How Do I Get Dynamic Arrays As Values For The Javascript?
Jan 9, 2007
I know very little javascript and need to use it to pt a banner across a page, where it is pulling from values a customer puts in the backend.Here is the javascript: Code:
I have a form that has been dynamically created from PHP. It is basically a calculator and the number of form elements as well as names of the elements can vary greatly.
I basically want to add a button that will open a new browser window with the form info being passed to it. Basically it will create a quotation for the customer that is suitable for printing.
The only way I know to do the popup window is with javascript (unless php can do it). I know how to access form elements with javascript if the form element exists, but given most of the elements may change, I do not know how to access them.
See attached mock-up of my site's order table... if I can figure out how to upload an image... [IMG] The user is allowed to change the quantity of items (input fields in the green box) to select which suppliers to order from, and based on this the values in the red boxes should be calculated. It should be a simple problem of multiplying quantities by prices and summing across suppliers for each product... but I want to do it in javascript without reloading the page : )
All values are taken from my database and stored in a php associative array - which seems to be the main complicating factor as it's quite a deep one. $products[13789]['sellers'][3]['products_price'] = 16.99 How would you guys tackle this? Are there any examples/tutorials out there you can point me to?
i need some help with an assignment. the program needs to display a list of flights from options selected from drop down menus. i have written the code to display all flights, now i need to write the code to include the options such as destination and airline. here is the whole of the code.
<script language="Javascript"> <!-- function checkFields(){ var errormsg = ""; if (document.this_form.this_select.value == "") { var errormsg = errormsg + "Please Select an Value.
This may be more of a Java question, but I feel that JavaScript experts may be more qualified to help me find a solution.
In short: is it possible to call a Java method from JavaScript, passing as an argument a JavaScript array (in my case, an array of doubles)?
Supposing I have array x containing only doubles, I have tried: document.MyApplet.myMethod(x);
But the method only ever seems to receive "null" as an argument. Conversely, if I try this with a String, or a single character, or almost anything else, there isn't a problem. Any ideas?
I'm having an array dynamically fetched from the database using php, in result, I'm getting a check box, with their corresponding value.
I wanted to make a javascript function so that if I uncheck a checkbox, corresponding value disappears.
Before going to the looping, I was trying to do a simple check - like this -
function checkOtherValues() { if (document.myform.checkmember[0].checked==false) { document.myform.checkvalue[0].value=""; } } I thought this should work, but I'm getting the following error -
document.myform.checkmember.0 is null or not an object For the form, it's set in this way -
Basically the order form works this way (see attached image to clarify) - the user clicks on one table to select the price wanted of the product and this value appears in the second right hand table automatically.
So far, so good.
But I am trying to get a subtotal value that adds the cost of the products automatically too.
At the moment I am using this function to set the price in the second table:
function set_price(val, count) { var g = <?=count?>; var eachValue = document.getElementById("price" + g); eachValue.innerHTML = "£"+val;
I'm trying to pass multiple dynamic values between a slaveform and a masterform. The problem I'm having is on the slaveform I loop through multiple records and want two values depending on the row they select....
i am inserting values using AJAX.for single record its working fine. but i want to use five text boxes for the same function and for each text box i am calling same function.but now value are not passing properly..whetever passing first time only that value is going into database twice or how many times i have entered the values .so i want my function should work dynamically.with each add button should take value for that text box only.
here is my code
Code JavaScript: // Optional: Show a waiting message in the layer with ID login_response document.getElementById('insert_response').innerHTML = "Adding..." // Required: verify that all fileds is not empty. Use encodeURI() to solve some issues about character encoding.
HTML Code: function makeForm(name) { mypara=document.getElementById("paraID"); myform=document.createElement("form"); myselect = document.createElement("input");
[Code].....
I am creating a form dynamically using javascript.The form is created successfully. After creating the form before submitting the form i would like to make some check points before submission.so while creating the form i am adding the event on submit=call function for validation .THe function is called successfully but i am unable to retreive the form values in the validation script
I'm a complete beginner to JS and have been playing around with a few test projects but I am stuck with one particular part.It simply creates a new text box if you press the Add Text Box button, and removes the text box if you press the Remove Text Box button.What I want to do now is add a usable value to each text box (e.g. the first text box will have the value "tb1", the second "tb2" and so on - so that I can post the data to use it further on.
I have a dynamic drop down menuit populates just finei want to populate my table on the same page based on the selection the user makes from the drop down menu with the information from my database.i have no problem accessing my database or with the drop down but im not at all proficient with javascript which is what i keep seeing with the "onchange" function.
I have multiple rows of data in an HTML table. E.g., financial transactions. In each row I have an HTML dropdown SELECT with options (user will select transaction tag). I want the transactionID and selected tagID to pass to an onchange event for that unique row. The transactionID comes through for the unique row of data, but I
i'm trying to build a small script for predicting Worldcup football winners. participants have to predict the teams in both the semi finals and final. a select menu with all participating countries will be given for 2 semi finals. suppose if a persons selects Argentina and Brazil for Semi 1, then the values of Final select menu should be Argentina and Brazil. Similarly for Semi 2, if Denmark and Italy selected, then the select menu for final2 should be Denmark and Italy.
my html (with only a few no. of countries is below:
[CODE] <b>Semi Final 1:</b><select id="semi11" class="select menufield_101" name="semi11" onchange="ChangeValue(this);"> <option value="empty">Select a SemiFinalist</option> <option value="Algeria">Algeria</option>
Can I control the src attribute of a header <script> tag so that it loads a different script file depending on the value of a variable?
I have a javascript file that currently holds the variables for several countries and weihgts too much for a single file. I estimate that only 2-3kb of the 40+ that it now holds are used at any given point depending on the user's chosen country.
Now, I can split the file into several smaller files to reduce loading time but only if I have a way of dynamically loading the different files.
