Dynamic Form Creation - Ability To Enter Into Text Field
Dec 6, 2010
A while back, I an working on dynamic form creation. I wanted a user to be able to enter into a text field how many designs he or she would like, then, based on that number, be provided with a pair of text boxes that asked 1) name of design 2) quantity of that particular design. I received this cool way of doing it by user thraddash:
<head>
<script type="text/javascript">
function BuildFormFields($amount){
var
$container = document.getElementById('FormFields'),
$item, $field, $i;
I have a form that allows for dynamic field creation. Basically, you click the + button, and an addition row of fields (2 text fields) are created. The area that is dynamically created is wrapped by a <div id>, within which is, and this might be bad practice so please feel free to mock me , another few nested div id's. It looks something like this:
Code:
Each time you hit the +, it creates a new div id beneath the "Adds" id.
What I'd like to do is see the values of the id's "row_fqdn" and "row_ip". Is there a quick way to access the values of nested id's?
I found a workaround but it seems pretty messy and drawn out, something like this:
because of the security settings in browsers i can't set the default path value of a file upload field in a form. i was wondering if there is a way to have javascript type one in when the page loads?
Is there a way to prevent a form submitting when you press enter on a text field? Some people press enter when they finish typing in a text field out of habit I guess unconcsciously thinking it will take them to the next field. Instead it submits the form and this causes all kinds of problems in my case. Any javascript solution?
Am creating a dynamic text box along with datepicker image.. when I enter newdate into the text box, it simply goes to previous textbox and updating the textfield. How to enter the date into the newly created text box??? And also once I complete the first row data , that row should be disabled.
Currently I have this web database app that I wrote in which I have a page with 3 tables. When I want to enter data into the table I currently select the table name from a drop down list and then have a javascript window open containing a form. The form is processed using php and oracle. The parent window which is the page containing the 3 tables then gets reloaded and, behold you can see a row contaiing the data underneath the choosen table. Have a picture in your mind of my setup?
Ok, what I would like is to try and eliminate the popup window. On each of the table headers I would like to have a button that when clicked, adds a row of input cells, say 6 for example . They should be able to have as many rows as they want. I would also like to add a submit button and a remove row button. And that is it.
From there I can handle the input of the multiple rows with php arrays and array splice to get the indexing I want. That is no problem. I have just never done anything dynamic and have very little javascript experience.
I want to bypass from one input field to other one by <enter> (<return>) key pressing instead of default behaviour (<tab> key pressing).But there was default form action on <enter> keydown event was performed. Remember that <enter> keydown event on form means default "Form submit" action. How to prevent default action, form submission, in time of <enter> keydown event processing?
How to modify following code? I use hotkeys jQuery plugin for key binding to input fields.
$().ready(function(){ $(myInputFieldsSelector).bind('keydown','return',function(evt){ //find next input field in the form MyNextInput MyNextInput.focus().select();
The problem is that FF doesn't put the P in the top left corner of the DIV. Rather it seem to push it down by a line height. Is there some white space sneaking into the DIV? How do I get the P right into the top left corner?
can anybody tell me how you can create a new stylesheet inside a (X)HTML page with JavaScript and Firefox, if the stylesheet is only available as a variable value, like:
var CSSStyle = "rect {fill: lightgrey;} circle {fill: red;} polyline {fill: none; stroke: red; stroke-width: 0.3;} text {font-size: 2.5px;} text.text-x-axis {text-anchor: middle;} text.text-y-axis {text-anchor: end;}"
So far, the only workaround I found, was to link an empty stylesheet to the page
I have reason to want to be able to change a Firefox stylesheet rule dynamically. I have found, doing google searches, sites which tell you how to create stylesheets dynamically or just add and delete rules, but none of these pages procedures have worked in my Firefox. Some have worked in Internet Explorer. Most have claimed to be cross browser. An example of one which I had high hopes would work can be found at this link.. The code they give you near the bottom of that page is posted below with the original background color changed to red and some text to see the background color put in the body of the page. In other words I pretty much just pasted the code found their in the head portion of my HTML page.
