JavaScript - Add The Values Of Latitude And Longitude Into The Listboxes

Hello, I am new here, and I will probably break some of the forum rules on accident and I apologize ahead of time, but please go easy on me. I have a problem with a question in a Javascript class I am taking currently. The book explains how to detect the smallest values the user inputs but does not explain how to detect already declared variables that have values in them and how to detect which of these declared variables has the smallest number. For example:

Code:

double aA = 3.7;
double aB = 5.8;
double aC = 1.9;
double aD = 7.2;
double aMin;   //  this is the variable I want the program to detect and stick 
               //  the smallest variable into.

I want the code to detect the variable containing the smallest number and it has to be able to detect negative numbers as well.

I am completely lost on how to do this! Any help would be appreciated!

Thank you!

Hi to all,

Sorry to ak this question it may be easy but i didn't got the solution on net please provide the proper answer.

My question is : I am defining hyperlink in struts as
<a href= Javascript:formSubmit(<bean:write name="AA" property="aa">','<bean:write name="BB" property="bb">)

defining function as

function formSubmit(Aa,Bb)
{
document.forms[0].action="/accesingpage.do?method=create&AA=+Aa"

----> in above statement how to pass the second parameter(i.e Bb)....I tried different ways but giving syntax error.

please post the ans as soon as possible

OK, so a bit of an issue...

I've done a navigation, that works just wonderfully. There are three dropdowns in the top rown, and one down below. The three on the top populate the one below it. All works fine until.... *dum dum dah dummmm*

I wanted to make the bottom box invisible until one of the top onse were selected.

The nav script goes as follows:

Code:

var cacheobj=document.dynamiccombo.stage2

function populate(x){
for (m=cacheobj.options.length-1;m>0;m--)
cacheobj.options[m]=null
selectedarray=eval(x)
for (i=0;i<selectedarray.length;i++)
cacheobj.options[i]=new Option(selectedarray[i].text,selectedarray[i].value)
cacheobj.options[0].selected=true
}



populate(combo1)

Code:

<select name="usstage1" size="1" onchange="showDiv(this.value);window.open(this.options[this.selectedIndex].value,'_top');" >
        <option selected="selected" value="javascript:populate(combo1)">United States</option>
        <option value="javascript:populate(combo2)">Alabama</option>
        <option value="javascript:populate(combo3)">Alaska</option>
        <option value="javascript:populate(combo4)">Arizona</option>
        <option value="javascript:populate(combo5)">Arkansas</option>
        <option value="javascript:populate(combo6)">California</option>
etc...

Which populates the bottom dropdown

Now to hide it, I've done:

Code:

var lastDiv = "";
function showDiv(divName) {
	
	if (lastDiv) {
		document.getElementById(lastDiv).className = "hiddenDiv";
	}
	
	if (divName && document.getElementById(divName)) {
		document.getElementById(divName).className = "visibleDiv";
		lastDiv = divName;
	}
}

And used a

Code:

<div id="menudiv" class="hiddenDiv">

around the lower dropdown, which hides it effectively

then I modded the upper menu

Code:

<select name="usstage1" size="1" onchange=" showDiv(this.value); window.open(this.options[this.selectedIndex].value,'_top')" >

adding what's in red to call the change

Now this is where I'm stuck, how can I get:

Code:

<option value="menudiv;javascript:populate(combo2)">Alabama</option>

the two options in...have tried a couple of different ways and failed horribly eash time...or maybe I'm just going about this completely wrong?

Hello,

I have following javascript that loads a streetmap:


Code:

<script type="text/javascript">
geoportaal_type          = "gemeente";
geoportaal_id            = "blankenberge";
geoportaal_startupmodule = "stratenatlas";
geoportaal_bgcolor       = "FFFFFF";
</script>
<script type="text/javascript" src="http://www.geoportaal.be/syndication/toonportaal.js"></script>

What I want to do is pretty simple: create a little searchbox on my homepage where people can enter their streetname and housenumber and the map loads.
To do this i use following code related to a script:



Code:

<script type="text/javascript">
geoportaal_niscode       = "vilvoorde";
geoportaal_startupmodule = "stratenatlas";
geoportaal_bgcolor       = "FFFFFF";
geoportaal_request_name  = "toonadres";
geoportaal_request_parameters = "straat=Kerkstraat&huisnr=1"; </script> <script src="http://www.geoportaal.be/syndication/toonportaal.js"></script>

Basically the same as mentioned earlier, though some other tags must be used.
How do I create the fields (values) to enter the text and the OK-button to confirm the search?
When users press the OK-button the script must load.

