一、2K和4K弹窗判断

  {* 判断2k和4k弹窗 *}{if $dataScene['scene_standard'] eq 0}<a class="menuBtn subMenu" onclick="getZoomUrl('?m=Index&a=overview&act=showView&member_id={$dataScene['member_id']}', '1613px', '955px', 'no','{$dataScene['scene_name']}')">{$dataScene['scene_name']}</a>{else}<a class="menuBtn subMenu" onclick="getZoomUrl('?m=Index&a=overview&act=showView&member_id={$dataScene['member_id']}', '3226px', '1910px', 'no','{$dataScene['scene_name']}')">{$dataScene['scene_name']}</a>{/if}

 {if $dataScene neq ""}<a class="menuBtn subMenu" href="?m=Index&a=overview&act=showView&member_id={$dataScene['member_id']}">总览图</a>{/if}

二、电能API对接

1.电脑爬虫

    public function getIotPower(){global $res, $CONF;dbc();$group = $this->getGroupId();$group_id = $group["energyid"];if ($group_id && $group_id != "0") {$url = curlIotAPI($CONF["api_iot_pipe"], '1', '1000', $CONF["api_user_key"], $group_id);$reArr = json_decode($url, true);$data_int = $reArr["data"];$res["data"] = getIotPower($data_int["data"]);die(json_encode_lockdata($res));} else {$res["data"] = NULL;die(json_encode_lockdata($res));}}

2.电能分组过滤

/*物联网-电量流量分组 2023-3-23*/
function getIotPower($arr)
{@$list = array();foreach ($arr as $k => $v) {if (!isset($list[$v["device"]])) {$list[$v["device"]] = $v;} else {$list[$v["device"]]["name"] .= "," . $v["name"];$list[$v["device"]]["id"] .= "," . $v["id"];$list[$v["device"]]["sdata"] .= "," . $v["sdata"];$list[$v["device"]]["odata"]["today_val"] .= "," . $v["odata"]['today_val'];//当天$list[$v["device"]]["odata"]["current_month"] .= "," . $v["odata"]['current_month'];//当月-2023.3$list[$v["device"]]["odata"]["current_year"] .= "," . $v["odata"]['current_year'];//当年$list[$v["device"]]["odata"]["b_yesterday_val"] .= "," . $v["odata"]['b_yesterday_val'];//前天$list[$v["device"]]["odata"]["yesterday_val"] .= "," . $v["odata"]['yesterday_val'];//昨天$list[$v["device"]]["odata"]["last_month_val"] .= "," . $v["odata"]['last_month_val'];//上月-2023.2$list[$v["device"]]["odata"]["b_last_month_val"] .= "," . $v["odata"]['b_last_month_val'];//上上月-2023.1$list[$v["device"]]["odata"]["b_last_year_val"] .= "," . $v["odata"]['b_last_year_val'];//前年$list[$v["device"]]["odata"]["last_year_val"] .= "," . $v["odata"]['last_year_val'];//去年@$list[$v["device"]]["odata"]["three_days_ago_val"] .= "," . $v["odata"]['three_days_ago_val'];@$list[$v["device"]]["odata"]["three_month_ago_val"] .= "," . $v["odata"]['three_month_ago_val'];@$list[$v["device"]]["odata"]["three_years_ago_val"] .= "," . $v["odata"]['three_years_ago_val'];@$list[$v["device"]]["odata"]["four_month_ago_val"] .= "," . $v["odata"]['four_month_ago_val'];//-2022.12@$list[$v["device"]]["odata"]["five_month_ago_val"] .= "," . $v["odata"]['five_month_ago_val'];//-2022.11@$list[$v["device"]]["odata"]["six_month_ago_val"] .= "," . $v["odata"]['six_month_ago_val'];//-2022.10@$list[$v["device"]]['data']["deviceType"] .= "," . $v['data']["deviceType"];$list[$v["device"]]['data']["measure_unit_type"] .= "," . $v['data']["measure_unit_type"];$list[$v["device"]]['data']["propertyType"] .= "," . $v['data']["propertyType"];$list[$v["device"]]['data']["sensorStatus"] .= "," . $v['data']["sensorStatus"];}}return array_values($list);
}

在 PHP 中，@ 符号被称为错误抑制操作符。当在表达式之前使用 @ 符号时，它会告诉 PHP 忽略该表达式可能产生的任何错误或警告消息。

使用 @ 符号的主要目的是在运行时隐藏错误消息，以防止它们显示在最终的用户界面上。然而，过度使用错误抑制符可能会导致问题的隐藏和调试难题，因此它的使用应当谨慎。

需要注意的是，虽然 @ 符号可以抑制错误消息的显示，但它不会阻止代码中的错误和异常。错误实际上仍然存在，只是被隐藏起来。这意味着当代码中存在错误时，它们仍然会对程序的执行和结果产生影响。

因此，建议在编写 PHP 代码时，避免过度依赖 @ 符号来掩盖错误。而是应该使用适当的错误处理和异常处理机制来捕获和处理错误，以便更好地调试和修复问题。

3.数据可视化渲染

/** 电能流量环境状态*半年* */
function getYearPower() {$.when($.getJSON('api/api.php?act=getIotPower&token=3cab7ce4142608c0f40c785b5ab5ca24')).done(function (res1) {var data2 = res1.data.sort(getSortFun('asc', 'device_seq'));//console.log(data2);if (data2) {var flow_entHtml = "";var lightStatus = [];for (var d = 0; d < data2.length; d++) {var sensor = data2[d].data.propertyType;var lastvalue = data2[d].sdata;var sta = data2[d].data.sensorStatus;var norm = sensor.split(",");var normValue = lastvalue.split(",");var staValue = sta.split(",");var yesVal = data2[d].odata.yesterday_val.split(",");var last_month = data2[d].odata.last_month_val.split(",");var last_year = data2[d].odata.last_year_val.split(",");lightStatus[d] = data2[d].data.sensorStatus;//新增当日/月/年数据 2022.07.23 BY poleung;var today_val = data2[d].odata.today_val.split(",");var current_month = data2[d].odata.current_month.split(",");var current_year = data2[d].odata.current_year.split(",");//console.log(yesterdayValue);//数据排序，防止错乱;var normT = [], statusT = [];for (var i = 0; i < norm.length; i++) {//今日电量;if (norm.indexOf("电量") == -1) {normT[0] = "-";statusT[0] = "无设备";} else {if (norm[i] == "电量") {//normT[0] = parseFloat(normValue[i] - yesVal[i]).toFixed(1);normT[0] = getPositive(parseFloat(today_val[i] - yesVal[i]).toFixed(1));statusT[0] = staValue[i];}}//本月电量;if (norm.indexOf("电量") == -1) {normT[1] = "-";statusT[1] = "无设备";} else {if (norm[i] == "电量") {normT[1] = getPositive(parseFloat(current_month[i] - last_month[i]).toFixed(1));statusT[1] = staValue[i];}}//本年电量;if (norm.indexOf("电量") == -1) {normT[2] = "-";statusT[2] = "无设备";} else {if (norm[i] == "电量") {normT[2] = getPositive(parseFloat(current_year[i] - last_year[i]).toFixed(1));statusT[2] = staValue[i];}}if (norm.indexOf("A相电流") == -1) {normT[3] = "-";statusT[3] = "无设备";} else {if (norm[i] == "A相电流") {normT[3] = parseFloat(today_val[i]).toFixed(2);statusT[3] = staValue[i];}}if (norm.indexOf("B相电流") == -1) {normT[4] = "-";statusT[4] = "无设备";} else {if (norm[i] == "B相电流") {normT[4] = parseFloat(today_val[i]).toFixed(2);statusT[4] = staValue[i];}}if (norm.indexOf("C相电流") == -1) {normT[5] = "-";statusT[5] = "无设备";} else {if (norm[i] == "C相电流") {normT[5] = parseFloat(today_val[i]).toFixed(2);statusT[5] = staValue[i];}}if (norm.indexOf("电功率") == -1) {normT[6] = "-";statusT[6] = "无设备";} else {if (norm[i] == "电功率") {normT[6] = parseFloat(today_val[i]).toFixed(1);statusT[6] = staValue[i];}}}flow_entHtml += "<li><div class='powerNorm'><div class='power2_norm1'>" + limitWords(data2[d].device, 8) + "</div><div class='power2_norm2'>"+ "<div class='power2_1'>本月<p class='houseBg'>" + getAlertCo(statusT[1], normT[1]) + "</p></div>"+ "<div class='power2_2'>本年<p class='houseBg'>" + getAlertCo(statusT[2], normT[2]) + "</p></div>"+ "<div class='power2_3'>A相<p class='houseBg'>" + getAlertCo(statusT[3], normT[3]) + "</p></div>"+ "<div class='power2_4'>B相<p class='houseBg'>" + getAlertCo(statusT[4], normT[4]) + "</p></div>"+ "<div class='power2_5'>C相<p class='houseBg'>" + getAlertCo(statusT[5], normT[5]) + "</p></div>"+ "<div class='power2_6'>功率<p class='houseBg'>" + getAlertCo(statusT[6], normT[6]) + "</p></div>"+ "</div></div></li>";}//状态灯;//console.log(lightStatus);if (lightStatus.toString().indexOf("告警") > -1 && lightStatus.toString().indexOf("离线") > -1) {$("#power_Status").removeClass().addClass("alert1");} else if (lightStatus.toString().indexOf("告警") > -1) {$("#power_Status").removeClass().addClass("alert1");} else if (lightStatus.toString().indexOf("离线") > -1) {$("#power_Status").removeClass().addClass("alert4");} else {$("#power_Status").removeClass().addClass("alert2");}$("#power_ent").html(flow_entHtml);} else {console.log("电能流量感知状态：API INTERFACE ERROR");}}).fail(function (err) {console.log(err);});

三.数组按顺序输出

在 JavaScript 中，您可以使用循环和数组的特性来按顺序输出多组数据。具体的实现取决于您的数据结构和输出方式。以下是两种常见的方法：

方法一：使用 for 循环遍历数组并输出

var data = [[1, 2, 3],[4, 5, 6],[7, 8, 9]
];for (var i = 0; i < data.length; i++) {var currentData = data[i];console.log(currentData); // 在控制台输出当前数据组
}

上述代码中，我们使用了一个 for 循环来遍历数组 data 中的每一组数据。在循环的每一次迭代中，我们将当前数据组存储在一个变量 currentData 中，并通过 console.log() 输出到控制台。

方法二：使用 forEach 方法遍历数组并输出

var data = [[1, 2, 3],[4, 5, 6],[7, 8, 9]
];data.forEach(function(currentData) {console.log(currentData); // 在控制台输出当前数据组
});

上述代码中，我们使用数组的 forEach 方法来遍历数组 data 中的每一组数据。通过传入一个回调函数，我们可以在每次迭代中获取当前数据组，并通过 console.log() 输出到控制台。
