I do undersand the basic notation of jQuery selectors, but I don't understand what the [0] means in the following code snipet:
$("body").append(
$([
overlay = $('<div id="lbOverlay" />')[0],
[code]....
While trying to get a selector to work with ids that include square brackets, I searched the forum and found that I needed to escape the brackets with '\'. However, while this works with my fiddle: can't get the exact same selector to work within my page in either FF or Safari. I've triple-checked the id and it is correct; I know that jQuery is working on the page because changing the selector to$('.nameinput') gives the expected results. can't change the id because I'm working within an existing application; I know I could add a class to the input and use that as the selector instead. I'd prefer not to and would just like to figure out why this isn't working.
View 1 Replies View Relatedhow do I get the post data from html in jQuery which contains square brackets?
[code]........
I'm hoping that someone can help me with a question I have about javascript syntax.
I got an html page that uploads an image and some text field to a database.
What I'd like to do is modify the content of one of the textfields prior to it being submitted to the database. Specifically, I need to append the contents of one of the fields to another.
The problem that I've encountered is that the textfield name contains square brackets , ‘extra_fields[Price]'
I've identified the square brackets as being the problem by changing the textfield's name to one that doesn't contain square brackets ,extra_fieldPrice for example and the script works fine.
Unfortunately, in the real world application of this page, I can't change the textfield name.
The specific part of the html page that's giving me problems is:
Can't figure out why the pattern will match a period but not a square bracket.For example, it will match "See Jack run." but not "See [Jack] run.". Just ignores the brackets.
Code:
var title = note_title.value;
// validate periods and brackets
[code]....
for the character classes [ ], if i want to match ,.[] i cannot put them into the square brackets so how to deal with that? what if the characters are . or ! or ." (<-- combined) it fails if the regexp is [.!(.")] which will treat ( as one of the element. also the book javascript: the definitive guide says that (?=p) requires that the following characters match the pattern p, but do not include those characters in the match. However, the browser failed to figure this out (IE8) i.e. "asd:ert".match(/(?=:)w/) returns null

Any suggestions on how the javascript below should be changed so it will work with checkboxes that have brackets in the name? (I'm using foreach in php, and can't seem to get the php to work/work correctly without using them.)

I know very little about javascript, but was wondering if something like this can be done?
Would it be possible (with mootools or jquery) to have homepage that will rotate its home page content forwards and backwards based on either triangle or square? ie, you can rotate through 3, 4, etch home pages?
Sort of like a slider, but it rotates off a center axis of the triangle or square?
I cannot manage to do a square root operation. I am using the coding:
var a = Math.sqrt(b);
getting an empty square character instead of a space.Looks ok printed by php.It seems to happen after I use rubout or delete and then type a space in my JS editor; when the edited text is displayed via ajax in a JS tooltip, I see an empty square.Hundreds of articles have this problem so I need a way to remove them. Iv'e tried various character replacements but can't seem to determine what the square character is (char code).

Basically what I need to do is take a number of elements, lets say 6 in this case, all of which are div's with an image child e.g.
<div class='triangle-element'>
<img src="../images/face.jpg" />
<div>
I have been looking for days for a way to do this but have made no progress.
The text looks fine in php but when displayed by javascript, some of the spaces are shown as an empty square symbol.
I have tried the following to change any unusual character to a space, but it doesn't help. code...
I believe that the character is created by a javascript-based editor when either the delete or backspace key is used to make an edit.
I have this strange symbol in many articles so I need a way to deal with this (the articles display fine when displayed by a php CMS).
I'm using javascript to show a preview of the article as a link tooltip.

is possible with JavaScript to drag and drop a .jpg from your desktop to a small square box on you website. On drop the picture has to upload the file and store it on the server.

View 3 Replies View Relatedmy javascript does not working after I retrieve a record that contains square symbol in the database. The square symbol should be a newline in a textarea. This is how the record "looks" in the table: [URL]
I am inserting the record using ASP and the value with square symbol is the value from a textarea with newline/enter. After that I retrieve the value using ASP and pass it to javascript and then the page is not working. If I retrieve other record which contain no square symbol then the script is working.
I'm trying to create a four-box form in which the user enters information into the first two boxes,and the program fills the second two boxes in.Basically,I need a form to calculate the square footage and cost of a vinyl banner.In the first text box the user would enter the banner's height.In the second box the user would enter the banner's width.
The third box would multiply the height by the width and display the total square footage of the banner.So far, I have this part down. The following is what I need help with: the fourth box.The fourth box needs to display the cost of the banner. I have a complicated pricing structure. For example:
If the total square feet for the banner is under 12 square feet, the cost is $60.00. If the square feet for the banner is between 13 and 25 square feet. The cost is $4.80/square foot and ect...I believe this would be done using some variation of an IF statement but I can't get it to work.Using this example, what would I add to the form to get this work? The following is the form I have so far which just consists of the calculation of the square feet which is all I've been able to get working.

I've been battling with this for a couple of hours now. I bet the answer is simple.
I want to take "text (just the text in here) more text" and end up with "just the text in here" No brackets
Basically I'm trying to strip a "url(address here)"
My regex literal so far is /[^(].*[^)]/g
This would work say for "(hello there)" -> "hello there", but fails for "text(hello there)text"
