multiple attribute/value pairs for the style tag, and the second is which CSS tags I should use to get my desired results.
Thanks in advance, and please feel free to let me know what additional information I can provide.
An appropriate line-height value, such as 0.70, should do exactly what you want.
Try this...
//We define the text variable that needs to be cleansed of line breaks.
Var someText = "Here's some text.\n It has some line breaks that will be removed \r using Javascript.\r\n";
//This javascript code removes all 3 types of line breaks
someText = someText.replace(/(\r\n|\n|\r)/gm,"");
Best of luck...
I'm working on adding page title notifications for an install of AJAXchat. I'm using a jQuery plugin called jquery-titlealerts to achieve this. If I assign the method on the onclick event it works as correctly and changes the page title. But that doesn't work as I need. I need it to change the page title each time a new div is created. Here is the js that dynamically creates a new div every time someone submits a message:
return '<div id="'
+ this.getMessageDocumentID(messageID)
+ '" class="'
+ rowClass
+ '">'
+ this.getDeletionLink(messageID, userID, userRole, channelID)
+ dateTime
+ '<span class="'
+ userClass
+ '"'
+ this.getChatListUserNameTitle(userID, userName, userRole, ip)
+ ' dir="'
+ this.baseDirection
+ '" onclick="$.titleAlert(\'Error!\');">'
+ userName
+ '</span>'
+ colon
+ this.replaceText(messageText)
+ '</div><script>$.titleAlert(\'Error!\');</script>';
return
As you can see I've tried creating a <script> block to load just below the div - and it does but for some reason isn't changing the document title. If you click on a message generated in the chat it will work though because it is being fired from the onclick event..
I'm not sure what else to try to get it to work when each div is loaded.
In the place where you're calling the function that has this return statement, after you call that function you should update the page title. If you don't want to do it that way, you can have the function that returns your new Div content update the page title right before it returns.
Alternatively, consider using jQuery's $.ajax() method with a complete (or success) callback to do the title modification. Honestly, this would be my preferred approach if I were to be given this problem to solve.
You can read all about $.ajax() here.
Inserting a script block programmatically almost never works in modern browsers for obvious security reasons.
Instead, make the script that receives this HTML do the alerting, possibly based on part of the content of the HTML; say, a hidden span containing the message to pull out and use as the title.
