Anyone who has used the Google map API should notice that the JS script in the example is normal in FF, opera,... (non-IE6 browsers). An error will be reported in IE6:
Object missing
The Wrong row number generally points to the row created by the gmap2 object.
There are two solutions:
1. Specify charset = UTF-8 in Meta. For the reason, refer to Google.
2. What if charset in the application is not UTF-8? The solution is as follows:
To use the map API on a website, we need to reference a JS file. Here we can try to add a charset attribute in the script attribute.
<Script... charset = "UTF-8"> </SCRIPT>
Below are some examples
The map key used is
