Table header is not fixed with Jquery fixheadertable plugin

If you load the table result into a div like the following, where you try to fix the height with css with overflow, the header will not be fixed after scrolling

     <div id="divA21InvResult" style="height:300px;overflow:auto"></div>  

Instead you should add the option "height" when you call the fixheadertable function and pair with a simple div without any height declaration in css

       <div id="divA21InvResult"></div>  

        $('#tblA21InvPrint').fixheadertable({
                    caption     : '',
                    height      : '300',                   
                    colratio    : [30, 50, 100, 100, 50, 515, 80, 400, 400],                  
                    sortable    : true,
                    sortedColId : 1,
                    dateFormat  : 'd-M-Y',
                    resizeCol   : true, 
                    sortType    : ['string1','integer', 'date', 'string', 'string', 'string', 'float', 'string', 'string'],
                    textAlign   : ['center','right','center','center','center','left','right','left','left']
                });

Error Placement Issue with Jquery Validation Plugin

I encountered the above problem with jquery validation plugin where the error message spans into multiple lines, eventhough there is more than enough span after the input element.

To solve this problem, you may add in the following css

label.error{
    color:red;   
    width:auto; /*Add this line*/
}

给宠物狗的鞋子 ： 一双/两双？

周五，吃了晚饭和同事到新开的宠物店闲逛。一边赞叹琳琅满目的宠物食/用品，同事指了指包装精美的四只宠物狗鞋子。

下意识的，我回应说“不错哦，有两双可以替换”。。。。

“两双？”，同事楞了楞说道。

我说“对啊，四只不就两双吗？”。。。。

“狗有四只脚。。。。”

哈哈，惯性思维。总想着人就一双两只鞋呗，所以见到四只鞋子就理所当然的以为是两双，还“替换”呢！

其实日常工作中，常有因为惯性思维而闹笑话的事，很多时候当事人并不知晓犯了什么错误，就像我一样，愣是得意着。

注：请不要咬文嚼字计较四只，该说是一套/一双/两双？重点在于“替换” 与 “惯性思维”
