Hello,
i have some oracle API by which i am able to generate web pages with some stats displayed by charts which can be viewed by the end clients.
But i am having trouble with one JS method which is being used for the dynamic update of the type of the chart.
I get “[B]v_embed_object is null or not an object
[CODE]<SCRIPT LANGUAGE=”JavaScript”>
function changeGraphType(p_graph_id,p_type){
v_value_url = “MyTestCharts.swf?p_chart_code=”+p_type;
v_chart_object = document.getElementById(p_graph_id);
v_movie_object = document.getElementById(“movie_”+p_graph_id);
v_embed_object = document.getElementById(“embed_”+p_graph_id);
v_movie_object.setAttribute(“value”,v_value_url);
v_embed_object.setAttribute(“src”,v_value_url);
}
</script>
I think it is quite obvious error for an expert but i am the complete newbie in JS.. ?
to make things simplier i can provide the full code of the generated page:
[CODE]

<BODY>
<SCRIPT LANGUAGE=”JavaScript”>
function changeGraphType(p_graph_id,p_type){
v_value_url = “MyTestCharts.swf?p_chart_code=”+p_type;
v_chart_object = document.getElementById(p_graph_id);
v_movie_object = document.getElementById(“movie_”+p_graph_id);
v_embed_object = document.getElementById(“embed_”+p_graph_id);
v_movie_object.setAttribute(“value”,v_value_url);
v_embed_object.setAttribute(“src”,v_value_url);
}
