Running Javascript on top of window.open() window -


say opening webpage (www.facebook.com) passing url window.open() function. window opens new browser since have used "_blank" in window.open() function.

i want run own javascript on newly opened window. when researched, found solution have added in source code posted below. unfortunately javascript not working on newly opened window. me in ?

<!doctype html>  <html>  <head>  <script>    	function myfunction() {  		var url = document.getelementbyid("mytext").value  		var newwindow = window.open(url,'_blank','height=400,width=600,left=10,top=10,scrollbars=yes,menubar=yes,titlebar=yes')  		var newscript = newwindow.document.createelement('script');  		//console.log(newscript);  		newscript.setattribute('type','text/javascript');  		newscript.setattribute('src','c:/users/30216/desktop/jquery_edited_new1.js');  		newwindow.document.getelementsbytagname("head")[0].appendchild(newscript);  		//console.log(newwindow);  		//newwindow.document.head.appendchild(newscript);  		  }  		  </script>  </head>  <body>  <table align = "center">  <frame>  <tr>  	<td class="url">enter url:</td>  	<td>  		<input type="text" id="mytext"></input>  	</td>  </tr>  <tr>  	<td>  		<button id="browser_open" onclick = "myfunction()">submit</button>  	</td>  </tr>  </frame>    </body>  </html>

you can access document according same-origin-policy.

if open web page facebook , webpage opened facebook.com not use same domain, protocol , port not able access document of page.

imagine you if without policy. e.g. able open facebook, secretly install key logger , tell user log in.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
