The Question and Codes
I am struggling with the below code:
$('.rdsubs-mysubscriptions table tbody tr td a').each(function() {
var subItem = $(this).html();
//console.log(subItem);
var subItemStripped = subItem.substring(12);
console.log(subItemStripped);
$('body').find('span:contains("subItemStripped")').addClass('HELLO');
}); // end of each function
When I check the console for subItemStripped then it shows this:
Framework
Content
Slideshow
Which means (in my head at least ;-)) that for each span that is inside the body it should find one of these subItemStripped and where it finds a match it should add the class hello but this is not happening.
Actually, nothing is happening.
When I change this line:
$('body').find('span:contains("subItemStripped")').addClass('HELLO');
to
$('body').find('span:contains("Framework")').addClass('HELLO');
It works nicely. So am I putting the variable subItemStripped wrongly in there or has it something to do with the .each() function.
I tried the below things to make it work
With the above code I tried a couple of variations before I came here:
$('body').find('span:contains(subItemStripped)').addClass('HELLO');
$('body').find("span:contains('subItemStripped')").addClass('HELLO');
I also tried it with completely different sets of code I gathered from other SO posts but none of those worked. Why I don't know.
$("span").filter(function() {
return $(this).text() === subItemStripped;
}).addClass("hello");
$("span").filter(function() {
return $(this).text() === subItemStripped;
}).css("font-size", "6px");
Why do I need this
I know I don't have to explain why I need this but it could be useful in coming up with other great ideas if the above is not feasible.
I have a webpage and on that page is a menu filled with products that a user can download if he/she has access.
Each menu item has a span with the title in it. Those titles are built up like: Framework Content Slideshow
On this same page is also a component that shows all the users subscriptions.
With the above code, I look to all the subscriptions of the user. Which returns
CompanyName Framework CompanyName Content CompanyName Slideshow
Then I Strip .substring(12) all the parts that I know are not present inside the menu. Which leaves me with Framework Content Slideshow
At this point, I know that some menu titles and the stripped item are the same and for every match, I want to add a class upon which I can then add some CSS or whatnot.
Hopefully, the question is clear and thanks to everyone in advance for helping me out.
#gaetanoM You are completely right. Right after I posted the question I came on this site:
jQuery contains() with a variable syntax
And found the answer which is the same as you are saying!
$('body').find("span:contains('" + subItemStripped + "')").addClass('HELLO');
Thanks so much!
#gaetanoM Can you make your comment in an answer? Then I can select it as the accepted answer. I am answering this question now just to make sure it has an answer. As people get punished for asking questions that don't get answers.
How does one insert, or better, replace the current selection with some content and then select it?
Here's my text: Hello nice world!
As you can see nice is selected by the user. Now he clicks a button and this code is run:
editor.execCommand('mceReplaceContent', 'nasty');
This works just fine, the result is: Hello nasty world, but nothing is selected.
How do I make it automatically select nasty in the result content?
This seems like a very natural thing for one to want to do, but can't seem to find a straight-forward solution. I need this to work in mostly two cases 1) I am wrapping the selected text in a f.e. span element or 2) I am removing the wrapping span element.
I know there are better ways of dealing with nodes, but I'm more concerned about the pure text scenario right now.
Thanks in advance!
P.S. I am using TinyMCE 3 not 4.
I found this in the docs (API 3.x)
// Sets some contents to the current selection in the editor
tinyMCE.activeEditor.selection.setContent('Some contents');
// Selects the first paragraph found
tinyMCE.activeEditor.selection.select(tinyMCE.activeEditor.dom.select('p')[0]);
The setContent function does practically the same as execCommand('mceReplaceContent'). I did not found something like the easy DOM properties selectionStart & selectionEnd.
I'm trying to align the text in the menu at:
http://crango.uofydating.com/dir/New2.html
In the 1st tab, I want there to be a line break after "Item".
In the 2nd and 3rd tab, I want there to be a line break after "This is".
I only posted the part of the menu that I need help with, so it may look a bit odd. But it is connected to some Javascript code which makes it more challenging to edit. The JS can't be removed.
