SPJS Charts - Dynamically Select Filter Item
I've been using SPJS charts to make google charts with data from sharepoint lists. If you use a custom drop-down filter, you may want to dynamically select items in the drop-down like I did.An example: You're using a drop-filter which filters the results by week, but you always want it to select last week.
Snippet:
function manualLoad(){
loadManually = false;
spjs_GenerateChart();
Date.prototype.getWeek = function() {
var onejan = new Date(this.getFullYear(),0,1);
var today = new Date(this.getFullYear(),this.getMonth(),this.getDate());
var dayOfYear = ((today - onejan + 1)/86400000);
return Math.ceil(dayOfYear/7)
};
$("#MyChart1_CustomFilterSelect_Week").val(new Date().getWeek()-1).change();
}