When loading, following values are important:


geoportaal_request_parameters = "straat=Kerkstraat&huisnr=1where straat=VALUE1&huisnr=VALUE2
So:
VALUE1=streetname
VALUE2=housnumber

All I need is the script to take the values entered by the users and to paste these values on the right place (code above).
How do i do this, do i need an onclick-handler for this?

This is html-code for the searchbox but no actions are defined yet:


Code:

<div id=locationsearch>
<table id="form">
<tr><td>Straatnaam:</td><td><form id="form1" name="form1" method="post" action="">
    <label>
      <input type="text" name="straat" id="VALUE1" />
    </label>
  </form></td></tr>
<tr><td>Huisnummer:</td>
<td><form id="form2" name="form2" method="post" action="">
  <label>
      <input type="text" name="huisnr" id="VALUE2" />
    </label>
  </form></td></tr>
<tr><td>&nbsp;</td><td><form id="form3" name="form3" method="post" action="">
  <label>
    <input type="submit" name="toonadres" id="toonadres" value="Lokaliseer" />
  </label>
</form></td></tr>
</table>
</div>

Please advise from A to Z. I'm a novice.

Thank you in advance,

William.

I have 2 combo boxes where you can move the items in combo box 1 to combo box 2. I want to validate that combo box 2 actually has something moved to it. How can I count the items in combo box 2. Combo box 2 will initially have no items in the box on page load. It is up to the user to move the items to combo box 2 and I want to make sure at least 1 item was moved.

hello
I am having a problem to add numbers store in an array.

arrayValues[0][0] = 1;
arrayValues[0][1] = 2;
var col = 0;
var sum;
for ( var row = 0; row < index; i++ )
sum += arrayValues[col][row];


my result is ==> 12 it is defining my sum variable as string. even I try do do this var sum = 0; to define sum as numeric variable. my result was ==>012.

Any idea, this is my first javaScritp code.
Thanks.

Can someone please tell me how I would modify the following function to get it to check if a url variable is present and if so to add it into the string variable for the url.

Code:

function ajaxFunction(pagenum){
	var ajaxRequest;  // The variable that makes Ajax possible!
	
	try{
		// Opera 8.0+, Firefox, Safari
		ajaxRequest = new XMLHttpRequest();
	} catch (e){
		// Internet Explorer Browsers
		try{
			ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e) {
			try{
				ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (e){
				// Something went wrong
				alert("Your browser broke!");
				return false;
			}
		}
	}
	// Create a function that will receive data sent from the server
	ajaxRequest.onreadystatechange = function(){
		if(ajaxRequest.readyState == 4){
			var ajaxDisplay = document.getElementById('ajaxDiv');
			ajaxDisplay.innerHTML = ajaxRequest.responseText;
		}
	}
	var drop_1 = document.getElementById('drop_1').value;
	var model = document.getElementById('model').value;
	var mileage = document.getElementById('mileage').value;
	var colour = document.getElementById('colour').value;
	var age = document.getElementById('age').value;
	var min_price = document.getElementById('min_price').value;
	var max_price = document.getElementById('max_price').value;
	var min_engine_size = document.getElementById('min_engine_size').value;
	var max_engine_size = document.getElementById('max_engine_size').value;
	//var pics = document.getElementById('pics').value;
	if (document.getElementById("pics").checked==true) {
		var photos = "Yes";
	}
	else {
		var photos = "No";
	}
	var keywords = document.getElementById('keywords').value;
	var queryString = "?drop_1=" + drop_1 + "&model=" + model + "&mileage=" + mileage + "&colour=" + colour + "&age=" + age + "&min_price=" + min_price + "&max_price=" + max_price + "&min_engine_size=" + min_engine_size + "&max_engine_size=" + max_engine_size + "&photos=" + photos + "&keywords=" + keywords + "&page=" + pagenum;
	ajaxRequest.open("GET", "filtered.php" + queryString, true);
	ajaxRequest.send(null); 
}

If my url is index.php?make=Apolo then I need to get this added into the var queryString part of the function so that the ajax returns the correct values.

