我想在ul-list中添加一个类(class ="bbox"),但前提是不存在类.这就是我到目前为止所拥有的.如果ul-tag中存在类,如何检查jquery？

$("ul").addClass("bbox");

我试图通过提供JSON格式数据的Web服务请求天气.我的PHP请求代码没有成功,是:

$url="http://www.worldweatheronline.com/feed/weather.ashx?q=schruns,austria&format=json&num_of_days=5&key=8f2d1ea151085304102710";
$json = file_get_contents($url);
$data = json_decode($json, TRUE);
echo $data[0]->weather->weatherIconUrl[0]->value;    

这是返回的一些数据.为简洁起见,部分细节已被截断,但保留了对象完整性:

{ "data": 
    { "current_condition": 
        [ { "cloudcover": "31",
            ... } ],  
      "request": 
        [ { "query": "Schruns, Austria",
            "type": "City" } ],
      "weather": 
        [ { "date": "2010-10-27",
            "precipMM": "0.0",
            "tempMaxC": "3",
            "tempMaxF": "38",
            "tempMinC": "-13",
            "tempMinF": "9",
            "weatherCode": "113",
            "weatherDesc": [ {"value": "Sunny" } ],
            "weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0001_sunny.png" } ],
            "winddir16Point": "N",
            "winddirDegree": "356",
            "winddirection": "N",
            "windspeedKmph": "5",
            "windspeedMiles": "3" }, 
          { "date": "2010-10-28",
            ... }, …

我想通过curl获取远程文件的最后修改日期.有谁知道这是怎么做到的吗？

有谁知道如何根据时间戳显示flot中的日期

我需要在我的数据库中存储名为'msg'的json字符串中的变量,但是我无法用$ msg = $ _POST ['msg']来捕获它.我该如何正确捕捉它？

此外,我想在网页上直接回复$ msg的内容.

我将我的网站从/ v1/etc ...目录移动到/ v2/etc ...目录,并希望在htaccess中进行永久重定向.有人能帮我吗？

我想将下面的ajax函数的响应显示给dom中的div(更新div).如何在不使用重插件的情况下完成此操作.

url: 'http://dowmian.com/xs1/getcam.php',
type: 'GET',
data: {id: <?php echo $cam_id; ?>},
success: function(responseText){
},
error: function(responseText){
}

我想舍入(0位小数)flot图的x轴上的值.x-axix显示周数.有谁知道这是怎么做到的吗？

一旦访问者移动地图，我就会尝试通过 Json 添加标记。由于某种原因， moveend 没有被捕获和/或 onClickCallback 函数没有被触发。我哪里出错了。

 google.maps.event.addListener(map, "moveend", function() {
  var bounds = this.getBounds();
  onClickCallback(map);

 });


function onClickCallback(map) {

var bounds = map.getBounds();


  // clearOverlays();



    $.getJSON( 'http://skiweather.eu/gmap4/markers/index.php', {
        swLat: bounds.getSouthWest().lat(), swLon: bounds.getSouthWest().lng(), 
        neLat: bounds.getNorthEast().lat(), neLon: bounds.getNorthEast().lng()}, function(data) { 
        $.each( data.markers, function(i, marker) {


        // Define Marker properties
        var image = new google.maps.MarkerImage(marker.smallimg,
        // This marker is 129 pixels wide by 42 pixels tall.
            new google.maps.Size(42, 42),
        // The origin for this image is 0,0.
            new google.maps.Point(0,0),

我在深色背景上绘制了一个图形,但由于轴颜色和刻度值颜色,它很难读取.如何将轴的颜色,刻度线和轴刻度值更改为白色？
