给多选列表添加可输入的功能

泄露秘密 提交于 2020-04-08 08:12:08
我们在做类似于管理系统这样的项目的时候,常常会碰见这样一个难题,如何给之前已经写好的select多选框添加输入功能,当然方法是有很多种,我这里给大家推荐一个最简单,效率最高,当然样式也是最优雅的一种方法,就是利用插件chosen.jquery.js。下面说一下它的用法: 1.在页面中引入css和js文件 <link href="../css osen.css" rel="stylesheet" type="text/css"> <script src="../js b osen.jquery.js"></script> 2.选择你想要添加输入功能的多选框,给这个多选框添加一个类名chzn-select <select class="chzn-select"> <option value="0" selected="true">请选择</option> <se lect> 3.在页面的js代码中书写这样一段话: $(".chzn-select").chosen({ search_contains: true }); 以上就是chosen.jquery.js最基本的用法,如果想使用更多请参考官方文档。 来源: https://www.cnblogs.com/nununu/p/7675784.html

Python-numpy.where() 用法

谁都会走 提交于 2020-03-20 13:20:49
numpy.where ( condition [, x , y ]) numpy.where() 有两种用法: 1. np.where(condition, x, y) 满足条件(condition),输出x,不满足输出y。 如果是一维数组,相当于 [xv if c else yv for (c,xv,yv) in zip(condition,x,y)] >>> aa = np.arange(10) >>> np.where(aa,1,-1) array([-1, 1, 1, 1, 1, 1, 1, 1, 1, 1]) # 0为False,所以第一个输出-1 >>> np.where(aa > 5,1,-1) array([-1, -1, -1, -1, -1, -1, 1, 1, 1, 1]) >>> np.where([[True,False], [True,True]], # 官网上的例子 [[1,2], [3,4]], [[9,8], [7,6]]) array([[1, 8], [3, 4]]) 上面这个例子的条件为 [[True,False], [True,False]] ,分别对应最后输出结果的四个值。第一个值从 [1,9] 中选,因为条件为True,所以是选1。第二个值从 [2,8] 中选,因为条件为False,所以选8,后面以此类推。类似的问题可以再看个例子:
