Show and hide tabs

问题 I'm trying to get a basic jQuery tabs solution working. I would like the tabs to render only when a link is clicked. Following the jQuery example here I can get the tabs showing no problem on my localhost, but as soon as I introduce a link to the page the tabs no longer render and instead the underlying tab content is displayed. Looking through Stackoverflow I see answers suggesting the use of the hide() method but I don't know: if this is the way to do it - i.e. create the tabs on page load

How do I return the response from an asynchronous call?

阅读更多关于 How do I return the response from an asynchronous call?

问题 I have a function foo which makes an asynchronous request. How can I return the response/result from foo ? I tried returning the value from the callback, as well as assigning the result to a local variable inside the function and returning that one, but none of those ways actually return the response (they all return undefined or whatever the initial value of the variable result is). Example using jQuery's ajax function: function foo() { var result; $.ajax({ url: '...', success: function

Table表头与数据列对齐问题解决方案

阅读更多关于 Table表头与数据列对齐问题解决方案

　　产品要求是一个页面要显示几千条数据，表格的表头固定，而内容在超出table的高度后，还能自由滚动。　　公司前端框架采用easyui，而用easyui展示几千条数据的话，耗时需要在几秒钟，所以我就自己写了一个table，展示如下。大部分朋友如果遇到这种情况的话，那么首先会想到做两个table，表头一个，数据体一个。我的写法是只有一个table。（需要注意的是最后一列一定不要设置宽度，如果设置的话整体会往右移动，会导致表头与数据对不齐的情况）。如下代码是我写的一个demo，动态绑定数据。代码如下: < html > < head > < meta http-equiv ="Content-Type" content ="text/html; charset=utf-8" > < style > table tbody { display : block ; height : 500px ; overflow-y : scroll ; } table thead, tbody tr { display : table ; width : 100% ; table-layout : fixed ; } table thead { width : calc( 100% - 1em ) ; background : #e9f5f7 ; } table { border-width
