JavaScript - Javascript + Checkboxlist Question
Hi,
I have a parent form and a child form.. I have a checkboxlist in my child form. Users can select multiple values from checkbox list and on clicking button i want to pass selected values to parent form. Below is my code which works fine for passing value from child form to parent form (for the value entered in textbox) by clicking on button in child form textbox value is passed to parent form and child form closes, but how to pass multiple selected values from child to parent form. child Form: Code: Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
Dim scr As String = "<script language=javascript> function Done() { var lName=document.getElementById('txt_division').value; var ret= new Array(lName); window.opener.update(ret); window.close();}</script>"
Page.RegisterClientScriptBlock("done", scr)
End Sub
Thanks to help with code / refer articles. Similar TutorialsI am a newbie with a newbie question =) I recently took an exam type thing using my Firefox browser (v3.5.3). I still have my browser window open that I used, and when I press the back button on the browser I get a message "To display this page, Firefox must send information that will repeat any action ..." Is there any way (either disk or memory cache) to reload the pages with out having to resend the data, OR is there any way (hex editor) to view the exam (forms) questions?? Just curious, Thanks I have an application that has a menu - one of the choices on that menu is "Contacts" - This menu is controlled by css - I've written a script that will modify the css style setting for "display" and "zindex" for the rule that controls the pull down for contacts - this worked for hover, but I am now trying to change to a click event - I successfully change the rule, but the menu doesn't display - not sure if I'm returning incorrectly form the javascript function or what - here's a code snippet: CSS: Code: .primaryNav .subMenu {
background-color: #B0967E;
position: absolute;
width: 300px;
left: 600px; /* 823px - 300px - 20 px + 97px */
padding: 10px;
display: none;
color: #fff;
font-size: 90%;
}
Javascript: Code: <script type="text/javascript">
function SetDisplayCSS()
{
var mysheet=document.styleSheets[0];
var myrules=mysheet.cssRules? mysheet.cssRules[0].styleSheet.cssRules: mysheet.imports[0].rules;
for (i=0; i<myrules.length; i++){
if(myrules[i].selectorText.toLowerCase()==".primarynav .submenu"){ //find "a:hover" rule
targetrule=myrules[i];
alert("Rule is found");
break;
}
}
targetrule.style.display = "block";
targetrule.style.zindex = "10";
alert(targetrule.selectorText);
alert(targetrule.style.backgroundColor);
alert(targetrule.style.position);
alert(targetrule.style.width);
alert(targetrule.style.left);
alert(targetrule.style.padding);
alert(targetrule.style.display);
alert(targetrule.style.color);
alert(targetrule.style.fontSize);
alert(targetrule.style.zindex);
return true;
}
</script>
html Code (names have been changed to protect the innocent) - note the onclick event handler for the contacts menu option. Code: <li class="pn test"><a href="#" onclick="return SetDisplayCSS();" name="contacts">Contacts</a>
<div class="subMenu">
<table width="100%">

Thanks for any help...... HI Guys!! My name is Megan and I am a college student in need of some JavaScript help for my computer science class!! My professor is making us complete some stupid class project for finals and I can't figure it out! He suggested that we may try to find a JavaScript Website to help us if we have trouble figuring out how to write the code. I have looked and looked and can't find out how to fix my code!! We have to write code to make a slot machine .. I have started the code based on what he gave us and have tried my hardest to figure out how to complete it but I do not know how to finish it. I have the images working correctly (kind of.. the second one seems to have problems loading? I dunno what I did to mess that up) and the counter working, but I need to make it add 13 credits when all 3 images are the same. I added code that I thought would work but it's not for some reason that I can't figure out. It should also pop up an alert screen when all 3 are correct and you win. I guess this would have to be including with the if statement and something like alert('You win 12 credits!!!') Lastly I need to add code that prevents the person from playing when the credit line is 0 (so you can't get - credits!) and I have no idea how to do this. Any help would be greatly appreciated!

I have a question about Javascript. Hello. I need help with JavaScript enabled. My job so that I can automatically send button to be pushed faster. I use google chrome. For example; Automatically have form filling add-ons. (Autofill), but only to fill the send button will not print. How can I do this automatically? Button codes; <input type='submit' name='post_shout' value='Shout' class='button' /> Google Chrome address bar: javascript: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx what I need to write here? Can I do it after 1-2 seconds and fill out? Many thanks in advance. (My English is poor) So erm. Hello there. I fail at javascript, and yet, I'm trying it. Anyways, I'm working on this thing. It's an extension for google chrome very similar to firefox plugins and so on. I'm making an extension so that, when installed, it changes the look of facebook completely. I have successfully changed the colors. However, I am having some trouble getting my javascript to change images. If anybody out there has some insight on what I'm doing wrong, I am glad to accept any kind of help that anyone is willing to give me, lol. What I've done so far: I have to change the facebook logo (what I'm trying to do now) and then change the links, and very few more things, and I'm done. Problem: I can't figure out how to change the image. I can change the background color, as you saw earlier. I just need a code to change the image. The CSS behind it is: Code: #pageLogo a{background:#3b5998 url(/rsrc.php/z8S5R/hash/ez3x5cuc.png) no-repeat -21px 0;display:block;position:absolute;height:31px;left:-6px;width:103px;top:10px}
and the HTML implementing it is: Code: <h1 id="pageLogo"><a href="http://www.facebook.com/?ref=logo" title="Home" accesskey="1"></a></h1> and my structure of javascript is: Code: for(i=0;i<=document.getElementsByTagName("div").length;i++)
{
if(document.getElementsByTagName("div")[i].id != null)
{
if((document.getElementsByTagName("div")[i].id=="blueBar"))
{
document.getElementsByTagName("div")[i].style.backgroundColor='#B22222';
}
if(( document.getElementsByTagName("div")[i].id == "headNavOut"))
{
document.getElementsByTagName("div")[i].style.backgroundColor='#8B0000';
}
}
}
});
I appreciate any help anyone's willing to give. I think this is a pretty easy to fix error made by a newb ( me. Can anyone tell me why the call to "this.slideNext() " in the code below does not work. Apparently "this.slideNext() " is not a function? Code: function ScoopAnimation(_path, _start, _end, _delay){
this.start = _start
this.end = _end;
this.delay = _delay;
this.path = _path
this.currentFrame = _start;
this.slideNext() = function (){
this.currentFrame ++;
console.log(' next this.currentFrame : ' +this.currentFrame );
}
this.start= function ()
{
console.log('next this.start() : ' +this.currentFrame );
//THE NEXT LINE CAUSES THE ERROR!
this.slideNext()
}
this.start();
}
Hey Guys, I was creating an image map with rollover images. I was just wondering if I could add a fade effect to the transition. The underarms is the only rollover that works at the moment. Please check the source code for the code because it's too long to post here. http://wedezign.com/chris/ I'm not really looking for someone to fix/answer this for me, but maybe give me a hit in the right direction. I need to fix this while loop to run correctly, but has errors in the code. This code is supposed to fill an array with numbers 1 through 100 and then print them. Here is the code: <script type="text/javascript"> /* <![CDATA[ */ var count = 0; var numbers = new Array(100); while (count < 100) { numbers[count] = count; ++count; } while (count < 100 ) { document.write(numbers[count]); ++count; } /* ]]> */ </script> What i am most confused about is this part of the code numbers[count] i don't understand what is going on there. Sorry i am very new to this. Any ideas would be appreciated thank you. I'm trying to figure out this question that was assigned to me, as I haven't done alot on javascript before but I've tried to get most of this, I'm just not sure if this is correct. If anybody could help it would be greatly appreciated. The question is as follows: You are provided with a string array called country that contains the name of every country that the Ski Club visits. For example one element of this array might be as follows: country[0] = "Austria" Another array called villages contains strings with information on village names and altitude in a particular country. For example: villages[0] = "Austria:Seefield 850m*"; Write a JavaScript function snowReport(countryIndex) that will use the arrays provided to write a report of all villages that include a given country. The function will be passed an integer representing the index of an element of the country array. A match is found if the country appears in a string (Hint use appropriate JavaScript function to evaluate if a country name is contained in a village string.) All matching villages should be displayed. Output should be displayed in the villages div element you defined in part (a). Output is shown for a search for Austria in Figure 1b. <script type="text/javascript"> function makeArray() { var country = new Array(5); country[0] = "Austria"; country[1] = "Canada"; country[2] = "France"; country[3] = "Germany"; country[4] = "Switzerland"; return country; var villages = new Array(2); villages[0] = "Austria:Seefield 850m*"; villages[1] = "Austria:Ellam 100m"; return villages; } function snowReport(countryIndex){ var string = ""; for (var i = 0; i < countryIndex.length; i++){ str += countryIndex[i] + " "; } return str; } </script> </head> <body> <script> var x = makeArray(); document.write(snowReport(x)); </script> </body> </html> Many thanks! Hi, I am just beginning out with Javascript and trying to complete a simple login page. Clicking on the Login button should bring up a message 'Access authorised' or 'Access denied' in the 'output' div of the page. Unfortunately only 'Access Denied' displays, even if the password entered is correct. There are no messages displayed in the Error Console. Any advice greatly appreciated! Code: <html>

