JavaScript - Replace Not Working For Some Reason
I am trying to fix some datetime strings so I can convert form values into date objects so I can compare the dates in my validation process. the date time strings look like - 7/21/2011 8:00am
for some reason the am is not being replaced by " am" . here's the function Code: function ampm(str){
str.replace(/am/gi," am")
str.replace(/pm/gi," pm")
return str
}
for example the result of ampm("8:00am") is 8:00am and not 8:00 am .. it seems so simple. Similar TutorialsHi there, i have this simple script that replaces the scrollbar of an iframe called iFrame1 with 2 up and down arrow images, but it only works in IE, i've tried it in Chrome and Firefox... here is the code Code: <script type="text/javascript" language="javascript">
function bsh_iFrame1(step,time){hs_iFrame1=setInterval("sh_iFrame1("+step+")",time)}
function esh_iFrame1(){clearInterval(hs_iFrame1)}

scrolly=scrolly+step
iFrame1.window.scroll(scrollx,scrolly)

} else {
alert('Please select a unique name for the new staff member\nadd a middle initial maybe?');
}
}
if i alert(unique) it tells me 'true' (string) but still doesnt go into the create part of the script, i just get the alert('Please select a unique name for the new staff member\nadd a middle initial maybe?'); any ideas? i know im probably missing something basic but its really annoying lol btw - the php for the _check_username.php is simple: PHP Code: <?php if(!isset($_SESSION)) {session_start();} if($_SESSION['authorised'] != true) { exit; } include 'config.php'; include 'opendb.php'; $user = $_REQUEST['user']; $query = "SELECT user FROM user WHERE user='$user'"; echo $query; $result = mysql_query($query) or die('false'); $row = mysql_fetch_array($result, MYSQL_ASSOC); if($row) { echo 'false'; } else { echo 'true'; } mysql_free_result($result); ?> Hi all. Can someone please help me make this code accurate so it counts the correct number of characters? when u click on the box, it should display 0. when u type in the box, it should count up by 1. when u click on the box, and u delete a character or characters, it subtracts that many code: Code: <form method="POST">
<table border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="100%">
<textarea onkeyDown="count_it(this)" rows="12" name="charcount" cols="60" wrap="virtual"></textarea>
</td>
</tr>
<tr>
<td width="100%"><div align="right"><p> <input type="text" name="displaycount" size="20"></p>
</div></td>
</tr>
</table>
</form>
<script language="JavaScript">
function count_it(what){
formcontent=what.form.charcount.value
what.form.displaycount.value=formcontent.length
}
</script>
I'll probably be laughed at for this attempt of coding, but all I am trying to do is read an input field, remove the "$" and write the new value in a different input field. Code: function convert_action (form){
var input1=form.input_field1.value;
var clean=input1.replace(/$/, '');
form.input_field2.value = clean;
}
Looks simple, and thought this would work, it kindof does, it just does not strip out the dollar sign... Help would be appreciated...greatly... I have a js replace function to replace text next to two radio buttons on a pre set form. Script is as follows. Code: document.body.innerHTML = document.body.innerHTML.replace(
"Payment by <b>Moneybookers</b> e-wallet<br>", ""
);
document.body.innerHTML = document.body.innerHTML.replace(
"Maestro, Visa and other credit/debit cards by <b>Moneybookers</b>",
"Pago con Diners Club, Mastercard o Visa"
);
The script works fine in Chrome and Firefox, however, the script is not actioned in Explorer. I believe it has something to do with there being , / - within the text I am replacing? When I use the function to replace text with no , / - in the text - it works fine in explorer, however, for example when I try to replace text.. - "Maestro, Visa and other credit/debit cards by Moneybookers" this does not work in explorer.. I'm assuming because of the coma and forward slash. Honestly I've tried everything but just can not get this to work. I have no access to the HTML table where the form is posted this is why I am attempting this funtion. Any help would be greatly appreciated!! I am attempting to create a web based quote system that pops up a preview of the fencing type selected on click. but nothing works.. im frustrated with this and need a bit of guidance. hopefully someone will help here is the HTML body of the form Code: <body>

