I am looking for a method to make a html element empty (no innerHTML). This would be pretty easy if it weren't for IE. IE has the bug that innerHTML is read-only for tables (and some other elements too). So my function
function clearElement(id){
document.getElementById(id).innerHTML = "";
}
doesn't work on tables (and I need it to work on tables). Would there be any other way for me to do this in a way as general as possible. I don't want to bother with 2 different functions for what is essentially the same task and I'm curious how this could be solved in a nice way.
What type of variable is an empty array element? I thought it was undefined, but i noticed that they have different behavior than undefined does:
var r=Array(1); var s=r.concat([0,"",null,undefined]); alert (s.toSource()) //==="[, 0, "", null, (void 0)]" typeof s[0] //==="undefined" typeof s[4] //==="undefined"
As you can see, 0 and 4 both === undefined. Yet, they don't have the same toSource()... Is this special type named anything specific? Or more importantly, can it be detected outside of an array as being distinct from undefined? I am thinking this would be the same type as ({}).nonProp ... I guess the question is actually, "can you tell the difference between uninitialized and undefined"?
I am not able to calculate the offsetwidth of the element which contains extra space in between the characters.for ex. if the element contains "A A" as a innerHTML value - if we calculate offsetwidth as 29 and also if the element contains "A A" value again I am getting the same offsetwidth as 29.While calculating the offsetwidth it is not calculating the empty space.May I know how to calculate the offsetwidth with the empty space because I need to insert the ellipsis (...) if it exceeds original width?
Code snipet function fitStringToWidth(title,width,className) { var span = document.createElement("span"); span.className="titleBar-Title-1";
I'm currently developing an online work brief, where the user has to enter details regarding the project into a form. I've come to a section in the form where the user has the option of selecting between two checkboxes and an input element. I have to ensure that at least one of the checkboxes have been checked or that the input element is not empty. I've come up with this function:
function validateMedia(){ var count = 0; if(document.workBrief.mediaOnline.checked){ count++; } if(document.workBrief.mediaPrint.checked){ count++; } if(document.workBrief.mediaOther.value != ""){ count++; } if(count 0){ return true; }else{ alert('Please choose at least one media option'); return false; }}
I'm sure there is a more effiecient way of writing this.
The situation is; I receive a response back from the server which i only a part of html code. e.g. a table like <table <tr><td>high</td></tr>........ </table>. In other words, I receive file as a response which has a part of html file.
My aim is to replace an existing document node with the new response.
If I run the following lines (JavaScript):
var parsedText = document.createTextNode(req.responseText); body.replaceChild(parsedText, toReplace)
It replaces the node 'toReplace' with html codes with the tags include which is not what I want. The html tags are not wanted but should display in correct format as specified by html (a tabular form if htm tag is <table>)
I got my code for adding my table ( HTML manipulation )But the problem is, that if u click an empty row, it need to change letter from S to Z ( and empty ( space ) So, i actually don't know how i can use those multiple's, so i started scripting from just an space to ... it didn't work.. but i was sure my script works, so i used it on other page .. and it worked ... here is my code
I`m trying to make selecting an select list option (as it become when we click on it)by clicking on a special pseudo element.I`m trying to do it in this way:
I'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.
.change() is only for form elements minus check boxes/radio buttons, etc.Are any of you aware of a script that does this already? Hopefully one that is easy to implement.I just want to monitor things like height, number of inner elements, or any change in the inner HTML.
I'm doing some work on a theme and I'm using horizontal accordion scrollers.
You can see on my practice page that the three main sections (on the right) are all different sizes. The rightmost section has a big block of text but it is all cut off after 600px (which is what I have it set as).
Since this will be for a blog there will be different sized pages with every click but I can't seem to find a way to have the elements default the height based on the amount of content.
The accordion script uses MooTools and you can see everything I've done on my development page.
Im trying to make the VALUE element within a form dynamic using JQuery and was wondering if the following is possible and if not what is the way to achive this?
I need to apply specific formatting to selected text via a button. for example, I select some text, click the 'bold' button which then replace the selected text with <b>selected text</b>
I want to make HTML appear as text to maybe write some snippets on a site. I know that there is a way to make < and > by using < and > but I would like something that were a bit easier to remember and quicker like maybe using jQuery to take the content from a snippet and turn it into regular text.

vBulletin uses a template system so I can't create a separate element for everything -- we have had several people ask for a "skip to the next post" feature and I'd like to implement that for them My first thought was to use anchor tags such as:
<a name="$post[postid]">
for each post and then to create a link for "Jump to Next Post" which would advance the user to the next instance of <a name="$post[postid]"> in which the postid obviously would've changed. With that I didn't know if there was a way that I could have javascript look for the next instance of this, or to pull the postid number and add 1 to it to find the next post on the page. I'm also not sure if it would need to be as complicated as reading where it was at and then adding one and directing person to that anchor point, which is why I thought maybe it could just look for the next instance of <a name="$post[postid]"> and refocus the screen on that.
It doesn't have to be an anchor, it can be a hidden input, whatever makes the JS be able to seek it as a point to move the page to. We do have some members that select a different number of posts per page than the default, so I'm guessing that the plus one might not be a great idea if they used a smaller number per page and then clicked the last one, whereas people with more per post wouldn't need to stop at the same point before it no longer let them. If there's a solution for that, that'd be great as well (such as once it hits the last element on the page, it no longer receives instruction, goes to the top of the page, or something).
We have a page that combines HTML with a Java applet. The applet has a big rectangle in the middle of the page. Above the applet we have some dropdown menus that are in HTML (and JavaScript and CSS). We would like to make it so the dropdowns can temporarily be visible on top of the applet, and it doesn't seem to work. The applet seems to completely own its rectangle, and nothing with CSS or Z ordering seems to work to draw temporarily on top of the applet.
Does anybody have ideas for how to do this? We tried one trick with an IFrame that seems to work in IE but not in Firefox or Safari.
At the moment, if I don't specifically click into the iFrame (it is in design mode) then when I paste the HTML it attaches itself to the main document rather than in the iframe 'body'.
My JS function at the moment is simply:
function doTable(tabledata) { if(tabledata != '') iHTMLeditor.document.selection.createRange().paste HTML(tabledata); }
but I think I need an extra line above the iHTMLEditor (my iframe's ID) bit to make sure it goes in there.
