JavaScript - Are Style Elements Counted In Document.stylesheets Array?
I have one question about <style> elements, are they counted in document.styleSheets array? and can I add rules to them by using insertRule() and deleteRule() methods?
Similar TutorialsHi All, I have a javascript application i have built http://dtp3.demodesign.co.uk/uploader/ Now this working in everything excluding IE but i don't under stand why it dose not work in IE it is a JSON Class that loads appends the content. and has an Iframe System to provide a powerful solution to work with AJAX to show file lists Any way if you go to that site it errors in Ie but work in every thing else any one got any idear why that is I wanted to know if document.getElementById works while accessing form elements. I tried doing this just for testing purposes This code doesnt work function validateForm() { var val = document.getElementById("id_login").getAttribute("value"); alert(val); return false; } but this does function validateForm() { alert(document.myForm.text_login.value ); return false; } Why doesnt document.getElementByid work with form objects.it works with all non form HTML objects.. I need to validate some fields on a form. I have cut the script down to bare minimum to try to isolate the errors but no luck. This is the script Code: function verifyimages(){
var errorstatus = "groovey";
var errormsg = "";
var str = '';
var elem = document.getElementById('salespageform').elements;
for(var i = 0; i < elem.length; i++) {
document.write("file type: " + elem[i].type + " <br>" );
document.write(" value: " + elem[i].value + " <br>");
}
if (errorstatus=="groovey"){
document.salespageform.submit();
return true;
} else {
alert(errormsg+"\n You can only upload a gif, jpg, jpeg or prn image");
return false;
}
}
The form that calls this code has about 30 fields some text, some file, some hidden. When I replace the section that say Code: document.write("file type: " + elem[i].type + " <br>" );
document.write(" value: " + elem[i].value + " <br>");
with this Code: for(var i = 0; i < elem.length; i++) {
str += "<b>Type:</b>" + elem[i].type + "  ";
str += "<b>Name:</b>" + elem[i].name + " ";
str += "<b>Value:</b><i>" + elem[i].value + "</i> ";
str += "<BR>";
}
document.write(str);
it works fine. But what I really want to do is check that if the file type is "file" that the value is a jpeg, prn or gif. I know how to do that with regular expressions but I am getting errors -- different ones in IE and Firebox. So the first code presented throws this error in IE It displays the first file type and then errors with the message PERMISSION DENIED I also tried the following code in the for loop Code: for(var i = 0; i < elem.length; i++) {
if (elem[i].type == "file"){
document.write('its a file');
}
}
that throws the error message that document.salespageform.submit is undefined these "seem" to work in firefox Any help is appreciated I'm reworking a 15 year old script. Here is the original general purpose routine that extracted a portion of one form to another form. Code: function FillForm(f) {
for( i=FullName; i<=EndOfForm; i++) {
self.document.forms[f].elements[i].value = FormData[i];
};
};
But NOW I'm supposed to use getElementById() Does that mean instead of the short routine I have to put one line for each Id tag and it is no longer general purpose and independent of the form being used? Is it OK to keep using the legacy script despite the Warning from the error console? Could you please help.

