设置openlayers弹出窗口大小的正确方法是什么？

Question

我使用以下函数来设置弹出窗口的大小。但是，我注意到弹出窗口的大小总是超过我设置的大小，左边有右边距（见下文）。

我的代码有问题吗？

function onFeatureSelect(feature) {

    selectedFeature = feature;
    mydescription='<a href="' + feature.attributes.path + '">' + '<div class="visual">' + feature.attributes.image + '</div>' + '<div class="textual"><h2 class="title">' + feature.attributes.title + '</h2>' +'<div class="description">' + feature.attributes.description + '</div></div></a>';
    popup = new OpenLayers.Popup.FramedCloud("chicken",
    feature.geometry.getBounds().getCenterLonLat(),
    new OpenLayers.Size(500,300), mydescription , null, true, onPopupClose);
    popup.autoSize = true;
    popup.panMapIfOutOfView = false;
    feature.popup = popup;
    map.addPopup(popup);
}

Answer 1

只需设置popup.autoSize = false;，弹出窗口将为500px X 300px