Any help would really be appreciated, I'm fairly new to js.

Hello

Thanks to those people on this Forum who have provided me with help, along with my little knowledge of Javascript I have been able to create the basis of a form for my Skittle League which will allow teams to submit results over the web.

I have one calculation to complete before I look to make the form live and I am hoping someone can provide the final peice of the jigsaw.

The scoresheet can be found at

http://www.stroudskittles.co.uk/test/scorecard.html

The form adds togther the 5 values for each half for each team and places them in a Half Total box below.

The form adds together the two totals for each half for each team then places them in a Total box below

I have been able to add a operation using the onchange event the points are automatically calculated for each half and total, depending on the overall scores, 2 points for a win, 1 for a draw 0 for a loss.

What I'm struggling to do is add the three points totals together to generate the Overall Points for a team and place them in a text box at the top of the scoresheet (marked xxx on the page).

Can anyone suggest the best method to do this.

Also is it possible to combine the sums into one script therefore reduing the overall size.

Your help very much appreciated

Hi all,

I'm using a nifty little form-dependency script (http://www.dynamicdrive.com/dynamici...dependency.htm) that will hide certain form fields depending on the answer to previous fields on the form.

Basically, I can make a field hide/appear for users with JS enabled; for example, if the field "Instrument1" is answered "Oboe" then this new field that I designate will appear:

Code:

<input type="hidden" class="DEPENDS ON Instrument1 BEING Oboe" />

What I really want to do is use JavaScript to manipulate Instruemnt1 do that it will work with Instrument1, Instrument2, Instrument3, all the way through Instrument10. If any one of those 10 "Instrument*" fields are answered "Oboe".

Thanks for reading.

Hi Guys,

Code:

<script type="text/javascript">

Hi There,

I need your help.

I am capable of getting all the field headers in my excel document but am now unable to get their respective field values. Any idea as to what I am doing wrong?

Code:

var book	= excel.Workbooks.Add() 
var sheet	= book.Sheets(1);
  
 //sheet.Range("A2").Value = "Hello World"
 
//WRITE COLUMN HEADERS:
  	sheet.Columns("A:P").ColumnWidth = '15'
	for (var c = 0; c < rs.fields.count; ++c) {
	sheet.Cells(4, c + 1).Value = rs.fields(c).name      
	}

//WRITE FIELD VALUES:
	var row = 1 
	for (var c = 0; c < rs.fields.count) {
    sheet.range('A' + row).value = rs.fields(c).value
    row = row + 1

I sell products on amazon. and ASINs are Amazon Identifiers for products. So If I want to check out my product pages I have to go to "www.amazon.co.uk/dp/ "I have to put an ASIN here" . If I can put everything together in the text box and hit go it should take me to the first page(first ASIN). Here is a sample ASIN B004Z2QORW

I have the code below but I somehow cant get it to work. Please help. I haven't assigned anything to the go button. I will put a list of ASINs in the text area and the iframe should concatenate the value from a row to the hardcoded URL and when I click next it should concatenate the value from the next row; when I click previous the value from the previous row.

Code:

<HTML>
<Head>
<H1 align="center">Detail Page Lookup using ASINs</H1>
</head>
<body>
<textarea rows="10" cols="20" value="">
ASINs here
</textarea>
<button id="go">Go</button>
<button id="prev" align="right">Previous</button>
<button id="next" align="right">Next</button>
<br/>
<iframe id="myframe" src="http://www.amazon.co.uk/dp/" height="100%" width="100%">
  <p>Your browser does not support iframes.</p>
</iframe>
<script>var domain='http://www.amazon.co.uk/dp/';

$('#prev, #next').on('click', function(e) {
    var Myval = $('textarea').val().split('\n'),
        now = $('#myframe').attr('src').replace(domain, '');
    if (Myval.indexOf(now)==-1) {
        var src=domain+Myval[0];
    }else{
        var p = Myval.indexOf(now)!==0 ? Myval.indexOf(now)-1 : Myval.length-1,
            n = Myval.indexOf(now)==(Myval.length-1) ? 0 : Myval.indexOf(now)+1,
            src = e.target.id=='next' ? domain+Myval[n] : domain+Myval[p];
    }
    $("#myframe").attr('src', src);
    console.log(src);
});
?
