数据与视图 如何根据数据渲染视图思路? 1:了解已知的数据接结构 2: 知到你要的数据是什么 3: 知道你的页面结构是什么？ 4: 想办法拿到你想要的数据；方式有：数组对象的遍历；数组内置API 字符拼API 字符串变数组；数组变字符串，等基本操作。 5：看数据获取到的数据与你搭建的页面结构是否符合？ 6：让你获取的数据与你搭建的页面结构相吻合。想办法：处理数据或者调整html结构 实现样式 7：将数据渲染到页面中 常见数据处理 1: 数组 对象遍历 增 删 改 2: 利用数组内置API 3: 字符串变数组；目的为了更好处理数据 4：数组变字符串。 5：字符串内置API 数据结构不符合时候,如何对数据进行重构? 1: 相同荣类型的数据用放在数组中； 2：有区别的数据放在对象中。区别为属性； 3：数据结构要符合页面htMl 结构 二级联动 1: 遍历1一级的内容 1.5 二级内容初始化。根据一级初始化数据 遍历二级内容 所有初始化只执行一次 2：根据用户选择的内容获取二级的数据 select.value 方式二 select.options[select.options.selectedIndex]; 给一级select 绑定onchange 事件；每次内容改变时候；都获取用户选择内容 3: 根据获取二级数据 二级内容； 如何获取用户选择的一级内容 三级联动 0： 一级 二级

问题 Consider a markup such as <select id="blah"> <option value="3">Some text</option> <option value="4">Some text</option> <option value="8">Some text</option> // <---- target this tag based on value 7 <option value="19">Some text</option> </select> Suppose I have a value with me, say 7. Is it possible to target the option tag whose value attribute is closest to 7 which, in this case, would be <option value="8"> ? I'm aware of ^ which means starting with and $ which means ending with and was

To understand the practical use of Grep's option -H in different situations

由 可紊 提交于 2019-12-21 05:08:07
问题 This question is based on this answer. Why do you get the same output from the both commands? Command A $sudo grep muel * /tmp masi:muel Command B $sudo grep -H muel * /tmp masi:muel Rob's comment suggests me that Command A should not give me masi: , but only muel . In short, what is the practical purpose of -H ? 回答1: Grep will list the filenames by default if more than one filename is given. The -H option makes it do that even if only one filename is given. In both your examples, more than

How to find select option position?

由 家住魔仙堡 提交于 2019-12-21 04:23:07
问题 I'm trying to find an option's index. For example, I would like to get 1 when I run the following fake code JS: $("#test[value='USD']").index() ? HTML: <select id='test'> <option value='CNY'>CNY</option> <option value='USD'>USD</option> </select> is this possible? 回答1: You were very close, you want to use index on the option element, not the select : var i = $("#test option[value='USD']").index(); Gratuitous live example Note that this will break if your select contains optgroup elements.

Magento - configurable product option images

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-21 02:46:34
问题 I'm currently working on getting images for product options showing up on my first magento build. I have THIS figured out for bundled product, like so: I'm obtaining urls of related images (swatches, for example) when the options for the select gets built. Now I'm trying to do the same with configurable products, but it does not seem to be as straightforward. Configurable products are built from simple products which represent each iteration of available options. Great. I can obviously upload