I was going through an article on JavaScript objects on "http://www.howtocreate.co.uk/tutorials/javascript/javascriptobject" and there I read Quote: Intrinsic objects - variable types with constructors. * Array * Boolean * Date * Function * Image * Number * Object * Option * Regular Expression * String does it mean that, whenever I want to use any of these objects, I have to create it using new and only then I can use its properties or methods ? 1) There are other objects like document, history, location, navigator, parent and screen. If objects which need to be created using constructor are called intrinsic objects , then what are other objects which can be used without constructor are called as ? Array, Boolean, Image, Date etc all start with capital letter. While document, history, navigator etc start with lower case letter. Why is that ? Is there any difference between objects that start with upper case and those start with lower case ? Are they known by different names ? Thanks I'm trying to implement a registration form (which I made), but then after pressing submit button I would like to display on the main page using javascript the information I have entered. I'm really weak with javascript, so if some on could point me in the right direction I would appreciate it. (ps. This shouldn't be printed in a alert window) I was wondering if it was possible to get java to display images that have the same name but diff numbers like: Soccer*** Displays; Soccer001 Soccer002 Soccer003 Soccer004 .... So on and so forth. Sorry the question isn't worded well lol Hello guys, Im new to Javascript,please help me ya in my php code, I retrieve a ID value and assign to variable like below PHP Code: $id = $gettingdata['id']; and I want this id to be include together with javascript "insertsubcat" function like below Code: <a href="javascript:insertsubcat('.$ID.');"/>Click to insert this data</a>
in the javascript page, I dont know how to call back the id value and i try like code below but it doesnt work Code: function insertsubcat(data) {

Any idea? Thanks Azhan Malaysia I currently have a JavaScript function that works great except for what I am about to explain and wish that i can get it worked out by utilizing someones help in this forum. So, Here goes. I have 2 list boxes one that has a list of options and one empty. when I click the button between the two It places the values into the other box and vice versa which currently works fine. The thing is when I click the submit button to store that info from the list box to the empty box in a DB it does not record the value's as if the box was empty after I have already selected from the list. is there anyone that can help me in figuring this thing out, I would greatly appreciate it. Here is my code: JavaScript Code: <script language="javascript">
function validate_list()
{
if ( document.theForm.ToLB.value == "" )
{
alert ( "Please select header column from the list box. " );
return false;
}else
return true;
}

{
var arrFrom = new Array(); var arrTo = new Array();
var arrLU = new Array();
var i;
for (i = 0; i < tbTo.options.length; i++)
{
arrLU[tbTo.options[i].text] = tbTo.options[i].value;
arrTo[i] = tbTo.options[i].text;
}
var fLength = 0;
var tLength = arrTo.length;

(For that matter, why in the world do you need or want the product( ) function???) Hey guys, I've got a question about this array in my code. I have my array at a size of 20 and all of the elements are initialized to 5. What i want to do is when the user types in the word "dog" i want to increase one of the first 10 elements in my array by 1, increasing it from 5 to 6. How would you do such a thing?
Code: document.cookie = "score=400";
var x = document.cookie ;
alert("Time Up");
window.location.href = "main.php?option=insert_result&result=" + x;
In main.php I have a code that will save data on database. My question is why is that it saved something like score=200; PHPSESSID=m5v9qp5c9trcmfi9mso91b7nh5. All I want is 200 to be saved |
