JavaScript - Strokestyle Changes Prior Lines
I'm making a graph in Canvas. I plot the grid with ctx.strokeStyle = '#ccc';
I then plot the data lines with ctx.strokeStyle = '#000';, and the GRID color then turns back to '#000' too! The same happens with any color. The same happens with lineWidth. The fillStyle of the labels is not affected. It happens even if I surround the code with save/restore. It happens in both Firefox and Chrome. Has anyone else had this problem? Is there any way around it? Similar TutorialsHi Guys, I have an situation. An DIV has two sections, one to prompt user info and other displays ads. While the ads section is in an iframe(inside DIV) whose src is set dynamically, i.e. when user tries to close the browser, then my code brings up the DIV and sets the src of that iframe also an browsers default prompt stays on top of the page asking for 'Ok' and 'Cancel' button to leave/stay on the page respectively. My problem is that the iframe is not loaded unless user clicks on the 'Cancel' button. This happens in IE,Chrome and Safari but works fine in Firefox. I know this is an browser's behavior but still expect an cross browser solution. Can a random page be loaded without a prior visit to a site? I have a list of 15 people with a photo and contact information in a table with 3 columns and 5 rows. The issue is that the people near the bottom want a chance to be at the top the first time the page is viewed. It is unlikely that a second visit would happen. Is this possible to load a random page for a site without it being viewed or logged into before, therefore no cookies will be used. My knowledge of Java script code is limited so any help would be great. Thanks Motty Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hello every body i have a problem with javascript i wrote a script which process the entry of a text area 1 and i made the script process only the first line of the entry i want a method to make the script to process all of the lines which the user enter it OR make a varibals to every line entered from the user i am so sorry about the weak language thank you in advance i have a program which gets values from different arrays and displays them on screen. how do i insert a break every 5 lines so its easier to read?
Here I have a code to redirect a page to one of these three pages. But is there a limit to the amount of websites I can add? Code: <script type="text/javascript"> var urls = new Array(); urls[0] = "http://www.google.com"; urls[1] = "http://www.youtube.com"; urls[2] = "http://www.codingforums.com"; var random = Math.floor(Math.random()*urls.length); window.location = urls[random]; </script> Would I be allowed to have, say, hundreds of thousands of different sites? Or would the script stop working? Thanks. I am new to javascript but am proficient in .net languages. If I have a text file that is structured as follows; -35.889,150.984 -35.578,151.022 -35.449,150.993 I have two questions; 1. How can I read the text in that file into an array? I've tried Code: var file = "X:\ASP.Net\GoogleMaps\GMAP\MarkerCoordinates.txt"; //file:\\X:\ASP.Net\GoogleMaps\GMAP\MarkerCoordinates.txt $.get(file,function(txt) P.S. I tried the commented way above also and that didnt work I also tried using XMLHttprequest like so Code: var txtFile = new XMLHttpRequest();
txtFile.open("GET", "file:\\C:Gmap\test.txt", true);
2. How do you iterate through each line in the array? I'm not sure how to do a for-each in javascript, would be simple in .net Thank you, in advance, for any assistance Hi guys. I'm using a jquery plugin called innerfade, which I got from he http://medienfreunde.com/lab/innerfade/ . I've used it to fade few lines of text into each other: Code: <div class="fade"> <p>Line 1 asdfghjkl</p> <p>Line 2 sdasdsafasdgedgr</p> <p>Line 3 ddddddddddddddddddddd</p> </div> So only first line appears on page load, then after few seconds fades into Line 2 etc. Everything works perfect, but there is only one problem - the text is not centered even if it says so in CSS. Since the lines have different lenghts, the shorter the line the more it's aligned to the left. I've added properties for both div and p's - tried all combinations of text-align: center and margin left & right: auto. No joy. But when I remove the script all 3 lines appear centered perfectly. So my question is how do I make them centered? I presume it has to be added in the JS part since it seems to be overriding the CSS. Here is the script's full code: Code: (function($) {
$.fn.innerfade = function(options) {
return this.each(function() {
$.innerfade(this, options);
});
};
$.innerfade = function(container, options) {
var settings = {
'animationtype': 'fade',
'speed': 'normal',
'type': 'sequence',
'timeout': 2000,
'containerheight': 'auto',
'runningclass': 'innerfade',
'children': null
};
if (options)
$.extend(settings, options);
if (settings.children === null)
