JavaScript - For... In Has Extra Elements
I have a webpage which has the prototype library in it as well as my own script. I just started on it, but I've already run into issues using the for... in loop. I'll admit, I'm a complete noob at javascript, so this is probably something pretty simple.
Code: function prepareToolBar()
{
//define toolbar tool names
var toolbar = [
'line',
'circle',
'ellipse',
'square',
'rectangle',
'text'];
for (var i in toolbar)
{
var tmp = document.createElement("p");
tmp.appendChild(document.createTextNode(toolbar[i]));
document.body.appendChild(tmp);
}
}
addLoadEvent(prepareToolBar);
function addLoadEvent(func)
{
var oldonload = window.onload;
if (typeof oldonload != 'function')
{
window.onload = func;
} else {
window.onload = function() { oldonload(); func(); }
}
}
Below is the output on the page from the function: Code: circle
ellipse
square
rectangle
text

As you can see, it shows the 6 elements in the array that I want, but it also shows random elements. By the way, I can fix this by changing it to a normal for loop, but I want to know what I'm doing wrong. Similar TutorialsI have a mortgage calc that is adding an extra decimal place to my interest rate. To see this in action go to: http://www.keithknowles.com/elmtree/mortgagecalc2.htm Change the interest rate to 7.5 Click Calculate Payment Click Create Amortization Chart On the following screen you'll see a recap of your data and the interest rate will now say 7.55.

Thanks. hi guys i have a form and i am using javascript to make the password. The problem is i want to use multiple users however it doesn't work when i place a comma in so do you have any suggestions? i will put the code below thanks. Code: /*the following code checkes whether the entered userid and password are matching*/ if(form.userid.value == "darran" && form.pswrd.value == "password") I integrate TinyMCE with a web application. After plugging in TinyMCE, a textarea shows up on a place where no textarea is defined. So far, this problem happens on a web page with multiple textareas. It seems to be caused by either <fieldset> tag or a <TEXTAREA .. readonly>. A non-defined textarea shows on the top of these elements. Does anyone else run into the same problem? Thanks. Hi-- I have found a neat trick to refresh an iframe in an html page, but I just need one little twist to make it work just right. I would like to make the iframe content refresh just once, not matter how many times the link is clicked... Right now, I have this in the head: Quote: <script type="text/javascript"> function refreshIframe(el) { var f = document.getElementById(el) var rsrc = f.src f.src="about:blank" f.src=rsrc } </script> And this is the link which, when clicked, refreshes the iframe every time it is clicked: Quote: <a href="#page_7c" onclick="refreshIframe('test'); return false"> "test" is the id of the iframe. I am sure how to do this is really simple, but it escapes me... Many thanks! Hello. I'm trying to open extra information if a user clicks on a TD, and close it if he click on it again. How I can do this? All I learned to do is to show it, but I can't find something that hide it if I click on the same place. Thanks for help. __________________ הורדות Hello all, Sorry for not reading the "posting guidelines" earlier. I understand that you guys are not reading/loading complete codes, my bad. Let me try again. This is a code for checking numbers A1 -> B1, when there is a match, the code will be green, otherwise black. Can somebody explain to me how I can extend this script, that more then one array is checked?? Code: <script type = "text/javascript">
var a1 = ["2","5", "11","16","23","45", "46"];
var b1 = ["2","3","8","12","23", "37", "41", "45", "48"]
for (var i = 0; i< a1.length; i++) {
for (var j = 0; j< b1.length; j++) {
if (a1[i] == b1[j]) {
a1[i]= "g"+ a1[i];
}
}
}
for (var i = 0; i< a1.length; i++) {
if (a1[i].substr(0,1) == "g") {
a1[i] = a1[i].substr(1,20);
document.write("<font color = 'green'>", a1[i] + "    ");
}
else {
document.write("<font color = 'black'>", a1[i] + "    ");
}
}
document.write("<br><br>");
for (var j = 0; j< b1.length; j++) {
document.write("<font color = 'black'>", b1[j] + "    ");
}

Thanks a ton in advance I have just used an Analysis Quiz tool (on this page http://javascript.about.com/library/blquizf.htm) to create a quiz which doesn't have right or wrong answers but adds the scores of the answers together. It all works nicely, HOWEVER I require 5 answers as opposed to the maximum of four which has been offered on this site. The (partial) code is: Code: var quiz = new Array(); var r = 0;
var analPage = 'result.html';
quiz[r++] =('93726~71~1. How often do you have a drink containing alcohol?~Never~Once a month or less~2 to 4 times a month~2 to 3 times a week~0~3');
quiz[r++] =('48844~37~How many units of alcohol do you have on a typical day when you are drinking?~1-2~3-4~5-6~7-9~0~3');
I thought it would be straight forward and I could add another option at the end of each string and then change the scoring e.g. quiz[r++] =('93726~71~1. How often do you have a drink containing alcohol?~Never~Once a month or less~2 to 4 times a month~2 to 3 times a week~4 or more times a week~0~4'); but this didn't work ... please help! Thank you For various reasons, I need the value of my drop down box options to contain size information rather than price. However I would like to be able to calculate a price for the items based on what size the user selects as well as the quantity. Below is the code I came up with (which doesn't work obviously) What can I do to get this to work for me? Thanks in advance for any help! Code: <head>
<script type="text/javascript">
<!--
function calc(A,B,SUM) {
var price = document.getElementById(A).extrainfo;
var quantity = document.getElementById(B).value;
document.getElementById(SUM).value = price * quantity;
}
//-->
</script>

