Getting Variables From Php Into Javascript.	View Content

I am perplexed about this one.
Not sure if php is the best solution or maybe javascript.
( or both.)

I am writing a litle script that will go to my mysql table and take out
20 rows ( from about 10,000 rows ) based on the WHERE statement.

Then I want to step through these 20 rows displaying
just two filds in this fashion:

First, I want to display one field in a "box" ( using divs and css )
then wait for a form input.
Then while keeping the first displayed box and field
display the second field in a similar box a fee lines below.
Wait for a form input
update some data.

Then onto the next row.

If I use javascript then I could keep all the processing on one page and not have
to have server refreshes.

But how do I get these those array elements from
$row['field1'] and $row['field2'] into javascript vars ?

Is this the best way to do this ?

Or would php and having a couple of extra trips to the server
for form processing be better ?

Thanks for any input.

Hi,

I have the following code snippet:
test.html
======
<script language="javascript" type="text/javascript">
var testVariable = "test";
</script>
<script language="javascript" type="text/javascript" src="test.js">
</script>

test.js

var testVariable = window.top.testVariable;

In firefox, I'm able to access testvariable defined within test.html in test.js.

But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html.

Can any one please let me know how i can make it work in chrome?. Am i missing something here?.

Javascript Config File + Javascript Class/functions File - Variables Not Found

Similar Tutorials

View Content

All --

I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game.

I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so:

<script type="text/javascript" src="gameSetting.js" ></script>
<script type="text/javascript" src="gameLibrary.js" ></script>

In gameSetting.js I have:

$(document).ready(function()
{
// call some functions / classes in gameLibrary.js
}

in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined.

I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load...

$.getScript("gameLibrary.js");

However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem.

My options a

1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense.

2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers).

jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work.

Help appreciated.

Hi,

I'm looking to use the document function in javascript to change the TYPE of an INPUT.

However I want to change the TYPE of the INPUT according to a variable passed to the javascript button, so i use:

document.formname.inputname.value="newvalue";

I want to be able to change what inputname is depending on what is passed to the function, but right now firefox is telling me that it's undefined.

Is there any way I can do this?

Hi all,

I'm a javascript newbie and having some trouble with what I imagine it s a very basic issue!

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value.

I am setting it within this function:

Code:

function show_video1(){
	document.getElementById('video1').style.display="block";
	var video1Name = "Education World News (Part 1)";
	document.getElementById('video2').style.display="none";
	document.getElementById('video3').style.display="none";
	document.getElementById('video4').style.display="none";
	document.getElementById('video5').style.display="none";
	document.getElementById('video6').style.display="none";
	document.getElementById('video7').style.display="none";
	document.getElementById('video8').style.display="none";
	document.getElementById('video9').style.display="none";
	document.getElementById('video10').style.display="none";
	document.getElementById('video11').style.display="none";
}

and trying to call it later on with this:

Code:

<script type="text/javascript">document.write(video1Name)</script>

It might be worth noting that each one of my 11 videos will hace a different name.

Can anyone help out a newbie?

Many thanks,

Boolean Variables In Javascript?

Similar Tutorials

View Content

I am about to translate some C++ code to JavaScript.
In C++, it is straightforward to declare and use a Boolean variable; all I do is swap it between true and false and back again as needed.
For example,
Code:

// C++ Code
. . .
bool na = 1;
. . .
na = !na;

. . .

I am wondering if JavaScript offers boolean variables. As far as I know, it does not, but I thought I would confirm by asking around.

At the moment, I am planning to code the comparable block in Javascript using an "if" statement or a ternary operation.
For example,
Code:

JavaScript Code
. . .
var na = 1;

// Option 1
if (na) na = 0;
else na = 1;

// Option 2
na = ((na) ? 0 : 1);
. . .

Is one of these options recommended as the best way to simulate a boolean variable and operation? (I would like the fastest-executing code possible.) Or is there another--better--way to do it?

All advice and recommendations appreciated.
Thank-you in advance.

Passing Php Variables To Javascript

Similar Tutorials

View Content

Hi,

I hope someone can help me!

I have a list of buttons, each with a different id which is taken from the ids of these values from the database. When I click one of the buttons it shows the items that correspond to this id in the database. Therefore, when different buttons are clicked the display changes to match the objects relating to this particular button.
When a button is clicked, this shows various other objects which I can then select (using a checkbox). When a checkbox is clicked, a Javascript function is called to change the html text next to the appropriate button.
However, I can't get this to work as I need to pass the id of the button, and the html span, to the Javascript in order to change the correct text.

Here is my Javascript :

Code:

    function questionnum(checkbox) {

        if(checkbox.checked) {
        
        
		 	
            var qdesNumElement = document.getElementById('<?php echo $q;?>');
          
            var qdesNum = qdesNumElement.innerHTML;
            qdesNumElement.innerHTML = ++qdesNum;
            

    }

This code only gets the last button.

Please help.

Inserting Php Variables Using Javascript

Similar Tutorials

Hi,

I am using javascript to collect hidden form elements and then send the values to a php page, without reloading or changing the page. Basically i have a list of job vacancies, with just an apply button, when a person clicks on the apply button, the form collects some information from their account and sends it using the javascript code.

Now this works fine, except for if somebody then clicks on the second job it sends the information from the first form again. And it seems to remember the information.

What i am trying to find out is it possible to have multiple forms on one page which once submitted send variables to javascript which then send them to a php but clear themselves so that it doesn't remember the previous values.

Here is the code for the form:

Code:

<form id="submit" method="post">
                            <fieldset>
                       <input type="hidden" name="usern" id="usern" value="php variable" />
                       <input type="hidden" name="joborder_id"  id ="joborder_id" value="php variable" />
                       <input type="hidden" name="site_id"  id ="site_id" value="php variable" />
                       <button class="button positive">Apply For This Job </button>
                       </fieldset>
                       </form>
                       <div class="success" style="display: none;">Your Application has been sent.</div>
                              &nbsp;
                            </form>

And the Javascript code is he

Code:

$(document).ready(function(){
	$("form#submit").submit(function() {
	// we want to store the values from the form input box, then send via ajax below
	var usern     = $('#usern').attr('value');
	var joborder_id    = $('#joborder_id').attr('value');
	var site_id    = $('#site_id').attr('value');
		$.ajax({
			type: "POST",
			url: "apply.php",
			data: "usern="+ usern +"& joborder_id="+ joborder_id +"& site_id="+ site_id,
			success: function(){
				$('form#submit').hide(function(){$('div.success').fadeIn();});

			}
		});
	return false;
	});
});

Any ideas or suggestions would be appreciated,

Thanks

Javascript Switch Statements And Variables

Similar Tutorials

View Content

Hi, I believe this question has been asked by someone else before. However, it seems that the problem wasn't resolved. I'm having some trouble with the Switch Statements. My program runs without it so I know that the problem is here. I believe the logic is sound so it may be due to incorrect syntax.

I will appreciate if someone could take a look at my code below and guide me in the right direction.

Thank you.

The purpose of this function is to create bars, and the length of the bars is determined by the value of the "percent" variable (which is working fine) in the For loop after the Switch statements. The variable, "partyType" contains any of the text strings, such as "I", "D", etc.

Code:

function createBar(partyType,percent){
var barText;

switch(partyType){
case "D": 
barText="<td class='dem'></td>";
break;
case "R":
barText="<td class='rep'></td>";
break;
case "I":
barText="<td class='ind'></td>";
break;
case "G":
barText="<td class='green'></td>";
break;
case "L":
barText="<td class='lib'></td>";
break;
default: document.write("hi");
}

for(var i=1; i<percent; i++){
document.write(barText);
}
}
}

Hi,
I am trying to print a hard copy from a database using php and javascript.

this is my console display:

Uni ID  	                                  Name
i1111111 ................................. Maeve O'Neill

and the javascript is:

var display_setting="toolbar=yes,location=no,directories=yes,menubar=yes,";
display_setting+="scrollbars=yes,width=750, height=600, left=100, top=25";

Reference Variables In Arrays In Javascript

Sql Query, Json_encode, And Javascript Variables

I have an array from a sql query that I need to use as variables in a javascript function. I have created the array, used JSON_ENCODE to bring the information into javascript, and so far everything works correctly.

I am trying to use a list menu in html to select one on the indexes of the array so I can pass the information from the index to a javascript function.

Here is the javascript function:
Code:

function selectTable(item_id)
{
var media = eval(<? echo json_encode($paperTable); ?>);
var click_k_1=media[item_id]["click_k_1"];
var click_k_501=media[item_id]["click_k_501"];
var click_c_1=media[item_id]["click_c_1"];
var click_c_51=media[item_id["click_c_51"];
var click_c_101=media[item_id]["click_c_101"];
}

Here is the list menu coding:
Code:

<select name="pprSel" size="1" id="pprSel" onChange="selectTable(this.value);" >
<option value="204226">20# Bond</option>
<option value="204788">70# White</option>
<option value="204823">80# White</option>
</select>

Here is the source file results from the browser:
Quote:
function selectTable(item_id)
{
var media = eval({"1":{"item_id":"204226","item_description":"20# Bond","click_k_1":"0.1100","click_k_501":"0.0730","click_c_1":null,"click_c_51":null,"click_c_101":n ull},"2":{"item_id":"204788","item_description":"70# White","click_k_1":"0.1149","click_k_501":"0.0779","click_c_1":"0.8789","click_c_51":"0.5539","click _c_101":"0.3589"},"3":{"item_id":"204823","item_description":"80# White","click_k_1":"0.1591","click_k_501":"0.1221","click_c_1":"0.9231","click_c_51":"0.5981","click _c_101":"0.4031"}});
}
I have tried a couple of different ways to pass one of the variables to a text field on the html form as an error check, with no success:
Code:

document.quote.data.value=media[item_id]["click_k_1"];
document.quote.data.value=click_k_1;

The text field on the html form is id='data', the form is id='quote'.

the only thing I can think of for the reason I am not getting anything in my text field is that my variable is not getting set up properly.

Can anyone help? TIA

Looking For Help With Photoshop Javascript (changing Variables))

Similar Tutorials

View Content

Hi,

I'm very new to using javascript to program Photoshop, and was looking for some help with changing the variables in an action.

The basic end result I'm looking for (in laymens terms) is:

Set variables
Perform action
Change variables (iteratively, ie a=a+1)
Repeat until condition met (ie, after 100 iterations, the script would end).

I used a script that converts Photoshop actions to Javascript, so I have this as a base:

Code:

 function step1(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    desc1.putInteger(cTID('0001'),  215 );
    desc1.putInteger(cTID('0002'),  172 );
etc etc (goes through many other variables)
    executeAction(sTID('Flaming Pear'), desc1,

I've put the properties that would need to become variables in red. I have edited out a bunch of lines in this post as these seem to be the significant ones in terms of what I need to do (obviously keeping them in the script itself!).

Other than that I think that's all I need to know for now - just that little thing would enhance my workflow no end.

Also, I'm a graphic designer so if anyone would be interested in doing some skillshare or work swap - I'd be happy to provide help and service with graphics in exchange for small tidbits about javascript.
