jquery easy ui datagrid 怎样设置宽度，让列永远百分之百填充

Posted 2023-04-03

fitColumns 参数设置为true可以达到你的要求,fit 参数可以让高度也自适应,这两个参数使用的前提是你放置grid的盒子有宽度和高度.

使用这个参数时也是要给columns设置width属性的,这时候的width相当于比例,如果width的值一样,则平均分配,如果有某一列width稍大,则该列在填充的时候也会稍微大一点。

PS:easyui的API是继承的,很多插件的属性都继承自父类,所以,如果你查看一个空间的api,但是没有找到合适的方法和属性,请查看它的父类的属性或方法。

jQuery是一个快速、简洁的javascript框架，是继Prototype之后又一个优秀的JavaScript代码库（或JavaScript框架）。jQuery设计的宗旨是“write Less，Do More”，即倡导写更少的代码，做更多的事情。它封装JavaScript常用的功能代码，提供一种简便的JavaScript设计模式，优化html文档操作、事件处理、动画设计和Ajax交互。

jQuery的核心特性可以总结为：具有独特的链式语法和短小清晰的多功能接口；具有高效灵活的css选择器，并且可对CSS选择器进行扩展；拥有便捷的插件扩展机制和丰富的插件。jQuery兼容各种主流浏览器，如IE 6.0+、FF 1.5+、Safari 2.0+、Opera 9.0+等。

参考技术A 我想正在用JQuery Easy UI的朋友一定很希望DataGrid能够自适应页面大小变化，目前我还没发现其自带此功能，因此简单写了一个实现方法，与网友们分享，也希望能够帮助有需要的朋友。

下面是我基于JQuery做的一个实现：
Js代码 收藏代码
/**
* JQuery扩展方法，用户对JQuery EasyUI的DataGrid控件进行操作。
*/
$.fn.extend(
/**
* 修改DataGrid对象的默认大小，以适应页面宽度。
*
* @param heightMargin
* 高度对页内边距的距离。
* @param widthMargin
* 宽度对页内边距的距离。
* @param minHeight
* 最小高度。
* @param minWidth
* 最小宽度。
*
*/
resizeDataGrid : function(heightMargin, widthMargin, minHeight, minWidth)
var height = $(document.body).height() - heightMargin;
var width = $(document.body).width() - widthMargin;

height = height < minHeight ? minHeight : height;
width = width < minWidth ? minWidth : width;

$(this).datagrid('resize',
height : height,
width : width
);

);

使用方法：
Js代码 收藏代码
$(function()
var datagridId = 'userDataGrid';

// 其他代码

// 第一次加载时自动变化大小
$('#' + datagridId).resizeDataGrid(20, 20, 300, 600);

// 当窗口大小发生变化时，调整DataGrid的大小
$(window).resize(function()
$('#' + datagridId).resizeDataGrid(20, 20, 300, 600);
);
);

在此补充一下，由于IE6下JS的执行效率很低，因此在让DataGrid自适应页面大小变化的时候，请将DataGrid的fitColumns属性设置为false，否则改变页面大小会导致IE出现一定时间的停顿。设置方法为：

$('#' + datagridId).datagrid(
title: '用户类型',
url: 'userType.json',
fitColumns: false,本回答被提问者和网友采纳 参考技术B 请参考API(http://www.jeasyui.net/plugins/183.html)
fitColumns 参数设置为true可以达到你的要求,
fit 参数可以让高度也自适应,
这两个参数使用的前提是你放置grid的盒子有宽度和高度

使用这个参数时也是要给columns设置width属性的,这时候的width相当于比例,如果width的值一样,则平均分配,如果有某一列width稍大,则该列在填充的时候也会稍微大一点
PS:easyui的API是继承的,很多插件的属性都继承自父类,所以,如果你查看一个空间的api,但是没有找到合适的方法和属性,请查看它的父类的属性或方法 参考技术C 不设置width属性，加上一个fixed设置为true.就可以自适应了。多看文档。 参考技术D 在外层套一个div作为容器，设置宽度100%

JQuery Easy Ui dataGrid 数据表格

Extend from $.fn.panel.defaults. Override defaults with $.fn.datagrid.defaults.

The datagrid displays data in a tabular format and offers rich support to select, sort, group and edit data. The datagrid has been designed to reduce development time and to require no specific knowledge from developers. It is both featherweight and feature-rich. Cell merging, multi-column headers, frozen columns and footers are just a few of its features.

依赖

• panel
• resizable
• linkbutton
• pagination

用法示例

Create datagrid from an existing table element, defining columns, rows, and data in html.

1. <table class="easyui-datagrid">
2. <thead>
3. <tr>
4. <th data-options="field:‘code‘">Code</th
5. <th data-options="field:‘name‘">Name</th
6. <th data-options="field:‘price‘">Price</th
7. </tr
8. </thead
9. <tbody>
10. <tr>
11. <td>001</td<td>name1</td<td>2323</td
12. </tr
13. <tr>
14. <td>002</td<td>name2</td<td>4612</td
15. </tr
16. </tbody
17. </table

Create datagrid via <table> markup. The nested <th> tags define the columns on the table.

1. <table class="easyui-datagrid" style="width:400px;height:250px"
2. data-options="url:‘datagrid_data.json‘,fitColumns:true,singleSelect:true">
3. <thead>
4. <tr>
5. <th data-options="field:‘code‘,width:100">Code</th
6. <th data-options="field:‘name‘,width:100">Name</th
7. <th data-options="field:‘price‘,width:100,align:‘right‘">Price</th
8. </tr
9. </thead
10. </table

Create datagrid using javascript is also allowed.

1. <table id="dg"></table

1. $(‘#dg‘).datagrid({
2. url:‘datagrid_data.json‘,
3. columns:[[
4. {field:‘code‘,title:‘Code‘,width:100},
5. {field:‘name‘,title:‘Name‘,width:100},
6. {field:‘price‘,title:‘Price‘,width:100,align:‘right‘}
7. ]]
8. });

Query data with some parameters.

1. $(‘#dg‘).datagrid(‘load‘, {
2. name: ‘easyui‘,
3. address: ‘ho‘
4. });

After changing data to server, refresh the front data.

1. $(‘#dg‘).datagrid(‘reload‘); // reload the current page data