FF and Chrome seem to work ok, but it breaks in IE. What am I doing wrong here? I am trying to pass two inputs one hidden one text to php using document.getelementsbyname(). The hidden input is in a php array, the text input is a user typed input. When ever I pass it to php it always pulls the first item in the array. So even if I click "View" on the 3rd item in my array it will still show the two inputs from my first item in the array. Here are my html input fields followed by java function followed by submit. How do i get it to send the proper information and not the first item in the array. Code:
<input name="imageNumber" type="hidden" value="<? echo $imageNumber; ?>.png">
<input type="text" name="imprint" value="" size="40">
<script>
function passImprint() {
imageNumber = (document.getElementsByName("imageNumber")[0].value);
imprint = (document.getElementsByName("imprint")[0].value);
urlString = "imprint.php?imprint=" +imprint + "&imageNumber=" +imageNumber; window.open(urlString,"width=640,height=295");
}
</script>
<input type="button" value="View Imprint" onClick="passImprint();">

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>
Hey All, I have completed most of a homework assignment that I am working on. I am able to .push desired elements into an array: Code: //Insert variable into the Array
function insertElem(){
//Insert and sort first array, but not second array
if(nameInput.value != ""){
studName2.push(nameInput2.value);
}
else{
alert("Value to be inserted cannot be Null");
}
//Refresh display area
clearAndShow2();
}
What I would like to do is be able to store and display the created array "permanently" until I decide to remove the elements. My current method to hold the elements, until the page is refreshed, is: Code: //Refresh second array
function clearAndShow2(){
nameInput2.value = "";
messageBox2.innerHTML = "";
messageBox2.innerHTML += "Groups: " + "<br />" + studName2.join("<br />") + "<br />";
}
I appreciate the assistance. Hey guys. I need a little help with checking elements in my array. I created an array of size 50 and initialized all elements to 1. What i want to do is if the user types in the number "1" into the prompt box, i want it to check the first 15 elements and increase only one of the elements by 1, and if the element has already been increased by 1 then i want it to check the next element and see if its been increased, if the element has been increased then it needs to move on to the next one and check that. If the element is 1, then it can be increased by "1", if the element is 2 then i need it to check the next element. If all elements within the first 15 have increased by 1, it should just alert the user that all slots have been assigned. Is there a way to do this? Thanks for your time
Hi, I'm pulling my hair out to create a simple function! I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions. So far I have this: function QuantityMWh(form) { var formchk = document.forms[0] for (i = 0; i < formchk.elements.length; i++) { if (formchk.elements[1].value == "" && formchk.elements[2].value == "") { alert("Please fill out all fields.") break } } } It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes. What am I doing wrong? Thanks. Hi Folks - I have a form that has an array of input values: <input type="text" name=txtValue[] /> <input type="text" name=txtValue[] /> I do this so I can loop through the values in php... now...that's the easy part... the hard part comes to this: next to each of those boxes is a search button that allows the user to open up a popup window that they can search for an item, and select the item. Once they select the item it should populate that particular input box with the selected item. I can easily do this with a uniquely named input box, but can't seem to figure out how to do it with an array of input boxes... any idea? Hi Guys I am new to javascript programming and I am trying to get elements from one array to another, here is an example of what I am trying to do; Code: oneArray[0] = anotherArray[10]; Essentially, moving the data in index 10 of anotherArray to the index 0 of oneArray. I have tried using a variable as a place holder such as; Code: placeHolder = anotherArray[10]; oneArray[0] = placeHolder; I know i'm doing something idiotic somewhere along the line, I just can't figure out what I need to do. Hi All, Simple newbie question here - I want to initialize an array with "myString.length" elements, and I want every element to be prepopulated with "*" instead of blank. Is there any way of doing this? Code:
var myString = '123456';
var trialVar = new Array[myString.length]
document.write('TEST ' + '<BR><BR>' + trialVar);
(I want every element of trialVar to be "*", I cant just manually add them as myString.length will vary) Any help would be mega appreciated - thank you I'm writing a simple Chess Record keeping app (still ), and i'm having a problem with the Screen.X and Screen.Y variables to compare with the coordinate variables stored in an Array. The project is a little large, so here's the live version (on my website). Though it will only work if you run it from your local disk. http://daomingjin.googlepages.com/ScoreMate.html the zip archive of this is he http://daomingjin.googlepages.com/ScoreMatev1.zip the main JavaScript function file is he http://daomingjin.googlepages.com/Core.js the particular function in question is this: Code: var PieceThere = isPieceHere(ClosestX, ClosestY);
function isPieceHere(x, y)
{
// Test to see if there is an Element at point x,y
for (var i = 0; i < 32; i++)
{
if (PieceLocationXcoord[i] == x)
{
if(PieceLocationYcoord[i] == y)
{
// There is a piece there
var Result = "True";
}
}
}
return Result;
}
i have placed alert() boxes in many places in the code above, and i can tell the following: the function is being activated the coordinates of x and y are able to be accessed inside the function the arrays called PieceLocationYcoord and PieceLocationXcoord both have the values in them that are returned by the ClosestX and ClosestY function however, every time , the function continues to return "Undefined". I have even tried manually setting var Result = "True" inside the last if-then block, and still returns undefined. i have also tried using the alert box inside this function (before the variable return Result; is called) and still get undefined as the message from the alert box. |
