My client wants to upload multiple files to the server using the FILE type input of the form. Their requirement says that once they click the browse button of the FILE INPUT type , besides file browsing window another FILE FIELD is added at the bottom of this one. and when the user clicks the browse button of second, it adds another until the user clicks the UPLOAD button to submit the form.
I dont know it is possible or not ???? if yes then please tell me how.
The alternate way is to give drop down menu with number and when the USER chooses certain number then ..that amount of FILE FORM FIELDS will be added. i.e if user chooses 3 then three file fields are there to upload 3 files at a time.
I have written a script that i am pasting here, but when i choose the drop down menu and select value the FILE FIELDS are shown but the original drop down menu vanishes..
Please review my code and modify it or refer some script to me.
IF The first choice is possible, i mean adding each FILED by browse button click , then tell me its code, other wise modify this code that i am pasting or give me some link to download a premade script. Code:
I'm having some trouble with my dynamically generated form fields.
As you can see I'm generating new form fields, but the problem lies within the grade field. I have it set up now so that when you change the grade the color of the <select> box changes relative to the grade. A-D are green, F is black with white text, Not Taken is just regular white with black text and In Progress is lightly shaded grey.
I want it so that each one can be changed individually, but I can't seem to be able to figure out how to do that. Heck if you change the first one's grade field, that colour follows the rest of the clones.
This is the jQuery I'm using to change the color of the thing.
I want to add rows and columns on click. So, i have a table with columns and rows and I had a add and remove button. So I want the user to be able to add/remove more rows if they have multiple inputs/outputs.So what I want is when the user clicks on add.png, I want another row of Input and Description to appear underneath the current oneHere is my code..
I'm currently looking at data-piping ie making server calls without reloading the page, the server returning some data to a cookie and the calling page using that same data on the page using DHTML. So far so good...
But is it possible to actually use javascript to actually write more javascript onto the page? Or, alternatively, is it possible to dynamically add a call to an external javascript file.
Something like...
document.writeln('<script src="script.js")
The idea being that the server could return functions for the calling page to use, which would be very nice for complex web applications.
If you can do this, what issues do you need to be aware of?
If you can't, are there any ways of achieveing the same things? I'm thinking of things like dynamically adding a scriptlet call to the page in Windows IE, though a more cross-browser solution would be cool.
Might there be a way to add a set of Javascript functions to a display page's existing set of Javascript functions on the fly without reloading the display page, and if so, how?
A couple of approaches I have tried, but without success are:
- A) For an embedded "retriever" IFrame in the display page to retrieve a set of JS functions from the server and then on its "onload" transfer (by innerHTML transference) that set of functions into the parent display page.
- B) Similiar to "A" but to use regular old browser frames - one being the "retriever" and one being the display page.
- C) Using a JS function in the display page to make a http request for a supplementary .js file(s).
Please note: the goal is to retrieve *only* an additional set of Javascript functions from the server, and then add them to an "original" set of functions already loaded into the browser. Meaning, NOT - say - for an IFrame to download from the server *both* the additional set and again the "original" set, which the parent display page could then run directly from the IFrame.
After "A", "B", and "C", I'm at a loss for further ideas.
I have a working contact form with 3 of the fields requiring validation and they work well. I have added extra fields to the form (StatusClass, Project, CameFrom). These 3 fields return fine but I need to validated them. My problem is that the new fields don't show in the behaviours/validate panel even though they are within the form tag.
<script type="text/JavaScript"> <!-- function MM_findObj(n, d) { //v4.01 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
I'm attempting to sum/add up values within 4 different form fields on the fly, but keep getting a result of NaN....not sure what I'm doing wrong....here's my code:
function calculate(totalElement) { for (var i=1,app_pend_end=0;i<5;i++) app_pend_end += what.elements['textField' + i].value - 0;
I'm working on what is currently a simple form, which will include a list of the users friends. However, seeing as everyone's going to have a different number of friends to submit, I'd really like to just have 1 "Friend" field and a button to "Add another friend" next to it.
