$("#test_point_geck_info")
.html("<div id='img_1' class='img_1'>" +
"<img src = " + ROOT_PATH +
"/assets/Capture.PNG onclick=PopImage(" + ROOT_PATH +
"/assets/Capture.PNG,'xyz')" +
" style='cursor:pointer;' class=thumbnail width='100' height='100'></div>");
浏览器上的结果如下:
<img src="/assets/Capture.PNG" onclick="PopImage(/assets/Capture.PNG,'xyz')" style="cursor:pointer;" class="thumbnail" width="100" height="100">
正在调用的函数:
function PopImage(imagesrc,caption) {
var PopupImageContainer = new Image();
PopupImageContainer.src = PopupImageSRC;
setTimeout("PopupImageDisplay()",loadDelay);
}
<tr class='test_file'>
<td id=img_id><img src='"+ROOT_PATH+"/assets/arrow_black_right.png' /></td>
<td colspan=2 id=fileName>"+fileName+"</td>
</tr><span>
我需要在jQuery中单击id = fileName的td时更改图像.
如何使用jQuery 获取img标记并更改其src属性？
我想做这样的事情:
$($(this).closest("img")).attr("src")

<fcn name="lvlTwoDocExample" …我很困惑在哪里使用'.find'以及在哪里使用'where'.查询执行期间的性能是否存在差异？
示例:转换使用.find的现有查询,如下所示:
FileOrFolder.find_by_fullpath(completePath, :select=>"id") - >
FileOrFolder.where(fullpath: completePath).select(:id).first
Component.find(:first, :conditions=>["cluster_id = ? AND name = ?", cluster_id, key]) - >
Component.where(cluster_id: cluster_id, name: key).first