var elements = $(container).children();
else
var elements = $(container).children(settings.children);
if (elements.length > 1) {
$(container).css('position', 'relative').css('height', settings.containerheight).addClass(settings.runningclass);
for (var i = 0; i < elements.length; i++) {
$(elements[i]).css('z-index', String(elements.length-i)).css('position', 'absolute').hide();
};
if (settings.type == "sequence") {
setTimeout(function() {
$.innerfade.next(elements, settings, 1, 0);
}, settings.timeout);
$(elements[0]).show();
} else if (settings.type == "random") {
var last = Math.floor ( Math.random () * ( elements.length ) );
setTimeout(function() {
do {
current = Math.floor ( Math.random ( ) * ( elements.length ) );
} while (last == current );
$.innerfade.next(elements, settings, current, last);
}, settings.timeout);
$(elements[last]).show();
} else if ( settings.type == 'random_start' ) {
settings.type = 'sequence';
var current = Math.floor ( Math.random () * ( elements.length ) );
setTimeout(function(){
$.innerfade.next(elements, settings, (current + 1) % elements.length, current);
}, settings.timeout);
$(elements[current]).show();
} else {
alert('Innerfade-Type must either be \'sequence\', \'random\' or \'random_start\'');
}
}
};
$.innerfade.next = function(elements, settings, current, last) {
if (settings.animationtype == 'slide') {
$(elements[last]).slideUp(settings.speed);
$(elements[current]).slideDown(settings.speed);
} else if (settings.animationtype == 'fade') {
$(elements[last]).fadeOut(settings.speed);
$(elements[current]).fadeIn(settings.speed, function() {
removeFilter($(this)[0]);
});
} else
alert('Innerfade-animationtype must either be \'slide\' or \'fade\'');
if (settings.type == "sequence") {
if ((current + 1) < elements.length) {
current = current + 1;
last = current - 1;
} else {
current = 0;
last = elements.length - 1;
}
} else if (settings.type == "random") {
last = current;
while (current == last)
current = Math.floor(Math.random() * elements.length);
} else
alert('Innerfade-Type must either be \'sequence\', \'random\' or \'random_start\'');
setTimeout((function() {
$.innerfade.next(elements, settings, current, last);
}), settings.timeout);
};
})(jQuery);
// **** remove Opacity-Filter in ie ****
function removeFilter(element) {
if(element.style.removeAttribute){
element.style.removeAttribute('filter');
}
}
And call: Code: $(document).ready(
function(){
$('.fade').innerfade({
animationtype: 'fade',
speed: 750,
timeout: 5000,
type: 'random',
containerheight: '1em'
});
});
Hi - I have the following requirement for a textarea: Limit the number of lines to 8 Limit the number of characters to 20 per line Force a line beak when the user reaches he end of a line but break the line at the start of the last word (not half way through the word). Allow pasting into the field and auto-format the line/character count Keep he cursor where it should be (don't move it to the end of the field after any formatting) This is more complicated than it sounds - anyone worked on something similar? Has anyone ever tried to break up a text area into 2 lines, but at the same time each line has a limited number of characters allowed in it ? i.e. line 1 = maxcharacters = 124 , line 2 = machcharacters = 1024 (Line 2 will therefore wrap until 1024 chracters are reached) ... including spaces as characters. Something along the lines of: Code: var maxLines = txtArea.rows;
var maxChars = txtArea.rows * txtArea.cols;
countChars.value = txtArea.value.length;
countLines.value = getLines(txtArea);
document.myForm.maxLines.value = maxLines;
document.myForm.maxChars.value = maxChars;
if((txtArea.value.length >= maxChars || getLines(txtArea) >= maxLines)
&& (window.event.keyCode == 10 || window.event.keyCode == 13))
{
while(getLines(txtArea) > maxLines)
txtArea.value = txtArea.value.substr(0,txtArea.value.length-2);
while(txtArea.value.length > maxChars)
txtArea.value = txtArea.value.substr(0,txtArea.value.length-2);
alert("chars and / or lines limit reached");
}
else if(txtArea.value.length > maxChars )
{
while(txtArea.value.length > maxChars)
{
txtArea.value = txtArea.value.substr(0,txtArea.value.length-1);
}
alert("chars limit reached");
}
else if (f (countLines.value > maxLines)
{
while(countLines.value > maxLines)
{
txtArea.value = txtArea.value.substr(0,txtArea.value.length-1);
}
alert("lines limit reached");
}
countChars.value = txtArea.value.length;
countLines.value = getLines(txtArea);
}
Thanks This is my first posting to this forum. I have list of about a thousand applications for which various outsourcing companies are supporting at different levels. I want to use the attached code to filter. For example, if I type "SOX", every row with "SOX" appears. The filter works well but when I type "S" and the information appears on row, the height of the row changes. When I type "O" it changes more. What must I change to keep the height of the rows consistent.