Here is your solution
I have created a fiddle for you
Use .html() instead of .text()
CODE:
.html('<strong>' + $(this).find('a').html() + '</strong>')
It works great ;)
Check it
Fiddle http://jsfiddle.net/krunalp1993/yL6Tn/1/
Hope this helps you :)
In your js code, you are setting back to your original text inside strong tags with .html inside the .click method. So just insert the line break in there.
Insert break in this line in your js:
.html('<strong>' + $(this).text() + '</strong>')
I've been stuck on this for hours and would love some help. I'm using tinyMCE with the syntaxhl plugin using syntaxhighlighter 2.1.382.
Everything works great with non-highlighted code. However, when using setContent with highlighted code, I get no joy. I'm hoping there is something obvious here I'm not seeing.
$(window).load(function() {
tinyMCE.activeEditor.setContent('<p>here is some code:</p>
<pre class="brush: jscript;fontsize: 100; first-line: 1; ">var fs = require("fs");
module.exports = function(app, service){
fs.readdir(__dirname + "/controllers", function(err, files){
if (err) throw err;
files.forEach(function(file){
var name = file.replace(".js", "");
require("./controllers/" + name)(app, service);
});
});
};</pre>');
});
However, this doesn't work. I've tried to debug the javascript, but I'm having trouble there to (at least with the chrome dev tools).
There is no error message, just no populated content. I've tried using {format: 'raw'} as suggested in the tinyMCE docs, but no luck there.
I'm hoping somebody else has tried to do this and succeeded.
I do not know the highlight plugin, but i guess it inserts a special stylesheet into the editor iframes head. This leads to the styling (highlighting) of special html tags a.s.o..
In this case the content is not affected/changed.
You won't be able to get your highlighted content as it looks with this plugin.
Unfortunately, I never got the above code to work. I think that the <pre> tag must take over in the browser and mess things up. Also, I'm a bit dubious still of the line breaks causing harm. #Thariama was some help which was great, however, after reading all the documentation on extended_valid_elements, valid_elements, and valid_children, and configuring the tinyMCE init many ways, I couldn't get this to work.
However, I did find a solution for me. It turns out if I set the <textarea> directly with encoded html (so <pre> tag becomes <pre class="brush: bash;fontsize: 100; first-line: 1; ">) then it works properly. Since this is working and it cuts out having to do a setContent after tinyMCE is initialized, this will work for me.
The syntax highlighting is working nicely. I came across this link while searching around if anyone else wants to do the same.
Initially I asked this Question and written my own plugin to achieve the same,But i am facing very strange issue regarding to css of table.
After applying the plugin table cells borders are getting dis-sorted.
jsFiddle of the problem: Problem demo
In fiddle you can see that after first cell of the first tr, the header border line and table border line don't line up. I want the border line of thead cells and td cells to line up.
Can anyone tell me how to achieve that?
Lets start by doing a bit of a clean up of the code you posted so I can actually read your code and maintain a firm grasp on reality while we go down this rabbit hole.
If you write clean code, your problems will be exceptionally easier to see.
So lets clean it up and watch as all the problems here reveal themselves.
Step one: Your jsFiddle sets it to run "onDomReady," which basically means you've got $(document).ready(...) calling all the code in the box, which is fine, except you're got another got $(document).ready(...) inside there. Lets change that.
Step two: Lets add some white space and proper indentation in there, and stop using these one letter variable names.
{} are scope brackets, they should indent, not cover everything, they let us know what part of scope something is in.
Don't write .each() loops on one line, this adds no value and makes your code confusing to read.
$t should be called something meaningful, lets try element, because it holds the $(this) element, which is the active element you're working with.
w should be called something meaningful, but since you only use it twice I'm just going with element.width().
o needs to be less ambiguious, lets go with obj.
Step three: Selection structures
if(typeof(i)=='number')o.height=i;
else if(typeof(i)=='object')o=i;
else if(typeof(i)=='undefined')o={height:300}
Break that up, make it readable. Saving lines doesn't make you a better program, writing clean and easily understandable code will.