Attempting to troubleshoot why this code is not working if I use the old alert message method and put an alert message between the lines "var mysheet=document.styleSheets[0]" and the line "var totalrules=mysheet.cssRules? mysheet.cssRules.length : mysheet.rules.length" the mysheet variable region out as being "object CSSStyleSheet", however if I use the newer step through method with firebug it reads undefined. So I am totally baffled. Code:
There is a while loop to keep adding them but wanted to keep it simple. So right now there are three links that get created. I'm trying to find out the value of these links so I can add things to a shopping cart for the user. I have the following jquery to do this:
This part works fine. However how can I get the href value of this and then once I have it basically split it after the = sign to get the value I'm really looking for?
I just wonder if there is a jquery plugin or something that enable me to create a html pagelayout with drag n drop.
Lets say i have a blank page with a div container, then i have a couple of layout elements that i can drag into that container, like 2 coulmn, 1 column, 3 column.
I hope you understund what i mean. something like sitefinitys template builder but in a light version.[URL]
Am developing MonthlyExpenses Project in which we have to enter details according to that date.
Date [IMG]datepickerimage[/IMG] Description Exptype Price
By clicking add button the dynamic row has to appear. But here , when I enter Date , the newdate is overwriting the previous one. New date is not appearing in new text box.
I have a small number of functions on an object and for every function I wish to make a different function that calls the original where the this can be passed as a parameter. I am making a library and this is a convenience method for people who don't know about call/apply.
Currently (one of) my function looks like this:
function _find(){ return find.apply(arguments[0],Array.prototype.slice.call(arguments,1)); }
However since my functions are in a object I was wondering if I could make a new array dynamically?
var func = {'find':find}, func_new={}; //this is just an example I don't have this part in my code for(var attr in func) func_new[attr] = Function('return '+attr+'.apply(arguments[0],Array.prototype.slice.call(arguments,1));');
I have a task to create tables dynamically, using the javascript DOM. The current method uses a 1px x 1px IFRAME to loop through some data generation stuff, and then call JS functions in the parent window to generate the tables.
The basic idea is to add a table tag, with a thead and tbody, on the main parent page, that has display:none set. This then becomes display:block when there are rows to show. The rows themselves are added directly to the visible tbody element using appendChild(). When the results need to be refreshed, the tbody elements are removed, and then added again.
This works well in most browsers, including Opera. However, Mac IE always freezes when trying to generate the table, even for the first time.
I have several different versions, and they all generate the same issue. The tables I am creating are quite complex: multiple cells, colspans, images, nested tables, roll over colours, styles etc. At first, I believed it was an issue with creating images dynamically, however it now seems that is not the case.
I have also tried creating the table and tbody tags using the DOM and appending them to a div, but with no luck. I have also tried creating the tables using a hidden object and then copying the innerHTML / nodes across to the visible one. The various versions I have cover most bases:
* using innerHTML to add content to the cells * using the javascript DOM to create all elements and append them * using a mixture of the both
If anybody has any feedback or suggestions then it would be really appreciated, particularly related to the following:
* From your experience, is this realistically possible?
* Is the problem I'm experiencing related to the complexity or size of the table I am trying to generate? If the table is simple text only, with 2 or 3 columns and rows, then it does work.
* What is the best method to dynamically create tables and cell content across browsers, and in Mac IE?
* Is the problem image related? Does anyone have experience of creating images dynamically in tables in Mac IE? Do you use "new image()" or createElement()? (using the small table sample, this was possible using both methods, and also innerHTML on a cell).
