基于jQuery排序及應(yīng)用實(shí)現(xiàn)Tab欄特效
更新時(shí)間：2022年03月20日 09:35:38 作者：小白可別不舉鐵
這篇文章主要介紹了基于jQuery排序及應(yīng)用實(shí)現(xiàn)Tab欄特效，jquery是基于JavaScript語(yǔ)言寫出來(lái)的一個(gè)框架，它封裝JavaScript常用的功能代碼，提供一種簡(jiǎn)便的JavaScript設(shè)計(jì)模式，但實(shí)質(zhì)上還是js，所以JQuery也屬于網(wǎng)頁(yè)編程語(yǔ)言。下面更多內(nèi)容需要的小伙伴可以參考一下
一、jQuery排序
eq（）排序，可以看作是一個(gè)篩選方法
- jQuery 中獲得的對(duì)象，內(nèi)部包含選擇的一組原生 js 對(duì)象，在 jQuery 對(duì)象中會(huì)進(jìn)行一個(gè)新的大的排序，這個(gè)排序與原來(lái)的 HTML 結(jié)構(gòu)沒(méi)有關(guān)系。
所以eq() 方法在 jQuery 對(duì)象中通過(guò)下標(biāo)獲取某個(gè)對(duì)象，下標(biāo)是 jQuery 對(duì)象中的大的排序的下標(biāo)。
//選中所有p標(biāo)簽
var $ps = $("p");
//生成了一個(gè)jquery對(duì)象，內(nèi)部包含了所有的元素js對(duì)象
// 是一個(gè)類數(shù)組對(duì)象，內(nèi)部會(huì)按照獲取順序進(jìn)行一個(gè)大排序
// 排序與自己原來(lái)的父級(jí)沒(méi)有關(guān)系，只與在jQuery對(duì)象中的新的位置有關(guān)
// 給指定位置對(duì)象添加顏色
$ps.eq(1).css("background-color","pink")
$ps.eq(4).css("background-color","skyblue")
$ps.eq(8).css("background-color","purple")
$ps.eq(7).css("background-color","lightgreen")
$ps.eq(10).css("background-color","orange")
//對(duì)所有獲取的元素進(jìn)行了排序，跟原來(lái)的結(jié)構(gòu)沒(méi)有關(guān)系
第三組div里p標(biāo)簽
<div class="b3">
? ? ?<p></p>
? ? ?<p class="b2p"></p>
? ? ?<p></p>
? ? ?<p></p>
? ? ?<p></p>
</div>
----------
<script>
? // 通過(guò)類名選中標(biāo)簽
? $(".b2p").eq(2).css("background-color","red")
? //得到第3組類名為b2p的 p 標(biāo)簽，讓它變成紅色
</script>
二、index（）方法
- jQuery 對(duì)象調(diào)用
index()方法時(shí)，得到的是它自己在 HTML 結(jié)構(gòu)中的兄弟中的下標(biāo)位置。與新生成的jQuery 對(duì)象內(nèi)部的大排序沒(méi)有關(guān)系。 - 它依賴于自身元素在父級(jí)中同級(jí)元素之間的位置
//index（） 兄弟中的排序
$ps.click(function(){
? //點(diǎn)擊輸出自己的index值
? console.log($(this).index());
})
上圖為依次點(diǎn)擊圖中p標(biāo)簽后，所顯示結(jié)果
jQuery中設(shè)置排他方法，在jQuery中可以通過(guò)this特殊設(shè)置進(jìn)行鏈?zhǔn)秸{(diào)用，讓兄弟通過(guò)siblings方法，批量設(shè)置成默認(rèn)效果。
三、應(yīng)用：Tab欄特效中的排他
- 自己的級(jí)別的排他：給自己this添加（要添加的屬性）類名，讓其他的兄弟刪除該類名。
- 對(duì)應(yīng)的部分的排他：給對(duì)應(yīng)位置的元素添加 （要添加的屬性）類名，其他兄弟刪除該類名。
- 找對(duì)應(yīng)關(guān)系，使用的是自己的index（）下標(biāo)，讓另一組中下標(biāo)相同的項(xiàng)作為對(duì)應(yīng)項(xiàng)。
- 通過(guò)選中另一組的對(duì)應(yīng)項(xiàng)利用eq（）方法選擇下標(biāo)項(xiàng)。

出現(xiàn)問(wèn)題
解決方法：span和ul的查找全部使用鏈?zhǔn)秸{(diào)用，通過(guò)節(jié)點(diǎn)關(guān)系查找
<script src="../jq/jquery-1.12.4.min.js"></script>

jQuery 對(duì)象進(jìn)行的操作都是批量操作，批量操作只能執(zhí)行一些簡(jiǎn)單的效果，如果想對(duì) JQ 對(duì)象中的每一個(gè)元素以及內(nèi)部的后
代元素進(jìn)行一些復(fù)雜操作，程序很難執(zhí)行
each（）遍歷
each（）的參數(shù)是一個(gè)函數(shù)
作用：對(duì)jQuery對(duì)象中的元素每一個(gè)都執(zhí)行函數(shù)內(nèi)部的操作
each方法基本原理就是for循環(huán)，從對(duì)象的下標(biāo)為0的項(xiàng)一直遍歷到最后一項(xiàng)，然后對(duì)每一項(xiàng)進(jìn)行操作
優(yōu)點(diǎn)：
each的函數(shù)內(nèi)部也有一個(gè)this，指向的是進(jìn)來(lái)遍歷的每一次的元素。
<body>
?<div class="box">
? ? <p></p>
? ? <p></p>
? ? <p></p>
? ? <p></p>
? ? <h2>h2</h2>
?</div>
?<div class="box">
? ? ? <p></p>
? ? ? ?<p></p>
? ? ? ?<p></p>
? ? ? ? <p></p>
? ? ? ? <h2>h2</h2>
? </div>
? ?
</body>
? ?
<script src="../jq/jquery-1.12.4.min.js"></script>
<script>
var $box = $(".box");
//每個(gè)div內(nèi)的第二個(gè)p添加紅色
$box.each(function(){ ?
? ?$(this).children().eq(1).css("background-color","pink");
})
</script>each的函數(shù)可以傳一個(gè)參數(shù)i，i表示的是這一次的遍歷對(duì)象在整體的jQuery對(duì)象大排序中的下標(biāo)位置
? //通過(guò)each()操作
$ps.each(function(i){
?// i 記錄的是這一次遍歷時(shí)，當(dāng)前元素在jQuery對(duì)象大排序中的位置
? ? ?$(this).click(function(){
? ? ?console.log($(this).index())
? ? ?//這個(gè)內(nèi)部的this是事件源
? ? console.log(i);
? ? ?})
?})
同理，如果想實(shí)現(xiàn)表格隔列變色的話，依靠jQuery大排列順序來(lái)實(shí)現(xiàn)奇偶不同變色的話，后期若給表格再添加列，都會(huì)出現(xiàn)問(wèn)題，無(wú)法對(duì)應(yīng)。所以使用each（）方法，將每一行作為一個(gè)操作單元，讓每一行中的列進(jìn)行隔列變色
var $trs = $("tr");
$trs.each(function(){
? ? $(this).children(":odd").css("background-color","skyblue");
})另一種方法就是使用td判斷，只要不使用jQuery的大排序，就不會(huì)影響后期插入列
$("td").each(function(){
? ? //判斷當(dāng)前td在父級(jí)中所處的位置
? ? if($(this).index() % 2 == 0){
? ? ? ?$(this).css("background-color","skyblue");
? ? }
