Can anyone tell me the best way to access a hidden object in a form? I could use a hard-coded index to the elements of the form, but it's too easy to add something before the hidden object and mess up the indexing. For example:
The form has a tagid of "myForm"
The hidden object has a tagId of "myHiddenObj"
I can get the form elements by using
var formElements = document.getElementById('myForm').elements
But there doesn't seem to be any way to do this:
document.getElementById('myHiddenObj')
Assuming I have the elements as obtained above, none of these have
worked for me either:
I have an object with a member function that changes something on the objects state. This works perfectly fine in the easy case. But when I use an $.ajax call within the function it doesn't work. Here is the example code and failing QUnit tests: [URL]
I am finding some unusual behavior with techniques I am using to show/hide/update data without having to refresh the page. I'm quite sure it's developer ignorance on my part and would be grateful for any suggestions.
My page has 10 tables with their visibility controlled by the user making a menu selection. For example, selecting menu_1 calls a function which displays table_1 by setting table_1's style display: block and hides tables 2-10 by setting their respective styles to display: none. Everything in this simple navigational approach works as expected.
I am also using the HTTPRequest object to update relevant objects on the page based on user input. The problem I am seeing is when the HTTPRequest object is used to update DOM objects contained within the "invisible" tables -- or more accurately within those tables having their style display:none. I have tried using both the HTTPRequest object's synchronous and asynchronous approach and am seeing the same results.
I've tested when all of the tables are "visible" by setting their style settings to display:block and HTTPRequest calls work as expected.
The other twist in my example is that these HTTPRequest calls are each making a SQL query and updating a chart object within the table, which may take about 500ms each to return. My initial impression is that it looks as if the page is being rendered too fast because any more than three charts on a page is when the charts start getting misplaced on the page. Again, everything works fine when all tables are visible.
Is this a known problem with HTTPRequest, or do I need to migrate my coding techniques to the 21th century?
I have a form. Upon submit, the data is sent to the server. Under certain conditions, the form is replaced via ajax with a set of radio buttons that offer the user a a choice.I need to access the radio buttons before I submit the form again.Normally I could just access the buttons with getelementbyid but it is not available, presumably because they were generated via ajax.I could submit the form just to access the radio buttons and then submit it again, but I'd like to avoid that.
Does "document.formName.elementName.disable" work on hidden form text elements? I have a form with some input fields that are associated with some hidden text fields and I would like to disable all of the categories inside the form when the page loads and only enable each category as it is needed. Code:
I want to get the code ( I cant write it Im still a newbie ) to check a form user/pass and trigger another hidden form.
Heres what going on:
Have created a form, Form 1 Login: it has a username and pass fields. It shares the page with a Members Login form.
I want javascript to check the user/pass on Form 1 Login against a user/pass I assign. I assume I can assign one in the Javascript code.
The script does not send the form to the server, it just checks to see that the user/pass agrees with what Ive assigned.
The script, if the user/pass is the same as I assigned, triggers a Registration form to pop up that Ive hidden with CSS left:-999em.
Now the script has fulfilled its function, its done. But heres what continues and Adobe BC does this part.
User fills out the pop up Registration form with any user/pass, their valid email and name.
Clicks Submit and the form sends the New user a new personal pass and new username via email.
User adds New user/pass to Members form and is allowed into the site.
This is a round about way but, I can not use php or server side in this process, BC does not allow server side only client side. So Im doing a work around. I know someone could find the Javascript even in a js folder. Tight security is not an issue. I researched this for weeks and BC tells me it will work with their system...I just dont know how to write it.
I'm creating a invoice application. In the JSP page user has an option to enter more than one location for each contract. I have created the JSP page. I face problem in calculating the total for the newlocation if user has added a new one. I'm posing my Invoice.jsp page below. Code:
I am undertaking an assignment where I have to create a webpage that reads values from a database, and generate the appropriate amount of sliders (scroll bars) according to the number of database entires. The webpage functions like this: On index.php load, it reads all the slider values from the database and automatically generates and sets each slider to that value On setting each individual slider to a new value by adjusting the slider, the code automatically updates the slider value in the database via AJAX.
So far I have gotten both functionalities to work successfully. There is just one problem with the 2nd functionality. I can only get one slider value to save to the database at a time. I know how to fix the problem, I just do not know to achieve it. I shall now illustrate via snippets of code:
I've been using some code to verify form data quite happily, but i've recently changed the way my form is structured, and I can't get it to work now.
Originally :
The form is called "form1", and I have selects called "PORTA", "PORTB" ... etc...
I then had javascript that accessed these selects as below, and it worked fine.
ind = document.form1.PORTD.selectedIndex; val = document.form1.PORTD.options[ind].value; dev = document.form1.PORTD.options[ind].text;
My form is now autogenerated, and form data is stored to file, so I now use an associative array for thte form elements (so that I can loop through them easily), The form elements names are now :
McuCfg[PORTA], McuCfg{PORTB} and so on
Now, I modified the javascript so that it now uses the McuCfg[] associative array :
ind = document.form1.McuCfg[PORTD].selectedIndex; val = document.form1.McuCfg[PORTD].options[ind].value; dev = document.form1.McuCfg[PORTD].options[ind].text;
When the script runs, I get the error
"document.form1.McuCfg.PORTD is null or not an object"
I have used the same notation that i know works for the "options" array although that's not an associative array.
I have 4 checkboxes in my form and wanna change the number (to be displayed) according to the selection made on the ListBox Menu
HTML PART of the code
<select name= "rights" onChange="chk_Count(this);"> <option value = 0 > Admin </option> <option value = 1> guest </option> </select>
<input type= "checkbox" name = "add" value = "on"> <input type= "checkbox" name = "edit" value = "on"> <input type= "checkbox" name = "delete" value = "on"> <input type= "checkbox" name = "view" value = "on">
I want that when I select Guest onle checkboxes for "ADD" n "VIEW" should be shown and when Admin is selected all four. but I am able to find out how to access those elements in the form and change their properties.
i am creating text box Elements using DOM if only user needs it by using Create Element
var element = document.createElement("input"); element.setAttribute("type", "Textbox"); element.setAttribute("name", "group[]"); newdiv.appendChild(element);
Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.
I have done this once before but it has been a while. How do I add a new form hidden field and value to an existing form and then submit the form within a function that can be run with an onclick event?
Assuming the name of my form was "form", I could access the value of the text fields by "window.document.form.FIELDNAME.value" and the select by "window.document.form.public.selectedIndex". But the page i'm working with has multiple products listed and so I've addopted a nming convention for the elements name's so that I could access it more efficiently in PHP. So for example, I'd have multiple products as such Code:
I have 1 form, and dozens of elements. In the select elements I use onchange="somefunc()". In this function I'd like to access and change the form element attributes (such as form.element.option[].value and form.element.option[].innerHTML).
Is there a way to access the element that has just changed (unsing onchange="somefunc()") by passing a "this.element" parameter to access the elements properties such as form.element.option[].value within the function?
