After you click the hyperlink "set as primary entity", the original prompt box will change color and the content will be displayed: "already set as merged primary entity ".
Problem: when there is another hot zone B under the hyperlink in the prompt box of a hot zone, clicking the hyperlink in the prompt box of a hot zone will trigger the mouseover event in the B hot zone, the prompt box in the hot zone disappears.
I had a hard time thinking about this problem and couldn't find a solution. Last week, Zhou Jun asked me to check the source element of the event. I suddenly thought that the IE event object had a property fromElement. After testing it, after clicking the hyperlink in the hotspot prompt box, the fromElement in the mouseover event in the B hotspot is null, in this way, in the function that displays the prompt box of the hot zone, you can determine whether a fromElement is null. If it is null, return. Now the problem is solved, although this fromElement only exists in the event of IE.