Join Date Feb 2009 Posts 28,311 Thanks 82 Thanked 4,754 Times in 4,716 Posts So have you used your error console? Or your JavaScript debugger? Hit the F12 key to bring up both. I recommend using the Chrome browser for this because I like its integration of the console and debugger, et. al., best. But any modern browser will do. Are you getting errors right off the bat from the error console? Are you getting errors when you try to select a fence, etc.? Tell us *WHAT* is going wrong. Don't make us re-construct your page so we can use our error console. And if you still can't figure it out, can you post the page LIVE someplace? Give us a URL to look at? This code snippet below was extracted from a rather large javascript. It is not written here to function alone, but it is solely to illustrate my question, Why can't a variable be read from within a function when it has been set as the text of a url address, in this case www.google.com)? When I click on the browser HREF that calls the OnClick event, the function SwitchFN, I receive the following 2 alerts: "Ones" (variable is output as expected) "undefined" (the second variable is no longer defined within the function, however using the command alert(numtwo) in the variable definition section of my code will work as expected and the alert will be "www.google.com" Why can't the function see the variable when it is a URL? Code: I have set several default variables up in the beginning of my script:
var numone = "Ones"
var numtwo = "www.google.com"
/// more variables set
/// more functions
function switchfn(nfn,nrm) {
document.cookie = "mvrfile=" + numone
alert(numone)
alert(numtwo)
}
document.write('<TR><TD BGCOLOR=# ALIGN=LEFT VALIGN=top WIDTH=60 COLSPAN=2><A HREF="#" onClick="switchfn(\'' + myview + '\',\'' + mytxt + '\')">' + mytxt + '</A></TD></TR>') ;
Hi, I'm making a Google Map that reads info from a database and pulls Twitter usernames from it to plot points on a map. In the infowindow of these points I have some code that displays the Twitter users latest tweet. There's alot of code for this map so i'll only show you the part i'm working on: Code: function readData() {
var request = GXmlHttp.create();
request.open("GET", "phpsqlinfo_result.php", true);
request.onreadystatechange = function() {
if (request.readyState == 4) {
var xmlDoc = GXml.parse(request.responseText);
// obtain the array of markers and loop through it
i=[0];
markers=[0];
map.getInfoWindow().hide();
gmarkers = [];
map.clearOverlays();
side_bar_html = "";
var markers = xmlDoc.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
// obtain the attribues of each marker
var lat = parseFloat(markers[i].getAttribute("lat"));
var lng = parseFloat(markers[i].getAttribute("lng"));
var point = new GLatLng(lat,lng);
var label = markers[i].getAttribute("name");
var address = markers[i].getAttribute("address");
var type = markers[i].getAttribute("type");
var html = '<' + 'script src="http://twitter.com/javascripts/blogger.js"><' + '/script><' + 'script type="text/javascript" src="http://twitter.com/statuses/user_timeline/' + label + '.json?callback=twitterCallback2&count=1"><' + '/script><br /><div id="twitter_update_list" style="list-style:none"></div>';
// create the marker
var marker = createMarker(point,label,html);
map.addOverlay(marker);
}
// put the assembled side_bar_html contents into the side_bar div
document.getElementById("side_bar").innerHTML = side_bar_html;
}
}
request.send(null);
}
var html is where it's all happening. I'm using the Twitter script from http://limetouch.com/article/valid-x...vascript-code/ and I have it laid out with all them ' + ' to break it up so it doesn't end the actual javascript used to create the map. I'm new to Javascript so I don't know too much. I know that this method is a really backwards way of doing it, but it works for Firefox. I'm able to retrieve the users latest tweet when I click on their map marker. What I want to know is why it doesn't work in any other browser? I've tried IE7+8, Google Chrome, Opera, and Safari and no tweet displays. Sub-question: While a tweet does display in Firefox, the infowindow doesn't resize with the dynamic content. Any way to fix that? I have the following function: Code: function sonKare(sayac, oteki) {
var vertical, horizontal = hangiYataySira(sayac, oteki), j, k,
l, m, united, tekRakam, actualV = [], actualH = [],
numaralar = [1, 2, 3, 4, 5, 6, 7, 8, 9], olmayanlar = [];
if(ilkSefer === true) {
vertical = hangiDikeySira(rakamlar.length);
ilkSefer = false;
}
else {
vertical = hangiDikeySira(rakamlar.length - 1);
}
for(j = 0; j <= vertical.length - 1; j ++ ) {
if(rakamlar[vertical[j]] !== undefined)
actualV.push(rakamlar[vertical[j]]);
}
for(k = 0; k <= horizontal.length - 1; k ++ ) {
if(rakamlar[horizontal[k]] !== undefined)
actualH.push(rakamlar[horizontal[k]]);
}
united = actualV.concat(actualH);
//---- Olmayan rakamları bulan kısım ------------
outer: for(l = 0; l <= numaralar.length - 1; l++) {
for(m = 0; m <= united.length - 1; m++) {
if(numaralar[l] === united[m])
continue outer;
if(m === united.length - 1 && numaralar[l] !== united[m])
olmayanlar.push(numaralar[l]);
}
}
//----------------------------------------------
if(olmayanlar.length > 1 || olmayanlar.length === 0) {
rakamlar = [];
document.form1.buton.click(); // THIS LINE DOES NOT WORK SECOND TIME
}
else {
$("_" + oteki + "_" + sayac).value = olmayanlar[0];
rakamlar.push(olmayanlar[0]);
sayac++;
if(sayac === 10)
return;
else
sonKare(sayac, oteki); //CALLS ITSELF
}
}