The idea is that when someone clicks on the "Add Friend" button, another text field will appear (with another Add button), allowing the user to input more contact details.
I think I'm right in saying that I'd need JavaScript to do this, but other than that I really don't have any idea.
Would somebody be able to let me or know? Or post up a link to a relvant tutorial?
i'm trying to make a form in which a user can add additional fields by pressing on a button. At the moment, my code looks like this:
Code: <FORM id = "myform" name = "myform" method = "post" action = "somefile.php"> <table border = "1" name = "datatable" id = "datatable"> some html <tr> <td colspan = "7"><A HREF = "javascript:addElement(datatable);" name = "add" id = "add"> Add another searchfield</A></td></tr>
[Code]...
However already this doesn't work, and refuses to delete anything. The function does load successfully when the link is clicked ( I tested this by adding an alert).
I created a form that contains about 10 form fields and would like to add the option to dynamically add more sets of those 10 fields if a user clicks a word or a button but I need help. I'm a beginner when it comes to JavaScript. This is what I need to generate dynamically.
I need to make a form in which I have to enter upto 20 email addresses. But I want to show only 5 fields first and then an Add More button. Upon pressing the Add More button it should add another field into the form and displayed. I have seen this type of thing on several websites but don't know how to do it.
How can I add more <input type="file" /> -fields by the click of a button? The idea is that the clients should be able to upload a number of files from the same form, but I shouldn't need to know how many fields they need to begin with. Would be good to have an option to remove fields as well.
I am new to the AJAX world and would like to do something simple, but have not found any examples of it. Maybe I am searching the wrong things.I have a simple form.
The site I am working on has a few forms that allow the user to add new form fields (textbox, textarea, etc.) dynamically. I am using a structure smiler to: <form> <label>Name : </label> <input type = "text" / > <label>Age : </label> <input type = "text" /> <span id = "add_field"> Add Field </span> </form>
<script type = "text/javascript"> $(function(){ //create a new field then append it before the add field button $("#add_field").click(function(){ var new_field = " <label>Name : </label> <input type = "text" / >"; new_field+="<label>Age : </label> <input type = "text" />"; $(this).before(new_field); });});
As you can see I create the field using javascript and just insert it before the add field button. However I have seen lots of other sites have a smiler sort of function but they seem to make an ajax call for the field as they use a loading-type animation during the few seconds it takes for the field to be added. My questions are : Which is a better way of doing this type of thing? And why is one better than the other? If it is better to create the field client-side should I change how I am doing it? Instead of creating a string representing html and appending it should I be doing it a different way?
Below is the html and js I have so far to dynamically place form fields on the form when a certain radio button is marked (Fixed hours). Problem is I can't get the fields to go away if the other radio button is marked (Variable hours). Solutions on what code my js needs to remove the fields when the opposite radio button is marked?
I have a form that has 9 pairs of fields on it. I'd like to change this so that there are only two blank pairs of fields displayed. As the user fills out a pair of fields, it adds another pair of blank fields. This way, the user can fill out as many as their heart desires, but those who don't have that much information to provide, aren't confronted with an unnecessarily huge form of blank fields.
I want to do is add the values of seven text fields on a form and pop that value to an eighth field. I thought the code below would work, but I get "NaN" on the sum field.
