JavaScript - How To Have A Multi Line String
Is there any way to have a multiline text string in javascript? For example
strname="line one of string line two of string"; I get an error that the string is not terminated. The reason I want to do this is from the following code: Code: <textarea name="comments" id="comments" cols="90" rows="8" ></textarea>
<?php if (isset($_REQUEST["registered"]))
{
$end_of_line=chr(10);
$carriage_return=chr(13);
$step1=str_replace($carriage_return,"",$comments);
$step2=str_replace($end_of_line,"<br>",$step1);
echo "<script type='text/javascript'>\n";
echo "intermediate='",$step2,"';\n";
echo "comment_value=",'intermediate.replace(/<br>/g,"\n")',";\n";
echo "document.getElementById('comments').value=comment_value;</script>\n";
}?>
I an getting the value to set a textarea to from the server. It may have newline characters. If there is a way to have a multiline string, then I could skip all the steps and just echo one javascriopt command. Can this be done? CraigRS Similar TutorialsHey very quick question how could I do this? Basicly I have this html code. Code: <div id="editor"> <div id="tools"></div> </div> Now my javascript mods the editor by using the 'editor' id how can I use the variable for the 'editor' to look inside itself for the id 'tools', a bit like this and I know this doesn't work as I tried it but how could I do this. Code: var editor = document.getElementById('editor'),
tools = editor.getElementById('tools');
// Basicly it will have the editor as the root so
// if tools is also somewhere else on the page it
// wont pick it up, id's will never be 2 the same
// but just in-case there is lol.
Hi, I'm having trouble figuring out why my image is disappearing when the user clicks on the arrow image to expand text for viewing.

I have attached the images. Thanks in advance Hey all, I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function: Code: <body> <select> <option value="createMsg">Add Message</option> <option value="removeMsg">Remove Message</option> </select> </body> Code: var menu = {
handleMenu : function(callback){
if(callback === "string"){
menu[callback]();
}
else {
console.log("Issue occurred")
}
},
createMsg : function(){
var content = document.createTextNode("Please give additional information."),
heading = document.createElement("h1");
heading.appendChild(content);
document.body.appendChild(heading);
},
removeMsg : function(){
}
}
document.getElementsByTagName('select')[0].onchange = function(){ menu.handleMenu(this.value)};
callback should be a string so why is it saying otherwise? Thanks for response I have a problem with some forms and utilizing the proper code to make them work. Need some help if anyone out there has some working knowledge could help let me now, anyone ?? Eric I will post the code and the problem if someone would chim in thanks Hi there, I have a couple of scripts which both do exactly what I want, but when I try use them both at the same time only one of them will work, could you tell me if i need to change anything in them to get them both to work at the same time or if im missing something really simple? Thanks Script 1 Code: <script type="text/javascript">
var imgPaths = ['pic1.jpg',
'pic2.jpg',
'pic3.jpg',
'pic4.jpg',
'pic5.jpg'];
//preload the images
var imgObjs = new Array;
for(var i=0; i < imgPaths.length; i=i+1) {
imgObjs[i] = new Image();
imgObjs[i].src = imgPaths[i];
}
function togglePic(num) {
if(currPic == 0 || currPic != num) {
document.getElementById("image").src = imgObjs[num].src;
currPic = num;
} else {
document.getElementById("image").src = imgObjs[0].src;
currPic = 0;
}
}
//load the default image
window.onload=function() {
document.getElementById("image").src = imgObjs[0].src;
currPic = 0; //flag storing current pic number
}
</script>
Script 2 Code: <script type="text/javascript">
window.onload=function () { setStyles(); };
function setStyles() {
ids = new Array ('style1','style2','style3','style4');
for (i=0;i<ids.length;i++) {
document.getElementById(ids[i]).className='';
document.getElementById(ids[i]).onclick=function() { return Cngclass(this); }
}
}
function Cngclass(obj){
var currObj;
for (i=0;i<ids.length;i++) {
currObj = document.getElementById(ids[i]);
if (obj.id == currObj.id) {
currObj.className=(currObj.className=='')?'selected':'';
}
else { currObj.className=''; }
}
return false;
}

ok before i ask my question, please dont tell me to use php...i have my reasons for not doing so...and also, i would like to avoid cookies and ajax....that being said, lets see if you guys can help me out.... ive got a home page with a section where i have links....now, all those links actually go to the same page called services.html ....my problem is this....depending on what link they clicked, the page will display different information...and i cant for the life of me figure out out how to find out which link they clicked from the home page while in services.html....is there a way in my home page to create a variable that is usable on all pages that the person navigates to within my website? like a kind of global or something?? also, is there already a document object that tells me their history of what links they clicked....what im trying to do is contingent on knowing what link they clicked on the home page....basically, services.html has the same links as the home page; however, when i click each one, the innerHTML is changed to display the correect info...i just want to make it so that the home page tells services.html which link was clicked....or if thats not possible, maybe when i click one of the links on the home page, it takes me to services.html and activates one of services.html's links since it has the same links as the home page, except it has them working. now lets also get a little creative...i dont know much javascript, but i do know you can create a new window and hide it...if i create a new window, will it be accessible from another page? because i can put variables in that window maybe or even use the name of the window as a holder...im thinking outside the box here but please help me out...im new to javascript Hi i am working on a website project.. in which i have like.. for the menu.. i have a horizontal menu.. with three tabs for eg... Home , about us, contact us and.. when i click on the Home tab, i need a horizontal submenu with four or five links.. say for eg : menu1,menu2,menu3,menu4,menu4 and menu5 and when i click on menu1 i need a vertical menu on click of of menu1. so i need two horizontal menu and one vertical menu. i have attached a sample image of my menu. please have a look. Can i do this in javascript.. I need to do this using html , css or jquery.. How do i ... Please help me Hey everyone, I need some help with a function. I'm using ajax to grab a response from a PHP page, on success, the ajax sets a variable. After the line that calls the ajax function is the line the returns the variable (a global variable). Problem is, because the variable is returned right after the ajax function is fired, it doesn't give the ajax enough time to set the variable. The work around I've thought about would be using the ajax function as a variable, and returning that variable in the initial return line. Could anyone either help me with a better solution, or tell me what I'm doing wrong? Here's some code for reference: The function that will return the response I'm trying to collect: Code: function lt_ajaxGet(hash) {
var params = "hash=" + escape(encodeURI(hash));
makePOSTRequest('hash.php?get', params);
return ajax_response;
}
The ajax code: Code: if(http_request.status == 200){
ajax_response = http_request.responseText;
}

I've been searching for a multi-answer script for a 'sort of' quiz I'm making (it's not really a quiz, but I figure it's a similar concept). Example of what I want: Please Select which recipe you'd like: [checkbox1] Chocolate Brownies [checkbox2] Chocolate Chip Cookies [checkbox3] Strawberry Cake [checkbox4] Apple Pie |Submit| If they choose only Chocolate Brownies, then it'll take them to a page with just the brownie recipe, but if they choose Chocolate Brownies and Chocolate Chip Cookies it should take them to a second page I'll make with both recipes on it, etc. I know it's a lot of pages based on how many possible selections, but that's as far as my knowledge goes on how to do this. Any help would be SO appreciated! Thanks, Shia EDIT: I'd like the new information to appear in a new window for easy printing. hi i am writing a code which needs multi event that's not my problem but it is about mouse event my html is like this Code: <form> d:<input type='text' name='dlink' id='dlink' onkeypress='a()'><br /> m:<input type='text' name='mlink' id='mlink'> </form> i want to perform any changes on dlink to mlink for example i'm using onkeypress so if a user used mouse [right click and then paste] it not works any event like onmouseover or onfocus or ... do not solve my problem i found out that IE has onpaste but other browser not so help me what should i do? I was wondering, could you have more than one username and password for the Username and Password II script? and if so, could you tell me how?
