JavaScript - Reg X Strip Leading Trailing Carriage Returns?
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) 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.

Thank you 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 I have javascript function which calculates the product of two numbers. function fnCalculate() { var lat1=price * num; } Here for eg if price is 19.50 and num is 1 then o/p should be 19.50 and not 19.5 as its resturning now. Also if price is 15.00 and num is 1 then o/p should be 15.00 and no just 15. Is it possible ... someone please help Hi All, how do I trim leading zero in a date e.g 08/08/2003 to become 8/8/2003. thanks I have the following which returns the date in the format I need it in but it does not have the leading zero's Code: var wholeDate = getTheDay(); function getTheDay(){ var d = new Date(); var year = d.getFullYear(); var numMonth = d.getMonth() + 1; var day = d.getDate(); var whole = year + '-' + numMonth + '-' + day; alert(whole); return whole; } Would return todays date as 2012-1-5 How do I get the date returned like 2012-01-05 ? Is there any way to use javascript to strip codes or text from a webpage.
Code: <script type="text/javascript" src="external.php?type=js"></script> <script language="" type="text/javascript"> <!-- for (x = 0; x < 10; x++) { document.writeln("<a href=\"showthread.php?t="+threads[x].threadid+"\">"+threads[x].title+"</a>, "); } //--> </script> My code will display 10 posts, however at the very end it will display an extra ", " which bugs me. How can I strip those last two characters. I'm using forum with bb rich text editor, the problem that sometimes when a user copy and paste content, there ere extra codes that are not supported like: Code: [highlight=#ff0000][/highlight] [blockquote][/blockquote] [CENTER ALIGN=CENTER][/CENTER ALIGN] Can you help me to write a script that automatically reformat the html content when pasted and only keeps specified tags like [img],[url],[b], defined in array ... If it is not possible to reformat content when paste, I can add a button to the editor and call that function to format the content and return plain text with a specific tags. I tried this script: Code: function removeHtmlTag(strx){ if(strx.indexOf("[")!=-1) { var s = strx.split("["); for(var i=0;i<s.length;i++){ if(s[i].indexOf("]")!=-1){ s[i] = s[i].substring(s[i].indexOf("]")+1,s[i].length); } } strx = s.join(""); } return strx+''; } It made to strip html tags, I replaced <> with [], It removes all tags and don't put space instead of the removed tags, example: Code: hello[h1]Name[/h1] Will be like : helloName ??? I got an idea to make a stupid trick, like converting [IMG] to {IMG} and run that function and re convert {IMG} to [IMG] ... Please help, I'm not good in Regular Expressions. Thanks for your time, Regards. There is a comment section on a blog that I follow, and the blogmaster decided to try to put in a preview button. I found a site that had some code purporting to do just this http://ramui.com/Java_script_code_ex...html-code.html He pulled the code down and inserted it, making what appeared to be no significant changes. The actual code used: Code: <script type="text/javascript"> function showPreview() { var s=document.getElementById('comment').value; if((s.length>1000)||(s.length<1)){alert("Code length must be within 1 to 1000 characters."); return false;} document.getElementById('commentpreview').innerHTML=s; } </script> with the invoking code as: Code: <input type="button" value="Preview" onclick="javascript:showPreview()" /> Unfortunately, the preview strips all hard carriage returns and multiple spaces out. The result is one long paragraph that is more unreadable than the original. What can be done to keep the formatting? Code: <script type='text/javascript' src='http://www.feedzilla.com/tools/swfobject.js'></script> <script type='text/javascript'> var flashvars = {id:'5018093150881',code:'flash',c:'',scroll:'v',prov:'news',cat:'Sports',cat2:'Basketball - NBA',width:'728',height:'90',num_articles:'10',show_summaries:'Yes',show_sources:'Yes',show_dates:'Yes',related_show:'No',vid:'',title:'',title_size:'12pt',title_bold:'Yes',keywords:'',url:'',headers_size:'14pt',font_size:'10pt',font_family:'Arial',text_alignment:'Left',space:'Yes',titlecolor:'#e53211',fcolor:'#000000',desccolor:'#ffffff',sourcecolor:'#e53211',datecolor:'#888888',bgcolor:'#000000',ref:document.location.href}; var params = {scale:'noscale',salign:'lt',bgcolor:'#000000'}; var attributes = {}; swfobject.embedSWF('http://www.feedzilla.com/widgets/news-widget.swf', 'Feedzilla_news_widget_501809963', '728', '90', '9.0.0','',flashvars, params, attributes); </script> <div id='Feedzilla_news_widget_501809963'></div> That produces this: I want to get rid of that strip on the bottom that says "Get This" which stretches all the way across. Is there anything I can change in that code to make this happen? hi here is a code i use to calculate distance b//w 2 places using google api... it works perfectly and shows the results in the html but when i add a return statement at the end of the function showlocation() it returns undefined.. why it is so.. how to resolve it???

New here as you can probably tell, and I have a problem... I want to know how to find out the viewport height in IE. I have been trying to use document.body.clientHeight, which is supposedly exactly what I am after, but the results were always way too small to be the correct one. As a test, I whacked a div in my page and made it 4000px tall, and ran document.body.clientHeight from IE's debugger and it returned a number over 4000px. It seems as thought clientHeight is actually returning the total height of the document, not the viewport size. Thanks for any help. Suppose we have following javascript codes: Case 1. var foo = function () { var x = "hello"; var bar = function () { alert(x); } return bar; } var bar_ref= foo(); document.write(bar_ref()); // it pops up "hello" and print-outs "undefined". If we modified above code slightly, shown as follow: Case 2. var foo = function () { var x = "hello"; var bar = function () { alert(x); } return bar(); } var bar_ref= foo(); document.write(bar_ref()); // it only pops up "hello". As you can see, Case 2 modified the return value from "return bar" to "return bar()," which won't cause the "undefined" output. To me, it looks like when the JS interpreter executes the line "bar_ref();" it triggers the execution of function "foo", besides both "return bar" and "return bar()" do the same job which is to execute function body of "bar". The only difference is that after the execution of function bar, its function body does not exist anymore, so when the interpreter executes the line "return bar;" it follows the function identifier "bar" and ends up with "undefined". This is why the Case 1 gives us "undefined", but I am not quite clear about why the Case 2 can trace down to the function body of "bar". Do you have any ideas about such difference outputs? Dan Code: <script> // Declared Constants MORSE_ALPHABET = new Array ( '.-', // A '-...', // B '-.-.', // C '-..', // D '.', // E '..-.', // F '--.', // G '....', // H '..', // I '.---', // J '-.-', // K '.-..', // L '--', // M '-.', // N '---', // O '.--.', // P '--.-', // Q '.-.', // R '...', // S '-', // T '..-', // U '...-', // V '.--', // W '-..-', // X '-.--', // Y '--..' // Z ); CHAR_CODE_A = 65; var CTS = prompt('Enter Morse code','here') var inMessage = CTS.split(' '); searchLocation(inMessage,MORSE_ALPHABET) function searchLocation(targetValue, arrayToSearchIn) { var searchIndex = 0; // Iterative counter for(i=0;i < targetValue.length;) { targetValue = targetValue[i]; // Search until found or end of array while( searchIndex<arrayToSearchIn.length && i != targetValue.length && arrayToSearchIn[searchIndex]!=targetValue ) { i++ searchIndex++; } if(searchIndex<arrayToSearchIn.length) { return String.fromCharCode(CHAR_CODE_A + searchIndex); } else { return -1; } } } document.writeln(searchLocation(inMessage,MORSE_ALPHABET)); </script> <head> </head> <body> </body> This is my code and i have figured it to create an array from the prompt and then use the function to return the first array it finds but i cant seem to make it go on to the next index of the array. I know that when you return a value the function closes and i have tried to store my return in a variable but its not working the way i want it to or I'm not writing the correct command or is there away to do multiply returns, i think what i need to do is simply but i have been staring at this screen for a while now and just cant see it. Please help me. Thanks RESOLVED Thank you! Greetings all! Im looking for some help regarding responseText, so please have a look im so mad right now because i have been struggeling for hours XMLHttpRequestObject.responseText returns correct value when i do alert(XMLHttpRequestObject.responseText); see line PHP Code: var fnWhenDone = function (XMLHttpRequestObject) { alert(XMLHttpRequestObject.responseText); }; But problem is that i want to save down the response to a variable... so i try to change it into PHP Code: var fnWhenDone = function (XMLHttpRequestObject) { varTest = XMLHttpRequestObject.responseText; }; When i try to alert varTest later i get "Undifined"... im pretty new to javascript and have been stuck for hours ... See full code below PHP Code: var myConn = new XHConn(); if (!myConn) { alert("XMLHTTP not available. Try a newer/better browser."); } var fnWhenDone = function (XMLHttpRequestObject) { alert(XMLHttpRequestObject.responseText); }; myConn.connect("validateSearch.php", "POST", "foo=bar&baz=qux", fnWhenDone); function XHConn() { var xmlhttp, bComplete = false; try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) { try { xmlhttp = new XMLHttpRequest(); } catch (e) { xmlhttp = false; }}} if (!xmlhttp) return null; this.connect = function(sURL, sMethod, sVars, fnDone) { if (!xmlhttp) return false; bComplete = false; sMethod = sMethod.toUpperCase(); try { if (sMethod == "GET") { xmlhttp.open(sMethod, sURL+"?"