I am looking around on the web but I am not finding anything useful. :(
I am having a problem that I don't understand. I am sure that I am doing something wrong, but I don't know well the syntax of jQuery to understand what is that I am not doing right.
I am using animations with JS and CSS 3, and I am having troubles with empty spaces between the words, and to solve this problems I have to find a way to substitute chars inside a string of text with something else. Like an empty space with a , or as a test that I was trying to do a "n" with a "xxxxx".
What I think that I am doing is:
when the page is loaded
Modify the string of any paragraph with the class .fancy-title that contains "n" with a text "xxxxx"
So:
$(document).ready(function(){
for(i=0; i< myLength+1; i++){
var charCheck = $(".fancy-title").text()[i];
if(charCheck == "n"){
charCheck.replace("n", "xxxxxxxx");
}
}
});
But I receive an error that it said:
charCheck.replace("n", "xxxxxxxx"); it is not a function
I am using jquery
and other scripts that are based on jquery to make animations, rotation and scaling... and they are all in the HEAD with jquery first to load.
What am I doing wrong? Manipulation in jQuery does it need a specific .js extension? I understood that was in the basic capability of jQuery, and looking at other examples all creates me the same kind of error.
I even tried
if(charCheck == "n"){
$(".fancy-title").text()[i] == " "
}
But simply the modification it is not applied on the page. I tried with innerHTML as well :(
I feel so incompetent...
Thank you in advance for any help.
$(document).ready(function(){
$(".fancy-title").each(function(i){
var text = $(this).html();
$(this).html(text.replace(/ /g, " "));
})
});
You have no problem with the replace part :).
$(document).ready(function(){
$(".fancy-title").each(function () { //for all the elements with class 'fancy-title'
var s=$(this).text(); //get text
$(this).text(s.replace(/n/g, 'xxxxxxxx')); //set text to the replaced version
});
});
Just a quick example, hope it works.
Have you tried the css style white-space:pre instead of replacing ' ' with ' '?
http://de.selfhtml.org/css/eigenschaften/ausrichtung.htm#white_space
It seems you are trying to replace a single character with a new string.
You might be able to get the right result by dropping the iteration and simply call .replace on the jQuery-object.

I am having a problem I want to attach the registered trademark symbol a button and I want it to be done with jquery because there are lots and lots of buttons that require the sign when I used it with html for example(below) it worked.
<input type="button" class="button_a" value="Value ®" />
But when I used jquery as below it returns as plain text:
$('.button_a').each(function(){
$(this).attr("value",$(this).attr("value")+" ®");
});
I don't want to waste my time and space by putting ® in all the button's values so I want it to be done in jquery but what am I doing incorrect.
I know it's a sluggish question but please someone help out me in this question
Javascript may be also used.
For more info please comment and ask
Thanks....
® is being rendered as a text string, but you can use unicode \u00AE
$('.button_a').each(function(){
this.value = this.value +" \u00AE";
});
http://jsfiddle.net/fbuohvm1/
or just ®:
$('.button_a').each(function(){
this.value = this.value +" ®";
});
http://jsfiddle.net/fbuohvm1/1/
Because, while the DOM you are manipulating was initialised from an HTML document, you are now dealing with DOM and not HTML. You are writing the value as text not as HTML.
You need to use either a literal character ("®") or a JavaScript escape sequence ("\u00AE").
You have to encode it first before setting the value of textbox.
$('.button_a').each(function () {
$(this).val("value " + $("<div/>").html('®').text());
});
$("<div/>").html('®').text() will return the encoded value.
Demo: https://jsfiddle.net/tusharj/t2gwptys/
you need to process content by html(), because html entities is manipulate by html() function, try this code.
$('.button_a').each(function(){
$(this).val($("<p/>").html($(this).val()+" ®").html());
});
Use a hidden div.
$('.button_a').each(function(){
var decoded = $('<div/>').html('®').text();
$(this).val($(this).val() + ' ' + decoded);
});
See Sample
In your case plain js is more straightforward:
$('.button_a').each(function(){
this.value += " ®";
});
-- EDIT --
Unfortunately this is still escaped, in fact you need
this.value += " \u00AE";
This is similar to other questions, but it's about something specific.
The first example doesn't do anything (breaks)
The second example works except that it hacks up html tags (specifically a tags) as well, so href="something with numbers" get hashed and then the whole thing falls apart
Then I get anchors that have their href attributes hashed up with span tags. Obviously that isn't what I want. What am I doing wrong? There must be some way to put all numbers and ", - : ()" inside a span without hashing up the html tags themselves.
