That service should acc…
function ajaxRequest(){
return new XMLHttpRequest(async=false);
}
function mltest (){
var filename = window.location.href.substr(window.location.href.lastIndexOf("/")+1);
MathJax.Hub.Config({TeX: {noUndefined: {disabled: true}}});
MathJax.Hub.Queue(function() {console.log('finished rendering');});
MathJax.Hub.Register.MessageHook("TeX Jax - parse error",function (message) {
console.log('error encountered');
var mydata = {};
var myrequest = new ajaxRequest();
mydata['message'] = message[1];
mydata['source'] = message[2];
mydata['mode'] = message[3] ? "display mode" : "inline";
mydata['filename'] = filename;
myrequest.open('POST', 'service/mathmltest');
myrequest.setRequestHeader("Content-type", "application/text");
myrequest.send(JSON.stringify(mydata));
});
};
mltest();