This is a recursive function. As stated above there is a line which does not work for the second time. What I mean is, it works perfect for the first time and after function calls itself, it doesn't work. Javascript does execute the line above it but just disregards that document.form1.buton.click(); line. I use Firebug for debugging and I checked it many times, when that expression needs to be executed for the second time, JavaScript just ignores it and immediately goes at the end of the function... I just can't figure out why JS does such a thing? p.s: Don't bother about weird variable names, they are not in English but in Turkish which is my native language I started on the following page (part of an asp.net solution), but the damned thing keeps reloading. Anyone able to spot the problem? Cheers! Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

i am trying to make an online graphing calculator with javascript. dont ask how because i dont know. but there is an annoying error in a do...while loop. although it should break out of the loop when the |'s (absolute value signs) are replaced with Math.abs( and ). here is the code. Code: var initec = function(){
var rg = {
}
;
rg.matc = false;
rg.i = 0;
rg.change = function(equ){
if (typeof(equ) != "string"){
alert('Equation must be a string');
return;
}
alert("starting equation: "+ equ);
rg.i = 0;
do{
rg.matc = equ.match(/\|/);
if(rg.i === 0){
equ.replace(/\|/, " Math.abs(");
rg.i = 1;
alert("1 "+equ);
}
else {
equ.replace(/\|/, " ) ");
rg.i = 0;
alert("0 "+equ);
}
}while(rg.matc)
alert("finished equation: " + equ);
}
return rg;
}
rg=initec();
rg.change("|8/x+7|-2");
the last 2 lines and the alerts are for debugging. as you can see, it is not finished. but still, it should work. Here is the link in question. I have created a small page with the isolated problem on it. http://frontendaudio.com/v/vspfiles/...pt_tester.html the javascript file that is referenced basically only does one thing. It searches for "> >" and then alerts us whether or not it's on the page. --- It pulls the innerHTML of the entire document --- the searches it - and indexes the string. I echoed the string out to a text area so you could see the string "> >" is clearly there after the word microphones in the link tag... </a> > < etc.. Any thoughts on how I can detect this string somehow? Thanks. Here is the code inside the javascript file. Code: var myStringDiscuss = 'microphones</a> >';
myStringDiscuss = myStringDiscuss.replace(/~/g,""); // unmunge
function discussDetection(){
var str = document.getElementsByTagName('html')[0].innerHTML;
str = str.toLowerCase(); // to make case insensitive
var category_string = str.indexOf(myStringDiscuss);
if (category_string == -1) {
alert("not on this page");
}
else {
alert("IS on the page");
}
}
window.onload= discussDetection;
First of all, I don't want to replace text in a form, or on click. I'm writing up a design document in HTML, and I need an area to display code. The < and > tags won't show up, obviously, but to make it easier on the programmer, I don't want him to have to manually put in < and > for each time it shows up. I am aware that JavaScript has a replace function, but I am not familiar with JavaScript quite yet. Is there a way to have JavaScript find the < and > in a certain div, and replace it with < and > on load? I would appreciate your help so much, Its been frustrating me. in the div class "done" it reads 13/34 i want to compare these to numbers like this if (13 < 34){do something()} else {return false;} so i am trying to get each number by it self to compare with. var did=m[1].getElementsByClassName("done")[1].innerText.replace(/\/.*/,"").value; this line returns 13 correctly. var need=m[1].getElementsByClassName("done")[1].innerText.replace(? ,"").value; this ? the info that i need to get for the other number. i know how to do it if it were a letter but can find the correct way being that it is a / instead. Thx I found a regular expression that will strip my string of every html tag... var stripped = htmlStr.replace(/(<([^>]+)>)/ig,""); Well, I also want it to strip every thing between parentheses, square brackets, and replace " &# 160;" with a space. It would be really cool if you could explain how to do this as well, because the stuff in the above code after "replace" confuses me. I have no idea how that's working. Hi I'm looking for a very simple script to replace one div with another. I've found a few but they seem overly complicated with features I don't need. I simply want to be able to click on a div and for it to be replaced with another div previously hidden. If someone could suggest a solution or point me in the right direction I'd really appreciate it. Thanks How would you do a .replace for a Javascript if statment.
Hi, I need function for replacing one string with some html tag (for example <div>something</div>) in web page. Tricky is that in this replacing I must ignore all text between <a> and </a>. It's look easy but I am not good in javascript.
I know how the replace method works, but I can't for the life of me figure out exactly what this replace function is doing... Can someone shed somelight for me? the g I *think* is a flag for global replacement... Code: replace(/\s/g, " "); I know that *something* is being replaced by a non-blank space, but what? |