I'm dynamically creating a table. I create the <tr>s with five <td>s. I then remove the third <td> and would like to add the cell variable where I removed the td. The creation of the table works, the removal of the td works, now how do I add the cell var where I removed the td? Example here: [URL]
Code JavaScript: function CreateTable() { var array = ["one", "two", "three", "four", "five", "six", "seven", "eight", "one", "one", "three", "seven"]; var listItems = ""; var tbody = $('.tbody'); var cell = $('<td>', { className: 'open', html: 'Open' }); $.each(array, function(index, val) { var row = jQuery('<tr></tr>') .append('<td>' + index + ' - ' + val + '</td><td> open </td><td> open </td><td> open </td><td> open </td>'); $('td:eq(2)', row).css('background-color', '#eee'); $('td:eq(2)', row).remove(); row = row.add(cell); row.appendTo(tbody); }); }
Environment is PHP - MYSQL When the user changes the value of a select drop-down, I want to use Ajax and query one table of my database, retrieve three pieces of data, and place the data in three separate text fields in my form. Is there a simple tutorial out there that explains this?
I get the general concept of the separate php file for the query, but I'm pretty much lost.
I have a form that has a pretty complicated combo box - a user starts typing text, it queries a database for matches, and displays the results to the user. The user can then select the match they desire and it has a value id, which I am currently sending to a hidden field in the form. So, for example: user starts typing in a movie name, Seven - it returns Seven and user selects it. The form submits the id of the movie seven (say 12) to a hidden field.
Where I am stumped: Once a user selects a movie title, I have another drop down select box that is to display the available formats of the movie by querying my database based on the product id (12) and returning the available formats in the list:
DVD BLUERAY VHS
I am pretty good at programming, but I cannot figure this out - how to make the select box fire and return results once the value for the textbox has been captured.
What I'm trying to do here is to create an editing form based upon the field descriptions extracted from a database, and use jQuery (e.g., datepicker) to handle the input. So, using the datepicker example, I create an input item, make it a 'text' type, give it a name and an id, and then use $('#'+textfld.id).datepicker({ ... }) to set it up. This is NOT done at $document.ready time, but while running the form's JavaScript, so I don't know if that's the problem or not; I can't see how to use $document.ready here due to the dynamic nature of each field.
AFAICT, what should happen here is that a jQuery datepicker should be created and associated with the text field - but nothing at all is happening.
I have a form with a number of <select> fields, some of which require additional fields to be displayed/enabled depending on which <option> is chosen. For example, in the following code, I'd like a <textarea> field to be displayed if users choose the 'Other' option:
<label for="venue_type"><p>What type of venue do you require?</p></label> <select name="venue_type" id="venue_type"> <option value="null">--Please choose--</option> <option value="Meeting/Training/Seminar room">Meeting / training / seminar room</option> <option value="Computer Suite">Computer Suite</option> <option value="Examination room">Examination room</option> <option value="Lecture theatre / auditorium">Lecture theatre / auditorium</option> <option value="Other">Other type of venue</option> </select>
I'm guessing that it's possible to do this using onchange, but am not too great with Javascript .
i have a search form, and the default value is "enter text here"when the user click the submit button, i would like to check if the value of my text input is "enter text here" and if it is, then don't submit the form (popup a warning or something)
Have the following code which (resides in a dialog box) and serves as an event listener for check boxes. Am able to populate / de-populate text field with values from check boxby checking or unchecking the individual check boxes:
// Event listener which picks individual contacts// and populates input field. $('#emailCheckListId_ul input:checkbox').change(function() { // Declare array var emails = [];
[Code].....
However, when I use try to use theJQuery Tagifyplug-in it only creates one "tagified dynamic label" inside the text field but doesn't create another label when I click on an additional check box. Also, when I uncheck the original checkbox, itdoesn't remove the original label.
Here's my code using the JQuery tagify plug-in (all I did was keep everything the same as above but called the tagify functionon the text field):
// Add / Remove array from text fieldtextField.value = emails; // Decorate with dynamic label $(textField).tagify(emails);
I get this JavaScript error in the browser:
jquery.tagify.js: 'options' is undefined, line 71
In the source code this line reads:
_setOption: function( key, value ) { options.key = value; },
Its stating that options.key is undefined...
To view the jquery.tagify.js complete source, clickhere.
Is there a way I can create an "else" for example:
// Iterate through each array and put email addresses into array$('#emailCheckListId_ul input:checkbox:checked').each(function(){ // do something });