I have two known methods of creating a javascript array: 1) Double brackets such as: Code: var animation_JD = [[]]; 2) Create and array then create an array inside each array element manually which is the most common method as far as I know. The problem is that the second method requires the array be be defined in size and I require a 2D array, 3D array and 4D array. Using the second method uses far to much memory to be plausible, unless there is a way to make arrays smaller by defining parts of them as integers only? Otherwise for the 1st method I described I don't know how to loop through all elements of the array such as: Code: for(group in animation_JD){
}
So does anyone have another way of creating arrays, defining an array as integers only(ideally not every part of the array) to save memory, or a way to loop through arrays created in the first method? Thanks! Anyone have a script that has multi timers that will loop; Sort of like the ones used in reverse auctions. First timer 1:24:59:59 (days/h/m/s) Second timer 1:00:00 (h/m/s) Third timer 1:59 (m/s) Forth timer 59 (s) I have one now that I found here and makes no sense to me; PHP Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title></title> <font size="-4"><font face="bold"> <script language="JavaScript" type="text/javascript"> /*<![CDATA[*/ function zxctElsByClass(zxccls,zxcp,zxctag) { var zxcexa=zxccls.indexOf('=='); zxccls=zxccls.replace(' ==','').replace(/ss/g,' '); var zxcclss=zxccls.split(' '); zxcp=zxcp||document; zxcp=typeof(zxcp)=='object'?zxcp:document.getElementById(zxcp); zxctag=zxctag||'*'; var zxcels=zxcp.getElementsByTagName(zxctag),zxcary=[]; for (var zxc0=0;zxc0<zxcels.length;zxc0++){ for (var zxc0a=0;zxc0a<zxcclss.length;zxc0a++){ var zxcreg=new RegExp('\\b'+(zxcexa<0?zxcclss[zxc0a]:zxccls)+'\\b'); if ((zxcclss[zxc0a])&&zxcreg.test(zxcels[zxc0].className)){ zxcary.push(zxcels[zxc0]); break; } } } return zxcary; } function Upgrading(hrs,mins,secs){ hrs=zxctElsByClass(hrs); mins=zxctElsByClass(mins); secs=zxctElsByClass(secs); for (var zxc0=0;zxc0<hrs.length;zxc0++){ hrs[zxc0].oop=new UpgradingOOP(hrs[zxc0],mins[zxc0],secs[zxc0]) } } function UpgradingOOP(hrs,mins,secs){ this.time=[hrs,mins,secs]; this.cng(); } UpgradingOOP.prototype.cng=function(){ var hours=this.time[0].firstChild.data; var mins=this.time[1].firstChild.data; var secs=this.time[2].firstChild.data; secs=secs-1; if (secs<0){ mins=mins-1; secs=59; } if (mins<0){ hours=hours-1; mins=59; secs=59; } if (hours<0) { hours=0; mins=0; secs=0; this.time[0].firstChild.data=hours; this.time[1].firstChild.data=mins; this.time[2].firstChild.data=secs; window.location = document.URL; } if (mins>=0) { mins=mins-1; mins=mins+1; if (secs<10) secs="0"+secs; if (mins<10) mins="0"+mins; this.time[0].firstChild.data=hours; this.time[1].firstChild.data=mins; this.time[2].firstChild.data=secs; this.to=setTimeout(function(zxcoop){return function(){zxcoop.cng();}}(this),1000); } } /*]]>*/ </script></head> <table align=\"left\" width=\"50\" height=\"50\" border=\"0\" bgcolor=\"ltblue\"> <tr> <td><label class='uHours' >1</label>: <label class='uMins'>1</label>: <label class='uSecs'>1</label></td> <td><label class='uHours' >1</label>: <label class='uMins'>1</label>: <label class='uSecs'>1</label></td> <td><label class='uHours'>1</label>: <label class='uMins'>1</label>: <label class='uSecs'>1</label></td> </tr> </table> <br /> <table align=\"left\" width=\"50\" height=\"50\" border=\"0\" bgcolor=\"ltblue\"> <tr> <td><label class='uHours' >1</label>: <label class='uMins'>1</label>: <label class='uSecs'>1</label></td> <td><label class='uHours' >1</label>: <label class='uMins'>1</label>: <label class='uSecs'>1</label></td> <td><label class='uHours'>1</label>: <label class='uMins'>1</label>: <label class='uSecs'>1</label></td> </tr> </table> <script type="text/javascript">Upgrading('uHours','uMins','uSecs');</script> </font></font> </body> </html> Hi, I have a question about an oop/class style form of javascript programming.

Hello Im after a very specific layout for my dropdown menu. Basically 3 menu boxes listed vertically in a table and then an iframe underneath. When a user selects an option in box 1 , i would like a specific list of options to be displayed in box 2 . The options shown in box 2 must be dependent on box 1 i.e. as the box 1 selection changes , so do the box 2 options. Same thing applies with box 3 - when the user changes box 2 , i would like a specific list of options displayed in box 3. Then when a selection is made in box 3 , i want a certain page to load in an iframe below the 3 boxes. If you could also populate each box with some sample data so i can replace it to fit my site as needed by myself :-) So in a nutshell:- User Clicks Box 1 --> Specific Options Appear In Box 2 User Clicks Box 2 --> Specific Options Appear In Box 3 User Makes A Choice In Box 3 --> Specific Page Loads In Iframe Below (Already Got This Bit Figured Out) Help much appreciated on this. I eagerly await a response :-) |
