I have been creating a little Javascript game. People buy items and then sell them for a profit. WHen someone buys something, it displays an image of the thing they just purchased (and have previously purchased). I want them to be able to "sell" the item by clicking on the picture. I have the money system set up, but I'm not sure about how to get rid of the picture when the user clicks on it. Is there anyway to get rid of a certain string (<img src="BLAH" class="BLAH">) when clicked on? I'm pretty sure you can use indexOf() somehow to do this, but I'm not exactly sure how
how can i use the .indexof function to check if there is a quote in the string. i can't seem to find the correct syntax for do this without an error occuring
my indexof() function is not being recognized when I enter an email address for an unsubscribe form I have on one of my pages. Additionally, the confirmation message is also not showing up when the email address IS valid. Here is my code that I am using on a PHP page:function Unsubscribe() {
var IsValid = document.getElementById("email").value; alert(IsValid.indexOf("@")); exit;
[code]....
to those PHP experts, I am aware of the RegEx function for validation, but I don't understand it, which is why I don't use it (in case anyone points that out).The other thing that is problematic is that the PHP code is automatically using HEADER() regardless of "email"'s value
I'm creating matrix of values like this:[code]Usually when i want to access position like Matriz[0][0] y retrived the value "", now for some reason when i debug appears "indexOf" at the beggining and when I access Matriz[0][0] I get "undefined".Someone knows why is happennig this, i'm using IE 6
jquery and a button delete, for remove rows of database.The problem is that I do not know how must input checkbox by clickable with click delete button sent to php code?my jquery code:
If you see my last post, it was a piece of this code that I was learning for/loops but now I have that all working(hence the new topic) and I'm having a problem with indexOf. Here's the whole script(its a fun little date picker)
function popSel(v){ var days; var x; if(v==01 || v==03 || v==05 || v==07 || v==08 || v==10 || v==12){ x = 31; }else if(v==04 || v==06 || v==09 || v==12){ x = 30; }else if(v==02){ /*var yr=document.getElementById("year").value / 4;*/ var yr = 2003 / 4; if(yr.indexOf(".") == -1){ /*If you divide a year by 4 and the value is a whole number, it's a leap year*/ x=28; }else{ x=29; }}for(i = 1; i <= x; i++){ days += "<option value=" + i + ">" + i + "</option>"; }document.getElementById("day").innerHTML=days; } The whole script works but feb doesn't change?
I'm trying to figure out how to make this code not be case sensitive when it comes to the "default.asp" line. The code below in the head of a XHTML template and adds the CSS info only on the homepage, which is domain.com or domain.com/default.asp. It works just fine, but when I visit [URL].. it doesn't work. How do I make it case insensitive?
(cant change typo in subject "my" "by") I have a script that deletes a model inside my client by a name however I only want it to delete once. here is my script:
Code: if (shape.name == itsdoof){ var shape_info = o3djs.picking.createShapeInfo(shape, sketchup [ii]);
the var shape_info = o3djs.pic..... bit is the script that deletes so ignore that however where it has if (shape.name == name) is there anyway to make it only pick up one shape.name and not all of them?
that's actually a "Delete" link , when I click it, there's a some sort of loading animation like stuff , similar to the thing that appears when one clicks the edit button of a thread here in this forum..then and it deletes the data and doesn't need to refresh the page, i guess it is ajax.....it's not my code.. now I was asked to alter it and use a pop up box to ask the clicker "Yes" or "No" before deleting the data , what or how to change that code snippet i pasted above
I need a simple, quick and efficient way to logically branch if I find a string is contained in another string in jquery Most other languages this can be resolved in one or two lines and it would be readable.
I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?
I have made a basic form, and I need to combine three values within my form, then create an md5 hash of this string.Then assign it to a hidden variable.My form is here...
Or I have created a pastebin of it here, for easy reading: http://pastie.org/1171757.So I need to be able to combine the three values into a string, create a md5 of the string, then call the value of the string into a hidden value all before posting the form.
I have a 4row x 1col table, I would like to drop all the content of row three. Since Mac IE5.2 does not suppport deleteRow method, I have also try to set the innerHTML='' but it does not work. How can I delete the node from DOM in other way?
When somebody logoff I clear few cookies that I set from my clents browser. I was wondering is there a way to write a javascript so that it also clear cooke set by someone else from the broswer.Suppose there is a cookie name LoginIBM can I clear that one too?
i created this little script that creates dynamically a row. my problem is that when i want to delete a row it always deletes the last one, they way i have it mind that it will only delete the selected row. Code:
if (confirm("Are you sure you want to delete '" + title + "'")) { window.location.href = 'http://www.example.com/delete.php?t=' + type + '&id=' + id; } else { return false; }}
i have a soccer-site, on which of course, can be kept track of played matches. Now the admin has to be able to set the number of goals, and then select who scored what goal.
I want a system where one can put a number in a textfield (NaN would return an error). Say the admin enters Ɖ'. Then three dropdown lists appear below that field, in them are the players. If he turns Ɖ' (goals) into ƈ', the lowest one has to be deleted, but the upper two have to stay, with an unchanged (already selected) value ...
Preferrably cross browser. I just can't seem to figure out, i've tried loads of innerHTML and document.write(), both didn't give me what i wanted (yet).
I have a list called drawPathList thats just a list of xy coordinates. I use this to construct a drawing on a map. However, people would like to be able to 'Undo' something that they have drawn, so I'd like to yank that last item in a given list.
drawPathList looks like this: 23,34||45,67||456,678||43,78
Can someone help me with a function to remove the last item in the list (regardless of length)?
