Setting Variable Equal To Php Variable By Passing A Parameter?
Aug 12, 2011
Code:I am having problems with the following. I am wanting to hide <tr> in my table (employees) and only show employees that are in the selected department (selected via dropdown box).I need to set a javascript array to a php array. I am looping and assigning the array and am wanting to pass a javascript variable as the index in php array. I have marked my problem lines in red. Thanx for any help.
<script type="text/javascript" >
function display_elements()
{
var departments = new Array;
I've been staring at this same problem for over a week now. I've worked around it as best as i can but i think it's time to ask someone else for input.
I'm trying to pass a value thru an ajax parameter.. that's all. it SHOULD be easy in theory.
What i want to do is create a jscript variable then pass that variable as the value for a parameter.
Php then converts that value to something it can use to finish the rest of my code.
As i said it's hindering my webpage progress and i would like to get it fixed soon.
I'm more of an actionscript person but got roped into an html/javascript job.What I need to do, and it shouldn't be that difficult is this:page1.html - there is a yellow button and a red button - if the user clicks on the yellow button I want to set a cookie with the value "yel" then load the next page - if they click the red button set that cookie with the value "red"page2.html - 'onload' i want to read that cookie and load up the main image to match, something like this maybe?... document.mainimage.src='img/main_' + variable + '.png'so that the path would be for example 'img/main_red.png'f you think this would be easier sending that variable in the URL instead of as a cookie please explain. I'm having a very hard time searching for tutorials that are any good and that do exactly this kind of thing.
I'll get it out their early, I am somewhat of a javascript novice.
Here is the code I am working with:
<script type="application/javascript"> $(document).ready(function() { var numitems = $("#foo6 > li").length; var secondstartpoint = numitems -3;
[Code]....
As you can probably see I am trying to set the start point of a jquery carousel to equal a variable that I have created. You can see I have tried " start: secondstartpoint", but this isn't working. I think possibly because the way the plugin is formatted so that the "start" option can only equal a number.
Find a solution to this... I am trying to get a page to load into a div, but only if a database variable is equal to 1, if the variable is not equal to 1, it should check back every 5 seconds. Once the page is loaded into the div, it should stop checking. Also when the page that was loaded into the div is closed, everything starts over again.
I have a JSON array data.cells that I need to iterate through to get the values out of and put the values into an onclick event listener.
Right now the variable name data.cells[i].letter is being based through the buildString function for each cell in my board, instead of the value of the variable. Same goes for the x and y variables.
Basically I have a javascript variable... var caption... I need to get that into php so I can run a mysql_query... I then need to get the result back in to javascript...I can do the last bit... In fact I have it almost working except the first bit... Here's the code...
function showpic (args) { var argsarray =args.split ("_SPLIT_"); var imgurl =argsarray[0]; var caption =argsarray[1];
[code]....
The end result needs to be this... I need to lookup if the value in var caption is in the jos_jxzine_articles database... Then I need to return the id from the appropriate row as a argument for shadowbox.open...
I have a javascript will a) look for a certain value in a drop down box and b) depending on what value is selected open up a div that includes link that when moused over will pop up with an alert box contain the passed parameter. A couple problems with this, one is I am not as sharp on Javascript as I am on PHP, and two, when I manually place a value into the function parameter, if it's a number it works fine, but if its a string or word, it comes up with an undefined error. why the undefined error is coming up only on strings or words?
Code JavaScript: var cookies="cookies_and_cookies_cookies_cookies" var blah_blah_blah="whatever" function reallycool(cookies){ document.write("whatever you like to do" +cookies); }
what this won't print when I have named the function and have a variable in the parameter and I can't see any errors in the syntax ?
a user goes to a page, selects a value from a select box then clicks a link to run a report using that hidden variable as a parameter. I am attempting to place the value in the URL to pass it. I'm sure the javascript is working, and maybe it's the HTML I've messed up - not sure.Here is the javascript (the alert does return the correct value):
function OnChangeDay() { //assign the day id to the hidden variable $day x=eval(document.getElementById("day_loc_id_select").value)
[code]....
And here is the HTML that should send the value, but I get day= (nothing)
<a href='/depts/edoptions/excel_extract.php?ex=2&day=<? echo $test_day ?>'>SLIP Data to Excel</a>
I have found a script that works fine for me but I'd like to make it reusable but I have an issue with that. On the script I have something like
function my_function() { var $container = $('#panel .container'); } and I'd like to pass the id (panel in this case) as a parameter like in the example below:
I have a google map which gives directions in different languages based on a select box selection. Google gives directions in English as a default, and if you make the selection AFTER the directions are displayed, then it changes languages. All good so far.
But if you make the language selection first, it still displays in English and then you have to select your option again. What I'd like is to say be able to choose "Italian" and for the directions to come up in Italian on the first hit.
My test page is here (http:[url]...) - you can click on "to here" or "from here" and enter "alyzia, greece" in the input box to see what I mean. I'll post the relevant bits of code below, too. locale is the variable the API uses for language selection.
var to_htmls = []; var from_htmls = []; var locale;[code]....
Whenever I try to compile a script I wrote, I get the error, "class, interface, or enum expected" and it points to a spot in my script that I don't think should create an error. code...
I'm trying set an option with a certain value to selected. I'm using this: $('#mySelect option[value="' + myValue + '"]').attr('selected', 'selected'); This has worked in another piece of code I wrote, but now IE 6 and 8 are throwing an error (in the debug bar). It's something similar to this: "The selected attribute couldn't be set. Unknown error." Anyone ever experienced something similar?
Have the Javascript function below which takes the name of an input on the form passed as a variable so that 1 function can check many inputs as I have up to 3 fields per form that can accept this data range.
function contact_number_check(formObj,field) { var obj = document.forms[formObj]; var regExp = /^([0-9 ])+$/; alert(field);
What I need to do, and it shouldn't be that difficult is this:page1.html - there is a yellow button and a red button - if the user clicks on the yellow button I want to set a cookie with the value "yel" then load the next page - if they click the red button set that cookie with the value "red"page2.html - 'onload' i want to read that cookie and load up the main image to match, something like this maybe?...
document.mainimage.src='img/main_' + variable + '.png'so that the path would be for example 'img/main_red.png'Any help please? Preferably javascript only and as simple as possible. If you think this would be easier sending that variable in the URL instead of as a cookie.
I think this is what I am trying to do, I am pretty new to javascript so I'm not sure... but here is my question... I got this function below.
function getProductInfo(id) { var sku = window.document.InvoiceForm.Item0Sku.value; alert(sku); }
when I use the 0 I get the right value back, however whenever I try to pass it the id variable with a value of '0' I can't seem to compose the concatenation correct in order to recieve the correct value.I either recieve errors or the whole window.document.InvoiceForm.Item0Sku.value string back in the alert, what am I doing wrong?