I need to pass two lines of code through an onClick event.... player1.sendEvent('STOP'); player2.sendEvent('STOP'); I tried Code: <a href="javascript:void(0)" onClick="player1.sendEvent('STOP'); player2.SendEvent('STOP');" title="<?php echo $list[$i]->title ?>">
only the event of player1.sendEvent('STOP'); is working... but not the second one. How do I manage this right here on the link rather than calling a fuction. Thanks Say I have a <textarea> input and I want to strip all the blank lines (lines with only whitespace). I have this regular expression, why doesn't it do anything? I've tried different variations with the flags (m and g). Code: ... var output = input.replace(/^\s*$/gm, "notworking!"); ... The very same regex works fine in my text editor (Notepad2), and I can match all empty lines. Code: LINE1
LINE4 ^(line 3 has some spaces)
should become Code: LINE1 LINE4 And when I finally do get this to work, how would I remove the empty line? Hi. I have the following line in my HTML file <table class="bz_buglist" cellspacing="0" cellpadding="4" width="100%"> And I need to use javascript to change this line to <table id="main_table" class="bz_buglist" cellspacing="0" cellpadding="4" width="100%"> . I just need to add the ID part. How can I do this? Is there a method of replacing the line, or a way to "add attribute"? thanks! kev. Hi all, I hoping somebody can help me. I'm trying to acheive a line of text (with multiple links on each line) that change at set intervals. The code below seems to be working but I can only get working links on the first line that appears. Please can somebody help a gal out? xo [CODE] <html> <head> <title>Rotating Text</title> <script type="text/javascript"> var rotatingTextElement; var rotatingText = new Array(); var ctr = 0; function initRotateText() { rotatingTextElement = document.getElementById("textToChange"); rotatingText[0] = rotatingTextElement.innerHTML; rotatingText[1] = "why won't you work!?!?!?"; rotatingText[2] = "purdy please"; setInterval(rotateText, 5000); } function rotateText() { ctr++; if(ctr >= rotatingText.length) { ctr = 0; } rotatingTextElement.innerHTML = rotatingText[ctr]; } window.onload = initRotateText; </script> </head> <body> <span id="textToChange">log into your <a href="http://www.hotmail.com/">please</a> policy.</a> | can you <a href="http://www.google.com"> me?</a> </span> </body> </html> Is there a script that automatically applies two different styles to the first two lines of text in a container, without using CSS? Example: ====== This Would be Line One as a Title with its Own Style This would be line two as a byline with a separate style This is the main text of the paragraph... etc etc. ====== Thanks for any help. Steph Hey all. I'm looking for a way to have a single, random line fetched from multiple text files, and then have that combination output somewhere, whether just to some field or another text file. For example: Text file A - I like I hate I love I despise I cherish Text file B - apples bananas oranges grapes grapefruit pineapple cherries Text file C - some of the time. most of the time. a lot of the time. pretty much never. So it would go in, get a line from each, and display something like: I love - grapefruit - most of the time. I cherish - pineapple - some of the time. etc. etc. I know it's a weird-sounding example, but you get the point. The line choices don't have to be separated by hyphens, but they preferably would be separated by something, like a comma, semi-colon, slash, whatever. I know this is pretty much a web coding forum, so that would be fine if I had to host it on my server or open it with a browser. But it would be optimal if this could be made into a standalone executable. I'm basically looking for something like Random Line Picker, just with the added functionality I mentioned. I'd be willing to make a little donation to someone if coding this would be a little difficult. Thanks! hi, Does any one knows the javascript that read step by step single line from form and then store in array , and that array use 4 further references Please help i need this Please Please Please Thanx Regards Fawad |