Ok so I have these Input boxes and select boxes on my form. I have them input this way: Code: <input type="text" name="monto[]"> So I can then parse the many that get added and removed when I submit the form, this way PHP see's them as an array. Now I have used this in the past to cycle through my inputs to check values and such on them, but with these [] it doesn't work. Code: var changeCheck = document.getElementsByName('check');
for(i=0; i<changeCheck.length; i++)
{
var enter = new Number(getEl('dueitem' + changeCheck[i].value));
if(changeCheck[i].checked == true) {
final = enter + final;
}
}
Is there a way to cycle all these elements when they are as []. Even if it's cycle them by name, though I never had a determined amount I always have the same names for the 12 different fields there are. I put this at the end of my code thinking that after the div displays (id = 'link_container') I can eliminate (id = 'link_container') from memory when the script ends so there's a place for another div (id = 'link_container') when/if there's onkeyup event. Wouldn't this little script remove any element with an id = 'link_container' ? <script type="text/javascript"> var deleteDiv = document.getElementById('link_container'); document.body.removeChild(deleteDiv); </script> Im working on a function where i need to return the active elements ID. the element will have class="main" id="1" onmouseover="showSub()"> Would someone be able to write me a simple function which simply puts the elements ID number in an alert box? I can figure out the rest i need from that . Thanks, Tom Alright,ill go straight to the problem. I want to get all the elements with a certain tag.However i can only get the first one. my code: Code: function getTags(tag) {
var x = document.getElementsByTagName(tag);
var y = x.length;
for(var i = 0; i <= y;i++) {
return x[i];
}
}

