how to trim strings in Javascript with variable lengths? For example:
My Option 1 (+$10.00)
Short Option (+$5.00)
Really long Option
I only want to trim off the (+$10.00) on My Option 1 and the (+$5.00) on Short Option. No trim necessary on Really long Option. When I'm done I want to be left with:
I have this code for HMTL5 Canvas, however this is a JavaScript directed question not a Canvas question.
<script type="text/javascript"> var c=document.getElementById("myCanvas"); var cxt=c.getContext("2d"); cxt.moveTo(0,400); cxt.lineTo(50,a); cxt.lineTo(100,b); cxt.lineTo(150,390); [Code]...
That will draw a line graph, however I want to get the coordinates from a variable in the URL. So it may be example.com/a=500&b=600 . How would I retrieve these two variables and then insert in to they're respective places?
I have variables coming in from JSON files via AJAX calls. Each file will have 3 variables for different background colours. Depending on which button is clicked the background will change colour to the value specified in the JSON file.
I have a dropdown which diplays a companyname with 4 hidden inputs.these hidden input values are set in text boxes on selected indexchange of dropdown.like this
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.
I've been learning javascript for about a week and I'm really struggling right now. This is a homework assignment to help in learning loops and arrays.
What I want to happen is when a form button is hit it will replace the array from the one previous instead of just adding to it. Hopefully that makes sense. What do I need to do? here's my code....
I'm working with SageCRM. When SageCRM outputs the company address, I kid you not, it outputs the value and then a crap ton of HTML non-breaking spaces, a break tag and then repeat for the other address lines.My client added a button to the page via the customization function that links over to MapQuest. But, all those non-breaking spaces mess up the URL.I'm trying to fix it, but I'm having some trouble and thought I'd throw it out to you all.
Code: // Ninja'd this from somewhere to trim whitespace. function trim(stringToTrim) {
I have the following script that converts line breaks from plain text into HTML formatted paragraphs. It takes plain text from one text area field and outputs the new formatted text into another text area field.
function convertText(){ var noBreaks = document.getElementById("oldText").value; noBreaks = noBreaks.replace(/
I have a form in my homepage which takes some values. In that, a text box takes multiple values seperated by spaces. I have allowed only alphanumeric characters in that with the following code.
I am trying to make a simple trim function but this doesnt works. function tr(input){ var i; var str; for(i=0; i<input.length-1; i++){ if(text.charAt(i)==" "){ str+=""+text.charAt(i) } return str }}
Just wanted to share two handy RegEx expressions to strips leading and trailing white-space from a string, and to replace all repeated spaces, newlines and tabs with a single space.
* JavaScript example:
String.prototype.trim = function() { // Strip leading and trailing white-space return this.replace(/^s*|s*$/g, ""); }
String.prototype.normalize_space = function() { // Replace repeated spaces, newlines and tabs with a single space return this.replace(/^s*|s(?=s)|s*$/g, ""); }
" one two three ".trim(); // --> "one two three" " one two three ".normalize_space(); // --> "one two three"
Picture a table where each cell row is 50px tall, with 3 to 5 columns of varying length. For example: thumbnail, name, description, price, options. The thumbnail will always be the same size, but for efficiency of space, nothing else is.
My question is one of overflow. With long descriptions, overflow:hidden will keep things clean. But the most aesthetic presentation would be todynamically truncate the description with ellipses (...) somewhere just before the text runs off the end of the cell (like the ubiquitous [More...] feature, but first filling the cell as much as possible).
This is a typographically desirable feature, and I can come pretty close with php
This does what I want; without the operator 'Number' I get a concatination of the various variables (as expected). Is there some way of globally defining all variables as numbers instead of strings?
ch = wiggy[2]; // ch will contain the character 'C'
however my JS book seems to insist that I do this:
ch = wiggy.charAt(2);
and indeed doesn't appear to mention the first method at all.
Since for my particular purpose I want to treat the string as an array of single characters, I prefer the first method rather than the second. Is there any reason not to pursue this approach?
