JavaScript - Replacing Carriage Return With [\br] On 2 Different Forms
Hi Guys/Gals
I am trying to do a small website for our family to keep track of each other's home address and etc.. using asp for the codes .. (its been ages since i indulge myself) i have 2 forms in which in FormA, i will key in the following address 666, ST Avenue #03-09 Anchor View Residence 123456 when i click on submit it shows this on FormB 666, ST Avenue #03-09 Anchor View Residence 123456 my question is how do i get it to be shown as 666, ST Avenue #03-09 Anchor View Residence 123456 in FormB in my formB.asp, for the particular code, all i wrote was Code: {Form.address}
I am in need of advise, have been stuck here for the past 1 day, not knwing wat to start or how to start. Thank you Similar TutorialsI think I have the regex side of this script worked out. But I need help getting everything into an array for regex to read. Is there a way to use tokenizer to read everything before a carriage return? Each line should be added to an array for the regex to analyze and parse as needed. It's been ages since I touched tokenizer, so I forgot most of it. This is the text area in the html that the script should reference. Code: <textarea cols="60" rows="14" value="" id="paste" name="paste"></textarea> Thanks so much for any help you can give. Solved. thanks so much Phil!!!! Hi all I am fairly used to programming, but not javascript, and I'm struggling a bit here... I am building a string inside a variable prior to printing it on screen as follows : Code: myclock += hours+':'+minutes; where "hours" and "minutes" are variables initialised elsewhere. How can I add a carriage return or new line character to the end of this line, so that anything else cocatenated to this variable is displayed on the next line. Thanks and have a nice evening. DeeJayBee Hello all is it possible to strip leading (meaning at the VERY begining of the text) and trailing (anything at the end of the text) carriage returns with reg ex? so if smbody enters return return return start txt entry ----> keep all other returns in paragraph sloppy ending retrun return return it would remove the start and end returns I'd like to add it to this if possible. Code: comts = comts.replace(/^\s+|\s+$/g,""); // strip leading and trailing spaces low tech (validation script done trying to improve on it now) I don't understand the logic of Break, Return False, Return True. It was never really covered in our college class, and I see everyone using it. I got an A in the class, if that 'proves' that I really tried to apply myself. NOTE: I understand what the function is doing. I just don't understand WHEN to use break, return false or return true if the the translator can determine the conditional statements. PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } else return false; } if the the translator can determine the conditional statements, why not write it like this: PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; // what's the point for the 'break'? Won't the rest of the code be ignored since it passed the first condition? } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } // why not leave the last else out? is it just a 'safety' catch, in case something other than true or false is inputted? else return false; // what's the point? } Questions: Why use return true, if the translator knows it's ture? Why use "return false" if the translator knows it's false and the alert window has already gone up? why not use "break" to stop the code? Why use the "return false" at the end "else" statement? Hi room, Hey, I opened up the source code for this page in google chrome and since i'm learning javascript, i wanted see if i could "read" it and figure out what was going on. I'm am having the hardest time understanding "return false" and "return true". Could someone step me through this via interpreting this code (in bold typeface): Code: var DefaultValue = 'Search';
function clearSearch() {
if (document.searchForm.q.value == DefaultValue) {
document.searchForm.q.value = '';
}
}
function validateSearchHeader() {
if ( document.searchForm.q.value == '' || document.searchForm.q.value.toLocaleLowerCase() == DefaultValue.toLocaleLowerCase() ) {
alert('Please enter at least one keyword in the Search box.');
document.searchForm.q.focus();
return false;
}
return true;
}
Thanks! I'm using the autofill forms plugin for firefox which can be found he https://addons.mozilla.org/en-US/firefox/addon/4775 I use it to automatically fill various web forms, duh. But I would like certain values to be chosend randomly from a list I create. I contacted the developer and he said the add on probably does not need a new feature because there is a 'dynamic tags' function to fill certain forms with dynamic values (e.g. the current time or date). He has given over the project to another developer and told me I probably would find a solution in a good javascript programming forum. So here I am! Can anyone help me with this? Basically, I just need a javascript code which chooses on item from an array randomly, I guess? I'm not a programmer myself, so any help would be greatly (!) appreciated. Thanks a lot in advance for any further guidance! Note: Here are sample dynamic tags from the plugin: <datetime> new Date().toLocaleString() <useragent> navigator.userAgent <langcode> navigator.language <resolution> screen.width+'x'+screen.height <clipboard> this.getClipboardText() Is it possible, when a page is reloaded, to replace a link to a javascript in the head with a link to a different script?