Code: function addHazWaste() { document.getElementById('HazardousWaste').value = 0; var HazWasteTotal = 0; var HazWaste1 = 0; var HazWaste2 = 0; var HazWaste3 = 0; var HazWaste4 = 0; var HazWaste5 = 0; var HazWaste6 = 0; var HazWaste7 = 0; HazWaste1 = parseInt(document.getElementById('HazardousWasteSentToLandfill').value,10); HazWaste2 = parseInt(document.getElementById('HazardousWasteSentToWasteToEnergy').value,10); HazWaste3 = parseInt(document.getElementById('HazardousWasteIncinerated').value,10); HazWaste4 = parseInt(document.getElementById('HazardousWasteRecycled').value,10); HazWaste5 = parseInt(document.getElementById('HazardousWasteReused').value,10); HazWaste6 = parseInt(document.getElementById('BiohazardousWasteSentToLandfill').value,10); HazWaste7 = parseInt(document.getElementById('BiohazardousWasteIncinerated').value,10); HazWasteTotal = HazWaste1 + HazWaste2 + HazWaste3 + HazWaste4 + HazWaste5 + HazWaste6 + HazWaste7; document.getElementById('HazardousWaste').value = HazWasteTotal; }
If I run a separate function that just sets all form field values to zero (including the first line of this function). The summing works!!! Why won't it work the way I wrote it??? It won't work if I set the default value for the sum field to zero, either...
I have a form with 3 fields that will allow a user to search a database of clients by either name, email, or client id number. However, I would like the user to only be able to put information in one field. It can be done be either deleting the other two fields when the user inputs information into a different field, or by disabling the other two fields when the user enters information in one (and also frees up all fields if the user ends up deleting what they entered).
Below is a start of what I had. Basically, it will disable the fields when I mouse out of them but won't re-enable them when I mouse back in. As you can see, I tried various combinations of events. (My code below also doesnt null out the other fields when the user opts to use a different field than the one they first began to enter info in).
<html> <head> <script type="text/javascript"> function makeDisable($ID){ var x=document.getElementById($ID)
I am trying to assign values to a bunch of form fields. However, I don't want to loop through EVERY field in the form, just a specific subset of fields. The fields I am trying to change are all named similarly myField1, myField2, myField3.So, my thought is that I would like to use a for loop and loop through the appropriate fields by simply incrementing a variable and appending it to the end of the string "myField" in order to change the appropriate field.How can I evaluate "myField + iterator" into a useable reference to change the value of said field?
So, I have a form that, when the user clicks on a link, uses J/S to generate extra form fields for extra information. I can retrieve the value of the dynamically generated fields using $_POST in I.E., but it doesn't work in Firefox (no value is returned). Retrieving values for the static fields is fine in both I.E. and Firefox.
Here's the code - is there a function I'm using that could be replaced with something more friendly to Firefox?:
<script type='text/javascript'> var i = 1; function addArea() { var newArea = addElement();
The link below is a stripped down section of a form.
[url]
The problem I'm having is with altering the names of the fields. I'm trying to add an identifier on the end. "_X_1", "_X_2" after the new sections are added.
NOTES:
Incidentally, "_X_" is a delimiter so the key can be converted into an array on the back end to extract data from it.
I can't alter the "repeater" variable because it would be extremely complicated on the back end.
How do I add form inputs dynamically? I found form wizard plugin, but it could only add one element.
$("#finland").after('<span class="step" id="added_step">New step added in the update steps callback</span>') I needed it to add the same elements as much as possible, how do I do that with the code below?
It works perfectly but I need to add more fields than stated in the post. If I add in another field, only one field gets the increment. The other doesn't. Eg.
Currently, I have a php form with various inputs, and a div where I am embedding an (initially) empty open flash chart object.Right now, I am calling a php file on the submit of the form, which takes the form data, calls a python script to process the form data, and then creates an open flash chart object using the data the python script returns.There are a few problems with this:
1. When the submit on the form is called, it goes to a different page where the chart is displayed, when I would really just like to update the contents of the chart div where I initially embedded the empty chart.
2. The processing of the form in the python code can take some time, so what I would really like is to have the chart "check" the output of the python script periodically and update the chart each time, adding the new data points to the old ones.
I know I can do all of these things with javascript and Ajax, I just can't seem to find any tutorials or examples that are exactly what I am looking for.
I am currently working on a site as part of a student work term. One of the features of this site is the ability to upload a resume. The resume can have a arbitrary number of "work experiences". I have set up a form and want the user to be able to add new input elements with a click of a button. Here is a very pared down(for simplicity) version of the form:
