I've been stumped by this issue for quite some time. When I click on a button, I wish to change the value of an attribute according to the value written by the user in a text field. To do that I execute a GET which fetch the selected attribute, then execute a POST which is supposed to change the value. The problem is, I get an error code 500 along with a message telling me I do not have the Access-Control-Allow-Origin header.
Here's my settings
And here's the script activated by my button
I'm not sure what the red strip is.Anyway, I've also tried to put "plain/text" and "text" into contentType and dataType but to no avail. When the page load, I fetch all attributes of the element "Web test" with a serie of GET. I don't see why those work while my request here doesn't.
