2014-02-09 Preface: After the first two days of work, mainly to adjust the working condition. The project is not very tight, taking advantage of the weekend to meet some of the year before some of JS and jquery some of the questions to sum up. This is mainly about the Extend method of JQuery and (function ($) {}) (jquery), as well as some related knowledge. 1. The difference between substring and substr in JS The substring method was used in the pro

Extend for objects is a common function. For example, javascript does not overload the function, and the parameter type of the function is not defined. Therefore, it is convenient to input an object as a parameter. The default value of the parameter object is usually provided in the function. In this case, the extend is used to overwrite the input parameter to the default parameter, for example: Code: The

How to Use extended method extend in Jquery: jqueryextend During Jquery development, extend is a common parameter processing function, especially for the use of default values. The Extension Method prototype of Jquery is: var v=$.extend(dest,src1,src2,[,src3...]); The function is to merge src1, src2, and src3 into the dest and return the merged dest. However, the

$. Extend: a small problem This article records a small problem that I encountered when using $. extend, as well as the cause analysis and solution. It is very practical. If you need it, you can refer to it. I have been working on mobile terminals recently. I am also familiar with jQuery. In addition, Zepto provides the same API as jQuery, so I chose Zepto as the development framework. Because it is mobile
