I can use jquery .contents() to get element of iframe e.g. the iframe #ours_iframe in the sample code
<iframe src="{{ url_for('t01_ours_iframe') }}" id="ours_iframe></iframe>
Though with iframe of google data studio, aka ggds, I cannot do so using .contents() ie trying to call .contents() will result as length=0 e.g. the iframe #ggdschart__div_in_iframe in the sample code
<iframe width="880" height="660" src="{{ ggds_chart_embedurl }}" frameborder="0" style="border:0" allowfullscreen id="ggdschart_iframe"></iframe>
The difference of the two can be seen by printing their .length - please refer to the full sample code here
console.log(`ggdschart__div_in_iframe.length : ${ggdschart__div_in_iframe.length}`)
console.log(`ours__div_in_iframe.length : ${ours__div_in_iframe.length}`) //NOTE while we CAN get .contents() here normally ie .length = 7
My google search and search right on our stackoverflow site resulted with little helpful results. So my question is how to get ggds 's iframe elements using jquery?
