作為web前端初學者，今天要記錄的是三個控件的使用心得，分別是表格控件jqgrid，樹形控件ztree，圖表控件echarts。下邊分別進行描述。
1.jqgrid
先放官方demo網站上來，http://blog.mn886.net/jqGrid/，上面的描述還蠻有幫助的。
jqgrid的新增是比較簡單的，就是下載好之後將js檔案和css檔案分別放在對應的目錄下，使用時依照
<link rel="stylesheet" type="text/css" media="screen" style="color: #000000">
href="style/ui.gqgrid-bootstrap.css"/>
<script src="js%5Cgrid.locale-en.js" type="text/javascript"></script><br><span style="font-size: 14px">分别从相关目录下引用就可以了。<br>下边介绍一个简单的实例并且说下其中参数的设置<br></span>
<script type="text/javascript"><span style="color: #000000">
$(document).ready(<span style="color: #0000ff">function<span style="color: #000000">(){
$("#list4"<span style="color: #000000">).jqGrid({
url:"data.json"<span style="color: #000000">,

width:1000<span style="color: #000000">,
height:700,<span style="color: #008000">//<span style="color: #008000">高度，表格高度。可为数值、百分比或'auto'
colNames:['Customer ID', 'Company Name', 'Phone','City'<span style="color: #000000">],
colModel:[
{name:'CustomerID', width:'20%',align:'center'<span style="color: #000000"> },
{name:'CompanyName', width:'15%',align:'center'<span style="color: #000000">},
{name:'Phone', width:'20%', align:"center"<span style="color: #000000">},

],
rownumbers:<span style="color: #0000ff">true,<span style="color: #008000">//<span style="color: #008000">添加左侧行号<span style="color: #008000">
//<span style="color: #008000">altRows:true,//设置为交替行表格,默认为false
sortname:'CustomerID'<span style="color: #000000">,
sortorder:'asc'<span style="color: #000000">,
viewrecords: <span style="color: #0000ff">true,<span style="color: #008000">//<span style="color: #008000">是否在浏览导航栏显示记录总数
rowNum:15,<span style="color: #008000">//<span style="color: #008000">每页显示记录数
rowList:[1,2,3,4,5,6,7,8,9,10,10],<span style="color: #008000">//<span style="color: #008000">用于改变显示行数的下拉列表框的元素数组。
<span style="color: #000000">jsonReader:{
id: "blackId",<span style="color: #008000">//<span style="color: #008000">设置返回参数中，表格ID的名字为blackId
repeatitems : <span style="color: #0000ff">false<span style="color: #000000">
},
autoScroll:"false"<span style="color: #000000">,
emptyrecords: "Nothing to display",<span style="color: #008000">//<span style="color: #008000">单元格为空时的提示
celledit:"true",<span style="color: #008000">//<span style="color: #008000">启动单元格编辑功能
pager:$('#gridPager'<span style="color: #000000">)
});
<span style="color: #008000">//<span style="color: #008000">navgrid用于设置toolbar
$("#list4").navGrid('#gridPager'<span style="color: #000000">,
{
edit:<span style="color: #0000ff">true,add:<span style="color: #0000ff">true,del:<span style="color: #0000ff">true,search:<span style="color: #0000ff">true,refresh:<span style="color: #0000ff">true<span style="color: #000000">,
view:<span style="color: #0000ff">true,poition:"left",cloneToTop:<span style="color: #0000ff">false<span style="color: #000000">
}
);
});
</script>現在存在的問題主要是兩個，一個是關於頁面佈局的問題，就是weight和height經常無法約束這個表格，還有不明所以的線出現，同時滾動條的使用也比較奇怪，第二個就是瀏覽導覽列的問題，無法和表格的佈局調整在一起，經常出現亂跑和只顯示局部的問題。
解決了一個顯示兩個橫向捲軸的問題
<!--此行代码用来解决有两个横向滚动条的问题 -->
$("#jqGrid").closest(".ui-jqgrid-bdiv").css({ "overflow-x" : "hidden" });
理想狀態下我想達到的效果就是這樣有表格和下邊的導航條

還有的就是用的資料格式json，控制時用和json中同名的的id控制。
jqgrid先說到這裡吧，有了新的理解再說。
2、ztree
還是先附上官方網址：http://www.treejs.cn/v3/demo.php#_102。
引用方式還是這樣
<span style="color: #008080">1</span> <link rel="stylesheet" href="styles/demo.css" type="text/css"> <span style="color: #008080">2</span> <link rel="stylesheet" href="styles/zTreeStyle.css" type="text/css"> <span style="color: #008080">3</span> <script type="text/javascript" src="js/jquery-1.4.4.min.js"></script> <span style="color: #008080">4</span> <script type="text/javascript" src="js/jquery.ztree.core.js"></script>
先附上一個最簡單的樹來舉個栗子

現在需要解決的問題主要有兩個，一是樹形結構沒了，所有的文字出現在了同一列，沒有了縮排。二是如何引用json資料來控製而不是直接輸入。解決了再po上來。
再說兩個其他的，一是樹的樣式調整的位置是在demo.css檔案裡，裡邊有一項ztreedemo的選項，將他改為自己要用的名字，同時在
第二個是整個樹的樣式，就是修改ademo中的a標籤就可以了。
第三個是echarts，坦白講這個插件是這三個中使用最爽的了。
先附上官網網址：http://echarts.baidu.com/。
引用這個外掛只需要
就可以了。
先附上最簡單的實作。