$('#main-content p').contents().not("a").html(function(i, v) {
return v.replace( /([0-9(),-:]+)/g , '<span class="number">$1</span>');
});
$('#main-content p').html(function(i, v) {
return v.replace( /([0-9(),-:]+)/g , '<span class="number">$1</span>');
});
You are replacing all number. You need to only select the text nodes within the element. This code is not tested, but should work.
EDIT: You have to also call .contents(). See this answer
EDIT 2: I got it working in this FIDDLE. Let me know what you think. Did you mean to replace special characters as well as numbers?....because that is what is currently happening per your original regEx.
$('p').contents().filter(function () { return this.nodeType === 3; }).each(function(){
$(this).replaceWith($(this).text().replace( /([0-9(),-:]+)/g ,
'<span class="number">$1</span>'));
});
I am close to getting this function working, but not quite there yet.
The basic logic says find any p element that contains "+", strip the "+" from the text and try and replace the existing content with the new content and add a class.
Initially I had all of the matched elements being returned and concatenated into a single paragraph. So I tried to create an each function. I am now seeing the right results in the console, but I am not sure how to replace the content for the matched paragraph only (using $(this)).
I've made a fiddle here: http://jsfiddle.net/lharby/x4NRv/
Code below:
// remove bespoke text and add class
$qmarkText = $('.post p:contains("+")').each(function() {
$qStr = $(this).text().slice(1);
$qmarkText.replaceWith('<p class="subhead-tumblr"' + $qStr + '</p>');
console.log($qStr);
});
I know that $qmarkText is not quite but not sure how to fix this, have tried several variations.
Hopefully someone can help me out.
You could use following snippet:
// remove bespoke text and add class
$qmarkText = $('p').filter(function () {
return $(this).text().substring(0, 1) === "+"
}).each(function () {
$qStr = $(this).text().slice(1);
$(this).replaceWith('<p class="subhead-tumblr">' + $qStr + '</p>');
});
DEMO
This avoid using :contains() which will match even character '+' is inside content text, not only at the beginning.
I have a html code inside string
string_eng += '<b>Year Bonus</b> - bonus for each year</br></br>';
And I want to put this inside textarea, but when I do it, the result is:
- bonus for each year
It simply deletes all things inside the html tags. I just want to show all the code inside the string. I already tried <xmp>,<pre>, but none of them worked.
Thanks for any help.
EDIT.
Code with which I input data from the array to the textarea/code.
$('body').append('<code class="code_text"></code>');
for(var i=0; i<tag_list.length; i++){
var string='';
string+='---------------------------------------------------------------------------------\n';
string+='tag: '+tag_list[i][0]+'\n';
string+='nazwa_pl '+tag_list[i][1]+'\n';
string+='nazwa_eng '+tag_list[i][2]+'\n';
string+='tekst_pl '+tag_list[i][3]+'\n';
string+='tekst_eng '+tag_list[i][4]+'\n';
string+='\n\n\n';
$('.code_text').append(string);
}
I tried this using jsfiddle:
HTML
<textarea id="code"></textarea>
JavaScript
$(document).ready(function() {
var string_eng = '';
string_eng += '<b>Year Bonus</b> - bonus for each year</br></br>';
$("#code").html(string_eng);
});
Output (contained in textarea)
<b>Year Bonus</b> - bonus for each year</br></br>
Try it here: http://jsfiddle.net/UH53y/
It does not omit values held within tags, however if you were expecting the <b></b> tags to render as bold within the textarea, or the <br /> tags to render as line breaks, this wont happen either. textarea does not support formatting.
See this question for more information: HTML : How to retain formatting in textarea?
It's because you're using the jQuery .append method which seems to parse the string and insert it afterwards. I don't know jQuery at all, so there might be another special jQuery method, but here is a simple fix:
$('.code_text').append(document.createTextNode(string));
Edit:
I just read and tried the answer of Salman A. The "special jQuery method" exists and he used it. You can use this:
$('.code_text').text(string);
I thought this one would be easy, but after an hour of googling, i still haven't found anything.
I know how to update content in a div with jquery:
$(".div").html("stuff");
but that replaces the current content in the DIV (over writes it). I need the current content to remain there.
I don't mind if you know a way in Javascript or Jquery.
Thanks
You can either use append(), prepend() or html()'s inbuilt function:
$('div').html(
function(index,oldhtml){
var newString = 'something';
$(this).html(newString + ' ' + oldhtml);
});
JS Fiddle demo.
References:
append().
html().
prepend().
I think you're looking for .append()
Concat?
var old_content = $(".div").html();
$(".div").html(old_content + "newstuff");
