javascript - What does "XMLHttpRequest.timeout cannot be set for synchronous http(s) requests made from the window context" mean? -


i'm getting timeouts on synchronous xml http request in safari on mac. workaround, tried adding timeout so:

    req.open(this.method, fullurl, this.isasync);     req.setrequestheader('content-type', 'application/x-www-form-urlencoded');      var params = this.envelopeform();     req.setrequestheader("content-length", params.length);     req.timeout = 60000;  //get timeut cannot set here     req.send(params);  //without above, timeout here in safari

with .timeout = 60000 i'm getting timeout on .send.

with .timeout=60000, i'm getting "xmlhttprequest.timeout cannot set synchronous http(s) requests made window context."

i'm not clear on "xmlhttprequest.timeout cannot set synchronous http(s) requests made window context" means. found in mozilla's documentation phrased so:

note: may not use timeout synchronous requests owning window.

is there work-around this? on msdn site found following statement regarding internet explorer:

if set xmlhttprequest time-out value larger network stack's time-out value, network stack time out first , ontimeout event not raised

timeout synchronous ajax requests can used web workers

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