Hi, I got a table with hundreds of rows...and I want the user to be able to hide a single one by clicking on the table row. How can I do this without typing in hundreds of ids like 1,2,3,4,5... Since you can't get elements by class and ids have to unique I'm not sure how to do this. Also the order of the rows will change when they get updated so it would end up being a mess of unordered ids. Thanks. Hi all, iv'e been trying to get round this for 2 days and still nothing. What i want to do is to be able to outline elements on a page when hovered over... simple you might think. which it is. Then with the id of the item outlined when right clicked, and chose an option, other things happen. The menu side is sorted, and the hover outline is sorted. But iv'e been trying to put them both together but it wont work! This is the closest iv'e gotten, whcih runs sooooo slow. Code: $(document).ready(function() {
function elementHover(){
$("*").bind("mouseover", function(event) {
var element = $(event.target);
if($(element).attr("rel")!="rightClickMenu"){
$(element).addClass('outline-element');
if( ($(element).attr("id")!="") && (typeof $(element).attr("id") != "undefined") ){
getElementObj($(element));
$("[id!='" + $(element).attr("id") + "']").hover(function(){
$("#" + $(element).attr("id")).removeClass('outline-element');
});
}else{
return "";
}
}else{
return "";
}
});
}
elementHover();
});
the big problem being this var element = $(event.target); if i changed it to var element = $(event.target); alert($(element).attr("id")); it would open the dialog box about 10 times spitting all kinds of results. Any help would be much appreciated. I tried the following code based on a post I saw somewhere else about summing all the elements of an array together. When I tried it though I couldn't seem to get it working. Can someone please point out what I did wrong or tell me a different way to sum array elements together? Thanks. Code: <script type="text/javascript">
Array.prototype.sum = function() {
for (var i = 0, L = this.length, sum = 0; i < L; sum += this[i++]);
return sum;
}
var myArray=[1,2,3,4,5];
document.write(myArray.prototype.sum);
</script>
Hi, I am trying to display some xml elements that are formatted like this: Code: <line> <route> <dirs>1. Head west on Calzada Roosevelt</dirs> <time>4.6 km - about 15 mins</time> <dirs>2. Continue on Carretera Interamericana/Pan American Hwy</dirs> <time>15 km - about 12 mins</time> <dirs>3. Look for turnoff at San Lucas and follow signs from there</dirs> <time>13.5 km - about 15 mins</time> </route> </line> using this js: Code: for (var a = 0; a < lines.length; a++) {
routeInfo = lines[a].getElementsByTagName("route");
for (var p = 0; p < routeInfo.length; p++) {
var time = GXml.value(routeInfo[p].getElementsByTagName("time")[0]);
var dirs = GXml.value(routeInfo[p].getElementsByTagName("dirs")[0]);
way+='<b>'+dirs+'</b>'+'<br>'+time+'<br>';
("way" eventually gets passed as the text to display) Which works OK (as you can see here if you select from Guatemala City to Antigua), but the problem is that it only shows the first set of directions, ie Code: <dirs>1. Head west on Calzada Roosevelt</dirs> <time>4.6 km - about 15 mins</time> I can see that this is because of the [0] in the getElementsByTagName - if I change it to 1 or 2 it shows the 2nd or 3rd set of directions. But I want it to show all of them... and I thought that being in a loop it would, but I'm obviously missing something. Any ideas? Thanks in advance. Hi again!! This is my code to add and delete dynamic rows and auto calculate the amount field by multiplying qty and rate. PHP Code: <form name="staff_reg" action="<?php echo $_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING']; ?>" method="post" enctype="multipart/form-data"> <table width="100%" border="0" cellspacing="0" cellpadding="2"> <table border="0" cellpadding="1" cellspacing="0" class="normal-text" align="left"> <tr align="center"> <td width="10" class="forhead" style="white-space:nowrap;"> </td> <td width="92" class="forhead" style="white-space:nowrap;">Qty</td> <td width="94" class="forhead" style="white-space:nowrap;">Rate</td> <td width="94" class="forhead" style="white-space:nowrap;">Amount</td> </tr> </table> <tr align="left"> <td class="forhead" style="white-space:nowrap;"><input type="button" value="Add Row" onClick="addRow('dataTable')" > <input type="button" value="Delete Row" onclick="deleteRow('dataTable')" ></td> <table border="0" id="dataTable" cellpadding="1" cellspacing="0" class="normal-text"> <tr> <td width="10" class="forhead" style="white-space:nowrap;"><input type="checkbox" name="chk[]"/></td> <td width="92" class="forhead" style="white-space:nowrap;"> <input type="text" name="qty[]" style="width:80px;" onblur=""> </td> <td width="94" class="forhead" style="white-space:nowrap;"> <input type="text" name="rate[]" style="width:80px;" value=""></td> <td width="94" class="forhead" style="white-space:nowrap;"> <input type="text" onblur="getValues('qty[]','rate[]','amt[]')" name="amt[]" style="width:80px;"></td> </tr> </table> <table border="0"> <tr> <td>Total:</td> <td><input type="text" name="total[]" style="width:80px;" value=""></td> </tr> <tr> <td colspan="2"> <input name="Submit" type="submit" value="Save" style="text-decoration:none" /> <input type="reset" value="Cancel" onclick="window.location.href='<?php echo $_SERVER['PHP_SELF'];?>'"> </td> </tr> </form> <script type="text/javascript"> function getValues(objName,objName2,objName3) { var var3 = ""; var arr = new Array(); arr = document.getElementsByName(objName); arr2 = document.getElementsByName(objName2); arr3 = document.getElementsByName(objName3); for(var i = 0; i < arr.length; i++) { for(var i = 0; i < arr2.length; i++) { for(var i = 0; i < arr3.length; i++) { var obj1 = document.getElementsByName(objName2).item(i); var var2 = obj1.value; var obj = document.getElementsByName(objName).item(i); var var1 = obj.value; var obj3 = document.getElementsByName(objName3).item(i); var var3 = obj3.value; var var4 = var1 * var2; document.getElementsByName(objName3).item(i).value=var4; } } } } function addRow(tableID) { var table = document.getElementById(tableID); var rowCount = table.rows.length; var row = table.insertRow(rowCount); var colCount = table.rows[0].cells.length; for(var i=0; i<colCount; i++) { var newcell = row.insertCell(i); newcell.innerHTML = table.rows[0].cells[i].innerHTML; //alert(newcell.childNodes); switch(newcell.childNodes[0].type) { case "text": newcell.childNodes[0].value = ""; break; case "checkbox": newcell.childNodes[0].checked = false; break; case "select-one": newcell.childNodes[0].selectedIndex = 0; break; } } } function deleteRow(tableID) { try { var table = document.getElementById(tableID); var rowCount = table.rows.length; for(var i=0; i<rowCount; i++) { var row = table.rows[i]; var chkbox = row.cells[0].childNodes[0]; if (null != chkbox && true == chkbox.checked) { if (rowCount <= 1) { alert("Cannot delete all the rows."); break; } table.deleteRow(i); rowCount--; i--; } } } catch(e) { alert(e); } } </script> I would like to know that how can I show the value of all the elements in array "amount" in total field?? |
