问题描述
大家好，
我想每次使用Geocode API绘制标记时都在文本框中显示计数数量，但是文本框中什么都没有显示.
如果我每次单击按钮都在运行用于显示计数的代码，则相同的逻辑将在文本框中显示数字，但是当将相同的逻辑与地理编码API一起使用时，则不会显示计数.谁能帮我解决问题吗?
提前谢谢.
Hi all,
I want to show number of counts in the text box for ever time i plot the marker using Geocode API but nothing is showing in the text box.
If i''m running the code for showing count every time i click on button then the same logic is showing numbers in text box but when using this same logic with geocode API so its not showing count.
Can anyone please please help me how to solve it?
Thanks in advance.
