jquery code:

Copy code The code is as follows:

$(document).ready(function(){
$("#repTable span.address").each(function(){
var spanTemp = $(this);
$ .ajax({
type: "get",
url: "SceneryAjaxCall.aspx",
data: "sid=" $(this).attr("id"),
cache: true,
dataType: "html",
success: function(msg){
spanTemp.append(msg);
}
});
});
});


When writing jquery code, I encountered the following problems:

(1) I did not write the third line at the beginning, but at the beginning. In line 11, $(this) is directly called, and the error "Cannot assign a value to the callback function" is reported. The reason is that the object has changed after the callback, so it needs to be saved in advance;

(2) The dataType is not written, and msg cannot be returned. I don’t know why;
