  • removeClass doesn't work on the second DIV tag

    - by kwokwai
    Hi all, I am learning JQuery and writing a simple data validation for the two fields in a HTML form: <FORM name="addpost" id="addpost" method="post" action="/add"> <TABLE BORDER=0 width="100%"> <TR> <TD>Topic</TD> <TD> <DIV ID="topic"> <INPUT type=text name="topic" id="topic" size="72" maxlength="108"/> </DIV> </TD> </TR> <TR> <TD>Comments</TD> <TD> <DIV ID="topiccontent"> <TEXTAREA rows="12" cols="48" name="content" ID="content"> </TEXTAREA> </DIV> </TD> </TR> <TR> <TD> <INPUT type="submit" value="Send"> </TD> </TR> </TABLE> </FORM> Here is the JQuery script for checking the data input from the form above: $('#addpost').submit(function(){ if($('#topic').val()==""){ $('#topic').addClass('hierror'); return false;} else{$('#topic').removeClass('hierror');} if($('#topiccontent').val()==""){ $('#topiccontent').addClass('hierror'); return false;} else{$('#topiccontent').removeClass('hierror');} }); Here is the CSS for the hierror class: .hierror{border-style:solid; border-width:12px; border-color:#FF0000;} ('#topic').removeClass('hierror') works but ('#topiccontent').removeClass('hierror') doesn't. Could you help me please?

  • Endless scroll paging in jquery Safari

    - by socheata
    I'm using : $(window).scroll(function () { if ($(window).scrollTop() + 10 >= ($(document).height() - $(window).height())) { loadContent(); } } It works fine with Chrome, IE, Firefox but except in Safari. In function loadContent, I used JSON to load data, as this tutorial. But while I test in Safari, It takes the content twice from JSON. If the other takes 9 items, then Safari takes 18 items. Does anyone know how to solve this problem? Thanks.

  • Dreaded iframe horizontal scroll bar can't be removed in IE?

    - by mrjrdnthms
    I have an iframe. The content is wider than the width I am setting so the iframe gets a horizontal scroll bar. I can't increase the width of the iframe so I want to just remove the scroll bar. I tried setting the scroll property to "no" but that kills both scroll bars and I want the vertical one. I tried setting overflow-x to "hidden" and that killed the horizontal scroll bar in ff but not in IE. sad for me.
