$(
"
precloneNode1suf
"
) 取得该对象,和document.getElementById(
"
"
)一样;
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.

[
'

,
'
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
=

'
},

}
];
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;

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)。比如:DWRUtil.cloneNode(
'
Node
'
, { idPrefix:
"
a
"
, idSuffix:
"
b
"'
}); 得到的节点的ID为aNodeb;
DWRUtil.addRows(id, array, cellfuncs, [options]);
原理:
for each member in array
for each function in cellfuncs
create cell from cellfunc(array)
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
'
>"; }
]);
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()"/>
