Javascript 繪圖
A.統計繪圖:
來源:http://www.chartjs.org/
import: <script src="components/com_foxparsing/Chart.js-master/Chart.js"></script>
B.解決因數值過多,造成x軸labels過度擁擠無法顯示數值的問題.
來源:http://www.chartjs.org/
import: <script src="components/com_foxparsing/Chart.js-master/Chart.js"></script>
B.解決因數值過多,造成x軸labels過度擁擠無法顯示數值的問題.
ANS:找到Chart.js在大約938行的calculateXAxisSize函式.
將valueHop = Math.floor(xAxisLength/(data.labels.length-1)); 改成
valueHop = xAxisLength/(data.labels.length-1);

Linux 網路指令
A.繞回介面:
目的:有時繞回介面才能運作
指令: ifconfig lo 127.0.0.1
B.找網路介面:
dmesg | grep eth
C.查詢本機網路和外界網路連線的指令
netstat -nr
D.修改路由表:
route [add | del] [-net | -host] destination [if]
E.觀察網路介面組態
/sbin/ifconfig lo
F.測試整個TCP/IP協定模組是否能順利運作
ssh localhost

Android Eclipse 錯誤處理
(1) R cannot be resolved to a variable
在Eclipse中某一個xml檔案沒有寫好,導致語法錯誤,會導致此問題
(2)
每當過一段時間,使用Android Eclipse會產生錯誤,因為android在遠端已經通知本地需要升級,但Eclipse並沒有被同步到
需要進行兩處的更新
A.進SDK Manager:勾選SDK Platform-tools進行更新

是 八稚女最後要撞頭的瞬間 加 ac嗎?
事前需要bc 爆氣嗎?
ok 謝謝 讚
另外單放豺華之後 可以取消 接 一般必殺技吧?

Javascript 與 PHP
A.javascript轉頁post呼叫php:
HTML:
<form action='".$PHP_SELF."' method='post'>
<input type='hidden' name='filelink' id='filelink' value='say it' >
<input type='submit' name='parse' value='Parsing' >
</form>
PHP:
echo("alert('".$_REQUEST["filelink"]."');");
(一定要加上 ' 符號);
變數宣告- echo("var filelink = '".$_REQUEST["filelink"]."';");
B.PHP呼叫帶參數javascript function:
echo ("<td><input type='button' name='delete' value='delete' onclick=\"senddelete('".$row['id']."','".$row['link']."')\" > </td>");
C.上傳檔案名稱重複的重新命名:
$splitname = explode(".", $_FILES['file']['name']);
$name = $splitname[0];
$extension = $splitname[1];
$increment = 1; //start with no suffix
while(file_exists("upload/".$name .'('.$increment . ').' . $extension)) {
$increment++;
}
$newfilename = $name .'('.$increment . ').' . $extension;
D.onclick 呼叫 php
<input id="do" class="button1" type="button" name="bu2" size="3" onclick="callPHP()" value="getcon2" >
function callPHP() {
$.ajax({
type: "POST",
url: 'components/com_foxbmi/callurl.php',
data:{action:'call_this'},
success:function(html) {
alert(html);
}
});
}
E.使用PHP做post與get html source:
<?php
$postdata = http_build_query(
array(
'id' => '0123456789',
'mac' => '112233445566',
'date' => '2014/10/10 11:11:11',
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://120.126.40.58:8080/FoxLink/UpLoad/RRUpLoad', false, $context);
echo $result;
/*
$url = 'http://120.126.40.58:8080/FoxLink/UpLoad/RRUpLoad';
echo file_get_contents($url);
*/
?>
HTML:
<form action='".$PHP_SELF."' method='post'>
<input type='hidden' name='filelink' id='filelink' value='say it' >

</form>
