DWRUTIL

$("precloneNode1suf") 取得该对象;

DWRUtil.selectRange("selectRangeBasic", 5, 15) 选中selectRangeBasic文本框里面从第五个字符到第15个字符之间的字符.

DWRUtil._getSelection("selectRangeBasic") 得到selectRangeBasic文本框里选中的字符.

var arrayFive = [ 'One', 'Two', 'Three', 'Four', 'Five' ];
DWRUtil.addOptions('addOptionsBasic', arrayFive); 将数组添加到下拉菜单里面去;

DWRUtil.getValue('addOptionsBasic') 得到 addOptionsBasic 对象的值;
DWRUtil.getValue("precloneNode1Inner1suf", { textContent:true }); 后面加个参数,在 precloneNode1Inner1suf元素为"UL" 时,它返回了元素里面得值,也就是说去掉了HTML标签部分.

DWRUtil.getText('addOptionsBasic') 得到下拉框 addOptionsBasic 显示的文本;

var arrayObject = [
{ name:'One', value:'1' },
{ name:'Two', value:'2' },
{ name:'Three', value:'3' },
{ name:'Four', value:'4' },
{ name:'Five', value:'5' }
];
DWRUtil.addOptions('addOptionsObject1', arrayObject, "name"); 将数组添加到下拉菜单里面去;后面的参数是确定那个是给用户显示的文本,同时也是值;

DWRUtil.addOptions('addOptionsObject1', arrayObject, "name","value"); 同上,不过后面参数是: 3=文本;4=值;

var map = { one:1, two:2, three:3, four:4, five:5 };
DWRUtil.addOptions('addOptionsMap1', map); 同上, one 是值;1 是文本;
DWRUtil.addOptions('addOptionsMap1', map,true); 同上, 1 是值;one 是文本;

-------------------------------------------------------------------------------------
<ul id="removeItems">
<li>One</li><li>Two</li><li>Three</li><li>Four</li><li>Five</li>
</ul>

如果是列表显示,如上;则上面所有方法和select 下拉框使用一样;
-------------------------------------------------------------------------------------
DWRUtil.cloneNode('cloneNode1', { idPrefix:'pre', idSuffix:'suf' });克隆一个节点,参数一为要克隆的节点的id,第二个参数是在克隆的节点id前面加pre,后面加suf.(注意:如果该节点有子节点的话,子节点的名字也一样加)

DWRUtil.addRows(id, array, cellfuncs, [options]);
原理:

for each member in array
for each function in cellfuncs
create cell from cellfunc(array[i])
循环数组,循环函数,建立单元调用函数;(顺序决定)

例如:
DWRUtil.addRows('addRowsBasic', arrayFive, [
function(data) { return data; },
function(data) { return data.toUpperCase(); },
function(data) {
var input = document.createElement("input");
input.setAttribute("type", "button");
input.setAttribute("value", "DOM Test");
input.setAttribute("onclick", "alert('" + data + "');");
return input;
},
function(data) { return "<input type='button' value='innerHTML Test' onclick='alert(/"" + data + "/");'>"; }
]);

高级部分:
第四个参数为对单元的高级操作,主要下面的两个方法;
function defaultRowCreator(options) {
return document.createElement("tr");
};

function defaultCellCreator(options) {
return document.createElement("td");
};

例子:
DWRUtil.addRows( "demo2",[ 'Africa', 'America', 'Asia', 'Australasia', 'Europe' ] , cellFuncs, {
rowCreator:function(options) {
var row = document.createElement("tr");
var index = options.rowIndex * 50;
row.style.color = "rgb(" + index + ",0,0)";
return row;
},
cellCreator:function(options) {
var td = document.createElement("td");
var index = 255 - (options.rowIndex * 50);
td.style.backgroundColor = "rgb(" + index + ",255,255)";
td.style.fontWeight = "bold";
return td;
}
});

其中 options 参数的属性可用的为:(没试过,自己试试吧)

rowData: the element value from the array (the same for all cells in a row)
rowIndex: the key (if map) or index (if array) from the collection
rowNum: The row number counting from 0 in this section (so if you are using tbody, it counts rows in the tbody and not the whole table)
data: The 'computed' data value for the cell (cellCreators only)
cellNum: The cell number that we are altering counting from 0 (cellCreators only)


DWRUtil.setValues(); 批量设置值;
var settings = {
setValuesDiv:"setValuesDiv",
setValuesSpan:"setValuesSpan",
setValuesSelect:"two",
setValuesText:"setValuesText",
setValuesPassword:"AB",
setValuesTextarea:"setValuesTextarea",
setValuesButton1:"B1-Two",
setValuesButton2:"B2-Two",
setValuesRadio1:true,
setValuesRadio2:false,
setValuesRadio3:"one",
setValuesRadio4:"two",
setValuesCheckbox1:true,
setValuesCheckbox2:false
};
DWRUtil.setValues(settings);

DWRUtil.getValues(empty);批量获取值;
var empty = {
setValuesDiv:null,
setValuesSpan:null,
setValuesSelect:null,
setValuesText:null,
setValuesPassword:null,
setValuesTextarea:null,
setValuesButton1:null,
setValuesButton2:null,
setValuesRadio1:null,
setValuesRadio2:null,
setValuesRadio3:null,
setValuesRadio4:null,
setValuesCheckbox1:null,
setValuesCheckbox2:null
};
DWRUtil.getValues(empty);

DWRUtil.useLoadingMessage("Ping");//类似gmail那个样子,在右上角显示加载"ping";可用自定样式,具体查询;http://getahead.ltd.uk/dwr/browser/util/useloadingmessage

DWRUtil.toDescriptiveString("id",数字);弹出调试信息,数字为0,1,2.一级比一级高.

DWRUtil.onReturn(event, submitFunction);一般在form表单里面,防止在文本框上按回车就提交表单.
例如:
<input type="text"
onkeypress="DWRUtil.onReturn(event, submitFunction)"/>
<input type="button" onclick="submitFunction()"/>
