How can I set the value of a textbox to the user entered value(it's a number).
<input type = "text" name = "somename" value = "">
User enters 3 in the textbox The code should transform to
<input type = "text" name = "somename" value = "3">
I have an ASP page that displays, along with other data, a list of items that refer to a specific element in a database. Instead of adding an Add button, I would like to display a text box below the last item in the list to have the user input any new data. Once they enter the data and hit Enter, the data they enter should then be added to the list and another text box added beneath this item (just as forms and tables in Access do). However, I'm not sure how to implement this functionality.
View 1 Replies View Relatedmy assignment is to create a script that will prompt users to enter a series of integers and display only the largest one. I'm having troubles figuring out how to set a var to the first item entered. I have set an array to load the #'s, and will use a for loop - does this sound right?
this is what i have so far:
Code:
var list = new Array [10];
var largest ;
function displayLargest() {
for (var i = 0; i < 10; i++);

Enter one value in textbox (number) , then click on button show on the screen number textbox that entered I did as follow:

function show() {
var x,i;
x = parseInt(f1.text1.value);
for (i=0 ; i<x ; i++) {
document.write("<input type='text'>");
document.write("<br>");
}
}
</script>
<body>
<form name="f1">
Please enter data <input type="text" name="text1">
<input type="button" value="submit" onClick="show();">
</form>
</body>
My program run exactly...but have a issue !
On screen display number textbox equals value that I entered, but content in <body> is cleared !
Show me the way to hold content in <body> and only display textboxs under them...?
Does anyone know of a place to get a code that looks at what is typed in a textbox and displays a green checkmark or a red x next to the textbox if the value entered is invalid. Eg. if no @ is entered in the email field, a red x would be shown next to the email field. Eg. if a zip code contains letters, a red x would be shown next to the zip code field. Eg. if the email field contains a @ and a period, a green check would be shown next to the email field. Etc. The green check or red x would have to be shown either as the user is typing or after they go to the next field (Blur).

I have a website where people can create posts similar to FB(I hate that example but it's widely known) -- how do I strip HTML tagging out of the post before I put it in my db?

I have a JavaScript application that needs to preserve double quote marks and apostrophes (" and ') that are entered into form fields by the user. The form data is passed through several screens using hidden fields.
Right now, apostrophes work because I have the input fields coded as value="". I have not found a way for JavaScript to retrieve the field's value if double quotes are entered by the user. If I change the parameter to value='' (single quotes) then the apostrophes probably won't work.
Is there a straightforward way for JavaScript to retrieve the field value containing quotes, so that I can manipulate it into a different string that can be easily passed between HTML pages?
In my asp page, I have a dropdown box and 2 textbox. The dropdown has "select" as the first value. If value is select in the dropdown, i want to make the textbox as readonly, else it can be used for inputting.
I tried this:
Code:
function OnChange(dropdown)
{
var myindex = dropdown.selectedIndex;
var SelValue = dropdown.options[myindex].value;
[Code].....
But, I am not able to set to readonly. How to make textbox readonly on the select change and body onload?
I'm setting up a fictitious shopping page which uses cookies to remember what a user has selected. The products are photographs that the user can select either framed or unframed versions and I'm trying to put a confirmation box if the user actually requests framed and unframed versions of the same photograph. The code I'm using actually worked before I tried to add this extra functionality but I can't work out how to test for this extra bit. Here's my code and it sets cookies with names as either lulworth01 for the unframed version or lulworth01f for the framed version. The bits that work are in black and my extra code for this test is in red.
function getCookie(name){
var index = cart.indexOf(name + "=");
if(index == -1)
return null;
index = cart.indexOf("=", index) +1;
var endstr = cart.indexOf(";",index);
if (endstr == -1) endstr = cart.length;
return unescape(cart.substring(index, endstr));
} function setCookie(name) {
if ((name.charAt(name.length-1)='f') && (getCookie(name.substring(0,10))!=null)) {
confirm("You seem to have placed orders for both a mounted and framed image of the same photograph.
Is that OK?");
} else {
alert("Thank you.
Your basket has been updated.");
x=parseInt(getCookie(name)) || 0;
y=x+1;
var today = new Date();
var expiry = new Date(today.getTime()+28*24*60*60*1000); // plus 28 days
document.cookie=name+"="+y+";expires="+expiry.toGMTString();
cart = document.cookie;
}}
I've got the following code snippet in a function to set a coockie based on whether or not the user selects a checkbox. Using an alert the cookie text looks fine but when I go to retrieve the values the only one it can find is the value for user. I've a few different things and none of them seem to work. I'm getting the same thing in both IE and Firefox. The only cookie listed is the 'user' with the proper expiration date. Code:

I'm trying to set a cookie when a user clicks a hyper link.
Do you think I should prevent the default behavior of pressing a link first, and then set the cookie?
Or could I just set the cookie on a hyper link click event, and hope the client sets the cookie, before they are directed to another page.
I've been reading about jquery and ajax and I'm not exactly 100% sure as to how to implement it. Essentially I have the following:
A textbox
A select box
Another select box
As the user fills data in the textbox and then clicks off I want the javascript to fire, submit the value in the textbox to a url (I can handle the backend side of it all fine) which will then send new data to the select boxes. Similarly for the second select box when a user clicks off (After selecting) I need the jquery to fire again. I've seen this code and think I get how to write it in, but I'm not sure how to do the (When user clicks off bit of it).
$.get('ajax/test.html', function(data) {
$('.result').html(data);
alert('Load was performed.');
});
On various video sites you can click cinema mode and the page goes dark, whilst you watch the video.