Why not use the switch-case statement?
switch (typeof(i)){
case "number":
o.height=i;
break;
case "object":
o=i;
break;
case "undefined":
o={height:300};
break;
}
Step four: Don't in-line styles. Just don't. There's no reason to do it, and it makes everyone's life harder.
Instead, lets just place the styles gently into the style sheet where it belongs, and make the parent=$('...') line look like parent=$('<div><div></div></div>').appendTo('body');.
Step five: Closure doesn't pass any value to arguments
After a bit of clean up, we see this block of code:
self.width(self.width() -
function(width){
var parent,child;
if(width===undefined){
parent=$('<div><div></div></div>').appendTo('body');
child=parent.children();
width= (child.innerWidth()) - (child.height(99).innerWidth());
parent.remove();
}
return width;
}()
);
Okay, that's a problem. Lets cut out a few lines to point out the problem here:
self.width(
self.width() -
function(width){
/*...*/
if(width===undefined){
/*...*/
}
return width;
}()
);
So, a quick refresher on this pattern you have here:
(function(arg1){
/*code*/
})(data);
Data gets passed to arg1. Arg1 declaires a variable in the scope local to that function, it doesn't get anything from outside. Outside data is passed in through the set of () that call the function, which your code had left abandoned. Think of it this way:
var msg = function(text) {
alert(text);
};
Then you call it as...
msg("hello world");
What your closure is doing is almost the same thing, except where you define your function, you also call it. Thus...
(function(text) {
alert(text);
})("hello world");
So, you need to pass a value of some sort into there, other wise this whole thing is always undefined. Lets do that. What are we passing? I have no way to be sure. This is why programmers need to add comments to their code.
Step six: Comment your code so people other than yourself will look at this code and have not a damn clue what you truthfuly wanted to do, and can only guess. It's like you posted a 200 point bounty and didn't bother helping people who want to help you. Why are you doing this to yourself, dude? Why couldn't you just go //This is what this does to give me a hint? What did I ever do to you?
Step Seven: Lets see if we can make the JS changes work with the JS Fiddle
Great odin... that HTML's 2000 lines long?
Okay, I'm working with pastebin here for the sake of saving space in the post here.
Alright, you started off with this: http://pastebin.com/xjmm4cev
You're using a lot of no-wrap, and putting classes onto individual elements. You shouldn't have to do this on each HTML element, CSS takes care of that very effectively, so lets go ahead and just rip out all the nowrap=nowrap and class="header" stuff (we'll put it back in a moment, but only ONE per group, not each element).
Then lets get rid of the useless blank lines.
Lets run this through HTML tidy and get it nice and indented correctly.
http://pastebin.com/uHtSZ4h5
Much easier to read over. Okay, so what do we see here? Well, it looks like you keep going in circles, cutting and pasting the same thing again and again. You also in-line javascript such as using onchange and onclick attributes. This is generally an awful thing to do to your code, and makes it hard to maintain (as I'm sure you've seen with this 2000+ line beast of cut+paste 27 times in a row).
So, lets take a look here:
elements, not inside a form
Elements in a table that are outside of rows, but not head/body/footer sections of a table
Code that's a huge pain to maintain because it keep going in circles, if you need to change this, you're basically screwed.
Lets fix all that.
We're going to use events in the tags, rather than in-line things. So, all of those in-line onchange and click attributes get the boot.
All of these inputs that are just floating around need to get put into a form, and taken out of this place in tables that only rows or table sections belong in.
Figure out how we can not have excessive input elements, if we can help it.
What the heck is the )="" that you have on every input button? Deleted.
So, here's all of your hidden boxes: http://pastebin.com/LXZSkvyf which I've removed, because we don't have a anywhere.
And here's what the code looks like without all of these weird things in it: http://pastebin.com/MiaJTGpb
Much more readable, but still not quite there.
Step 8: What can you do to make the HTML of the table work better?
You're using Thead and Tbody, and that's good.
You're using attributes for things like cellpadding, that's bad.
You've given each body row an ID. I don't feel you needed to do this, but it's not always bad. However, I'll show you how you could work without it.
You give some selects a select-box class, but it's nowhere in the css. I've removed it.
You give a title attribute to the selects that says "option_value". The title attribute is generally used to make a tool-tip popup when you leave the mouse over something. I'm not sure what you're going to do here, but that's bound to confuse your user. I'd highly suggest giving something better than option_value in that place.
You keep using the ID Submit_FMS_AddDelivery. HTML ID tags are meant to be unique, and used only once on one element. You've got it 27 times, that's bad. I don't think you need an ID on it, so I've removed it.
You've also got input-btn going on, I'm removing it, because you haven't shown it's used anywhere.
You probably don't need any of these ID tags on select and TR to be honest, so I'm pulling them.
What's that look like? Basically, you've got what's almost just the data, in it's nice pure form. That's good. http://pastebin.com/UNS6CAtb
Step 9: What were you trying to do?
Lets step back and take a look here.
All you really wanted to do was keep a fixed header, but you've ended up doing a lot of JavaScript hacks and manipulating the DOM in a lot of places. We need to stop doing this. Is there a simpler way to do what you want?
I'll have to expand on how to make this function with the rest of your stuff, but I get up for work in a few hours. I'll update again with more... But we'll get there.
Right now, because I haven't fixed what I took out, it doesn't look right. But I'm tired.
So, here's where we are so far: http://jsfiddle.net/5C6z7/
Plus those inputs we took out (and will be going back in later, in a different way)
Looks like all you have to do is to take the padding into account: each cell has 3 px padding both left and righ so you have to add 6 px to the width:
$t.find('tr:first th').each(function(){cols.push($(this).width()+6);});
Otherwise the cells with only one word inside will "push" the actual width a bit wider so that the word will fit and other cells with space to move will compensate by becoming a bit narrower. The header and the body both do this independently with different contents which creates the difference in actual cell widths.
EDIT: For Firefox you also need to widen the table so that the cells fit. After calculating the column widths add
var actualWidth = $t.width()+cols.length*6;
$t.width( actualWidth );
And later change the wrapper to:
$wrap.css({width:actualWidth,height:o.height,overflow:'auto'});
EDIT 2: To have both the header and the body scroll simultaneously you need to wrap them both to an outer div that handles the scrolling.
var $outerWrap = $( '<div>' ).css( {width:"300px", overflow:'auto' } );
var $wrap=$('<div>').css(
{ width:actualWidth,height:o.height,"overflow-y":'auto', "overflow-x":'hidden' }
);
$firstRow.wrap( $outerWrap );
$firstRow.after( $wrap );
$wrap.append( $t );
Demo: http://jsfiddle.net/YcRTz/2/
What about replacing '<th>' tags with '<td>' tags?
No extra js code required.
http://jsfiddle.net/spQAh/7/
Okay so instead of troubleshooting or using anything complex, I came up with simple CSS + JS solution to your problem. Take a look at http://jsfiddle.net/TdLQT/
Obviously, the process of making header static, can be made dynamic, meaning trigger it after user scrolls a bit or have it there by default or count other object's position from top window and trigger static behavior when it reaches or exceeds certain pixels. I can provide that if you give me details on exact design of your HTML page.
Anyways, I as you can see, have used fixed pixel heights which you can choose not to or make them elastic or dynamic. What is important to know is that, though solution relies on JS a bit, output position is purely from CSS. I am using classes to manipulate the position.
the simple solution is that when you calculate the width of the column you do not include padding. So you need to change the line
$t.find('tr:first th').each( function() {
cols.push($(this).width());
});
to
$t.find('tr:first th').each( function() {
cols.push($(this).outerWidth());
});
if your cells have margins use .outerWidth(true)
This works in quirks mode with IE7&8 and Chrome IE8 has a problem in strict mode. However I believe that that problem is caused by the added scrollbar. If you want to use IE8 in strict mode you have to allow for the width of the vertical scrollbar..
