我已经设法从PHP文件中的数据库中获取数据.从那里(data.php),
$output = json_encode($result);
结果就是这样,
$output=[{"kitty":"Whitely"},{"kitty":"Tabby"},{"kitty":"Ruby"},{"kitty":"Silver"}]
那么如何以php格式给出一个名为"kitten"的kitty对象？
例如喜欢
"kitten":[{"kitty":"Whitely"},{"kitty":"Tabby"},{"kitty":"Ruby"},{"kitty":"Silver"}]
嗨,我将新按钮设置为禁用.我正在使用Dojo 1.8
请参阅下面的代码: -
require(["dojo/parser", "dijit/layout/BorderContainer",
"dijit/form/Button","dojo/on","dijit/form/Select",
"dojo/store/Memory", "dojo/request","dojo/domReady!"
],
function(parser, BorderContainer, Button, on, Select, Memory, request)
{
var btn4 = new Button // Button, not button
({
label: "Number of cards",
this.set("disabled", false) // This code that disables the button
},"btn4");
btn4.startup();
})
我无法在Dojo或google中找到帮助.
嗨如何在dijit/form/select中以编程方式为每个选项添加粗体和字体大小等样式？
ready(function()//This function won't run until the DOM has loaded and other modules that register have run
{
parser.parse();
var select_Card = new Select
({options:
[
{label:"Select Card", value:"", selected:true},
{label:"Mk7ABC Card", value:"testdata1970_05", selected:false},
{label:"Mk7CBC Card", value:"testdata1970_10", selected:true},
{label:"Mk10DC Card", value:"testdata2060_03", selected:false},
{label:"Mk6BC Card", value:"dbProdigy", selected:false},
{label:"Mk6NBC Card", value:"dbProdigy_MK6N", selected:false},
], style:{width:'250px'}
}, "select_Card");
select_Card.startup();
});
});
请告知谢谢Clement
您好，我一直在编码，到目前为止，在WinXP中的Delphi 2007中开发和编译没有问题，直到Win7中的Delphi XE7。
我不知道为什么会这样。
错误指向的行
....
if(tS<>'') then
begin
Result:=StrToFloat(StringReplace(String(tS),'.',DecimalSeparator,[]));
Invalid:=False;
end;
....
错误：
1) [dcc32 Error] UtilNumString.pas(321): E2003 Undeclared identifier: 'DecimalSeparator'
2) [dcc32 Error] UtilNumString.pas(321): E2250 There is no overloaded version of 'StringReplace' that can be called with these arguments
请亲指教。谢谢
从Win XP下的Winphi 2007到Win7下的Xe7,
我不确定为什么这个突出显示的行不起作用
Error : [dcc32 Error] utilmemblock.pas(935): E2017 Pointer type required
//D:Convert a memory block to a List. Odd sizes are truncated.
procedure MemBlockToList(const MemBlock:TMemBlock;List:TList);
var
Size:Integer;
begin
Size:=(MemBlock.Size div SizeOf(Pointer));
List.Count:=Size;
Move(MemBlock.Block^,List.Last^,Size*SizeOf(Pointer)); // This error points to this line
end;
我已经检查了这个相关的问题,但我无法弄清楚如何将它应用于我的问题.
我跟着Delphi Basic的一个例子.我复制了它,能够在我的Delphi 2007中运行得很好.
所以我构建了自己的程序并使用了上面提到的这种方法但是遇到了错误.错误声明"...引发异常类EConvertError with message"9.702827253E + 003'不是有效的浮点值".
抓我的头......
var
readResult2:WideString;
strSN:String;
strSN2:String;
floatSN:Extended;
何时readResult2被读作'+ 9.702827253E + 003'#$ A,如手表所示,
strSN := readResult2;
Delete(strSN,1,1);
floatSN := StrToFloat(strSN); //This line created an error
freqSformat.Text := FloatToStr(floatSN);
知道为什么会这样吗？我还是难过......