hi, I am curious about the use of appendChild() here... I have a solution that does what I want it to do, like this: Code: var sidebarEntry = createSidebarEntry(poly, html); sidebar.appendChild(sidebarEntry); sidebar.replaceChild((sidebarEntry),sidebar.firstChild); but it seems to be going the long way around. Not that it matters much (I guess), but all I want to do is to add an item to the sidebar and when a new item is added, remove the existing one. I tried just using relaceChild() on its own, but the code seems to need something to be replace... Is the above the best way to do it? Or is it possible to set the child to some dummy position like null to begin with, so that the code is not constantly reloading and replacing items (which is what I understand is going on now)? here's the page I'm working on, if you want to see the rest of the code. I appreciate any thoughts. Hey guys... Basically I need a function that will remove numerous elements from a page based on their class. I then also need a function to bring those elements back afterwards. If anyone is wondering, I'm trying to add buttons to remove/add images. Thanks! I'm sorry this is simple, but: Code: function printInput(f){
var ifr = window.frames['printFrame'];
var v1=readCookie('lesson');
if (v1==1){v2='WORKNOTEPAD1'}
if (v1==2){v2='WORKNOTEPAD2'}
if (ifr){
ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');
ifr.focus();
ifr.print();
}
else { something }
}
In this line: Code: ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');
How can I make it stop erroring and act as if the "v2" were, say, "WORKNOTEPAD2"? If the line contains the string it all works fine. It must be so simple... Hi, I am quite new to JS and is currently building a website with a little of JS Function. Ok, so I have a Page tat consists of 10 images. Each images when on mouse over, will display a larger version on the images, using JS(onmouseover). Then, I will have a next button that will replace all the images, using Ajax, which means my page will not be reloaded. The problem comes here when I have to replace all the onmouseover effect. I can replace all the thumbnails without problem, but the onmouseover I have problem replacing. Is there anyway that I can dynamically replace all the onmouseover? Any help will be appreciated. Thanks Hi, I know how to replace all the + signs in a url string by spaces, like this: newstring=oldstring.replace(/[+]/g," "); but how do I replace a substring by a comma easily? This doesn't do it: newstring=oldstring.replace(/[&menuitems]/,","); Thanks in advance for any help. I have the following code that works fine: Code 1 Code: <script type="text/javascript">
AJS.AEV(window, 'load', function() {
GB_show("Special Presentation", "http://www.site.net/temp/images/ads/special.jpg", 352, 600);
});
</script>
I also have the following code that works fine: Code 2 Code: function DoTheCookieStuff()
{
visited=getCookie('visited');
if (visited==null)
{
setCookie('visited','yes',365)
MyWindow=window.open('http://www.site.com','MyWindow','toolbar=yes,location=yes,directories=no,status=yes,menubar=yes,scrollbars=yes,resizable=yes,width=640,height=480,left=1,top=1');
}
}
However, I want to replace the blue code in the Code 2 immediately above that opens the window with the red code in the Code 1 section that opens the GreyBox window. I tried the following but it's just not working: Code: function DoTheCookieStuff()
{
visited=getCookie('visited');
if (visited==null)
{
setCookie('visited','yes',365)
AJS.AEV(window, 'load', function() {
GB_show("Special Presentation", "http://www.site.net/temp/images/ads/special.jpg", 352, 600);
});
}
}
Thank you. 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. I have 16 links on a page, when each link is clicked, I need to change text that is on the page. This is Page 1 link 1 This Is Page 1 link 2 This is Page 2 ... link 16 This is Page 16 How can I do this? Excuse my ignorance, this is my first JS project I'm a bit of a Javascript noob, so please bear with me! I'm trying to create a piece of code that will check a webpage and replace any instances of a specific line of HTML with another line of HTML. The code I have so far doesn't work, but I have a feeling that's down to my awful Javascript skills! For example, in the following code I'd want to replace all instances of <li><a href="index.pdf">Index</a></li> with <li><a href="contents.pdf">Contents</a></li> Code: <div id="downloads">
<p>Please click on your downloads below:</p>
<ul>
<li><a href="index.pdf">Index</a></li>
<li><a href="chapter1.pdf">Chapter 1</a></li>
<li><a href="chapter2.pdf">Chapter 2</a></li>
<li><a href="chapter3.pdf">Chapter 3</a></li>
<li><a href="credits.pdf">Credits</a></li>
</ul>
</div>
The Javascript I have so far is: Code: <script type="text/javascript">
var aEls = document.getElementsByTagName('a');
for (var i = 0, aEl; aEl = aEls[i]; i++) {
aEl.href = aEl.href.replace('index.pdf','contents.pdf');
}