+sVars, true); sVars = ""; } else { xmlhttp.open(sMethod, sURL, true); xmlhttp.setRequestHeader("Method", "POST "+sURL+" HTTP/1.1"); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); } xmlhttp.onreadystatechange = function(){ if (xmlhttp.readyState == 4 && !bComplete) { bComplete = true; fnDone(xmlhttp); }}; xmlhttp.send(sVars); } catch(z) { return false; } return true; }; return this; } Hi all, I have a simple XML file that looks something close to this: Code: <presence id="12345"> <status>in a meeting</status> <priority>1</priority> </presence> <x> <picture>blahblah</picture> </x> <x> <hash>string</hash> </x> I need javascript to pull the status from this file. Here's what I have for that: Code: <span id="login_status"></span> <span id="secondlogin_status"></span> <script type="text/javascript"> if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","https://www/user1.xml",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; document.getElementById("login_status").innerHTML= xmlDoc.getElementsByTagName("status")[0].childNodes[0].nodeValue; document.getElementById("priority").innerHTML= xmlDoc.getElementsByTagName("priority")[0].childNodes[0].nodeValue; xmlhttp.open("GET","https://www/user2.xml",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; document.getElementById("secondlogin_status").innerHTML= xmlDoc.getElementsByTagName("status")[0].childNodes[0].nodeValue; document.getElementById("second_priority").innerHTML= xmlDoc.getElementsByTagName("priority")[0].childNodes[0].nodeValue; </script> Here's my problem: If my xml file only has the one "parent" (meaning: Code: <presence id="12345"> <status>in a meeting</status> <priority>1</priority> </presence> ) this works WONDERFULLY. However, when the second and third "parents" are added (<x>), the script returns blank output in the spans. I feel almost certain my issue is related to this: http://codingforums.com/showthread.php?t=140810 but I've tried to switch that around but it doesn't seem to provide any different results. If you require a bit more info on the project itself, here's a rundown: This xml file is created by an internal chat app at my office. Each employee has their own xml file listing their current availability and status (hence "in a meeting"). This will be used to determine the availability of certain individuals in the building without having to be logged in to the chat app. That's why there's multiple xml files going to be used (roughly 10-15 in the end). I know there is probably going to be an embarrassingly simple answer to my issue (like I am pointing to the wrong place in the DOM) but here goes. Why is the value of overflow not being returned by the below script? Code: <style type="text/css"> div.fbOverflow_Scroll { position:absolute; top:20px; left:20px; z-index:27; overflow:scroll; overflow-x:hidden; height:30px; width:100px; background-color:#FFB60D; border:1px Solid #000000; } </style></head><body><form method='post' enctype='multipart/form-data' id='myForm' name='myForm'> <!-- **** lab(Box10pt, fbOverflow_Scroll, , Extra=) --> <div class='fbOverflow_Scroll' id='fbOverflow_Scroll' position=relative > This is stuff inside of a little scrolling area of the form</div> <script language="JavaScript"> alert(document.getElementById('fbOverflow_Scroll').style.overflow); </script> </form> AJAX XMLHttpRequest responseText returns undefined but alert returns expected text. Code: function getFile(fileToOpen) { var xmlhttp; if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else if (window.ActiveXObject) { // code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } else { alert("Your browser does not support XMLHTTP!"); } xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState==4) { //alert(xmlhttp.responseText); return xmlhttp.responseText; } } xmlhttp.open("GET",fileToOpen,true); xmlhttp.send(null); } Code: document.getElementById('widgetOptionsShadow').innerHTML = '<div id="widgetOptions">' + getFile('/togglePauseInit.php?g=<?php echo $gadgetName; ?>') + '</div>'; |
