A. easyui datagrid 數據綁定 java

後台：

只需要將url綁定就好，他會自動獲得你的數據，進行顯示，希望能幫助到你

B. 菜鳥求教，java easyui 怎麼用DataGrid 的屬性queryParams給後台傳參數，DataGrid的代碼如下：

你上面的dataGrid應該只是個本地的例子吧，沒有和後台交互吧!因為我看你的url="mytable",感覺不像是action請求；因為你說的queryParams是需要發送遠程請求時，才起作用的；

這樣就會重新去發送新的url請求，初始化datagrid新的數據了；（我這樣的寫法是動態的設置請求參數，如果你想直接在datagird初始化中添加參數，你就直接在初始化datagird的時候添加屬性queryParams : {參數名:'參數值',}）

C. 如何用easyui+JAVA 實現動態拼湊datagrid表格

首先datagrid表格式智能顯示的只要你的json字元串符合特定格式就可以正確顯示。所以你需要做的就是在後台拼接好字元串發送到前台就行了，datagrid會自動顯示。
json字元格式：注意格式一定要正確。
{"total":28,"rows":[
{"proctid":"FI-SW-01","proctname":"Koi","unitcost":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},
{"proctid":"K9-DL-01","proctname":"Dalmation","unitcost":12.00,"status":"P","listprice":18.50,"attr1":"Spotted Alt Female","itemid":"EST-10"},
]}
上面是後台拼接好的字元串，可以使用fastjson-1.1.28.jar架包；架包只能將類或list或map轉為json字元串，而我們要的數據中多了兩個欄位：total和rows，所以還要建立一個封裝類。類中定義兩個變數：total和rows，rows是一個我們的數據集合，將這個類轉換成json字元串發送到前台就可以了。

如果前台要特定格式或樣式顯示可以使用datagrid的屬性來設置：
$('#dg').datagrid({
url:'datagrid_data.json',

columns:[[
{field:'code',title:'Code',width:100},
{field:'name',title:'Name',width:100},
{field:'price',title:'Price',width:100,
formatter: function(value,row,index){
if (row.user){
return row.user.name;
} else {
return value;
}
}

}
]]
});
這樣基本上就可以實現我們所需要的了。

D. Java項目用easyui做樹形列表後台代碼怎麼來准備數據啊不要概括型答案，要詳細過程的，謝謝！

教你怎麼解決,下次就知道了.

http://www.jeasyui.net/demo/581.html

訪問這個地址,是easyui的官網範例,可以看到範例的html裡面有這個配置treegrid_data3.json

所以官方的代碼用的是這個地址返回的json:http://www.jeasyui.net/demo/treegrid_data3.json.

訪問上面的地址,返回值就是你要的:

{"total":9,"rows":[
{"id":1,"region":"Wyoming"},
{"id":11,"region":"Albin","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},
{"id":12,"region":"Canon","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},
{"id":13,"region":"Egbert","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},
{"id":2,"region":"Washington"},
{"id":21,"region":"Bellingham","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":2},