Obviously this is meant to just replaces the a href elements, but I got a bit stuck after this! Any pointers would be much appriciated. Hey folks. I currently have a PTZ camera that is taking screenshots every minute (or so) and sending a copy of that image (overwriting the previous one) to my website. Basically, the visitors to the website will be greeted with a live screenshot. The problem is if the visitor hits the website at just the right time, the screenshot won't be loaded completely while the 2nd most screenshot is being overwritten... creating an empty image load (the dreaded red X). What I am looking to do with Javascript is to be able to load a generic image in the scenario in which no image loads. Is that possible? I tried doing something like the following and onload-ing it, but it wouldn't work. Any help would be appreciated. Thanks! Code: <script type="text/javascript">
<!--
function replaceSrc() {
var images = document.getElementsByTagName('img');
for(var i = 0; i < images.length; i++) {
var img = images[i];
if(img.src.length == 0) {
img.src = 'images/garbage.gif';
}
}
}
-->
</script>
Ok, i have a javascript that creates a table then appends it to an empty div. This works fine in FF, however it fails to work in IE8. [edit] I have decided to post the entire code since I wasn't having any luck getting any suggestions. Maybe now someone can help me out. Code: function createTable() {
var machine = document.Catalog.machine.value;
var dSearch = document.Catalog.dSearch.value;
var section = document.Catalog.section.value;
var x = xmlDoc.getElementsByTagName('record');
var y = xmlDoc.getElementsByTagName('data');
var newEl = document.createElement('TABLE');
newEl.className = 'resultsTab';
var tmp = document.createElement('TBODY');
newEl.appendChild(tmp);
var row = document.createElement('TR');
var n = 1;
var headings = new Array("Col1", "Col2", "Col3", "Col4", "Col5");
var dcount = 0;
//for (t=0;t<10;t++) {
for (t=0;t<y[0].childNodes.length;t++) {
if (y[0].childNodes[t].tagName == "record") { // it is required for FF to work properly
dcount++;
}
}
if (document.Catalog.thumbImg[0].checked) {
var container = document.createElement('TH');
var theData = document.createTextNode("Pic");
container.className = "topline1";
container.appendChild(theData);
row.appendChild(container);
}
for (h=0;h<headings.length;h++) {
var container = document.createElement('TH');
var theData = document.createTextNode(headings[h]);
container.className = 'topline' + n;
container.appendChild(theData);
row.appendChild(container);
n++;
}
tmp.appendChild(row);
switch (searchtype) {
case 1:
var objRegex = new RegExp(machine);
break;
case 2:
var objRegex = new RegExp(section, "i");
break;
case 3:
var objRegex = new RegExp(dSearch, "i");
break;
default:
document.getElementById("replaceTxt").innerHTML = "<p>There was an error processing your request.</p>";
}
var rowColor = 1;
var noResult = "false";
for (i=0;i<dcount;i++) {
var row = document.createElement('TR');
var searcharr = new Array();
for (j=0;j<x[i].childNodes.length;j++) {
if (x[i].childNodes[j].nodeType != 1) continue;
searcharr.push(x[i].childNodes[j].firstChild.nodeValue);
}
var searchstrg = searcharr.toString();
if (searchstrg.match(objRegex)) {
var t;
var m=1;
if (document.Catalog.thumbImg[0].checked) {
var pn = "images/"+searcharr[2]+".jpg";
var container = document.createElement('TD');
var refLink = document.createElement("A");
refLink.setAttribute('href', "javascript:viewImg(\""+pn+"\")");
var imgHolder = document.createElement("IMG");
imgHolder.setAttribute("src", pn);
imgHolder.style.height = "75px";
refLink.appendChild(imgHolder);
container.appendChild(refLink);
container.className = "img"+rowColor;
row.appendChild(container);
}
for (t=0; t<searcharr.length; t++) {
container = document.createElement('TD');
var theData = document.createTextNode(searcharr[t]);
container.appendChild(theData);
container.className = 'line' + rowColor + '_' + m;
row.appendChild(container);
m++;
}
tmp.appendChild(row);
rowColor == 1 ? rowColor++ : rowColor--;
document.getElementById("replaceTxt").innerHTML = "";
document.getElementById("replaceTxt").appendChild(newEl);
noResult = "true";
}
}
if (noResult=="false") {
document.getElementById("replaceTxt").innerHTML = "<h3>Sorry, there was no match to your search. Please try again</h3>";
}
}
xmlDoc is the xml object from my import xml function. it is working correctly. IE does not give any JS errors, it just does nothing. If I put text in the Code: document.getElementById("replaceTxt").innerHTML
field, IE displays the text in the correct spot so I know the code is working. I also verified the data is being written correctly to "newEl" via IE 8 debugger. IE just does not want to append the newEl child to the <div> tag. This is where I assume the problem is. Code: var bakaBanner;
bakaBanner = document.getElementById('head');
if (bakaBanner) {
var str=/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/;
document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png"));
}
Alright, here's the deal... This is a script to be used in Greasemonkey. The page this is for changes their banner every 5 minutes, the name changes and it could be either jpg or png. I'm fairly certain my regex itself: \/images\/banners\/[A-Za-z0-9_]+.[a-z]+ Is correct... Here's an example of what it's looking through: Code: <div id="head" style="background-image: url(/images/banners/kiminitodoke.jpg);" > <div id="header_left"> <div id="rss"> My guess is that it has something to do with this line: document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png")); I'm new with Javascript, so I don't really understand why it's not working... :/ |
