html - Edit webpage with javascript trick - how to "unedit"? -


i can use following scriptlet make webpage editable

javascript:document.body.contenteditable='true'; document.designmode='on'; void 0

but after doing edits want (e.g., screenshot manual), how restore state of page normal uneditable state? have tried changing true , 0 false , 1 respectively, no avail.

you need remove contenteditable attribute.

var demo_editable = document.getelementbyid('demo-editable');  var demo_button = document.getelementbyid('demo-button');    demo_editable.setattribute('contenteditable',true);    demo_button.onclick = function() {    delete demo_editable.removeattribute('contenteditable');  }
<div id="demo-editable">this editable</div><button id="demo-button">make not editable</button>

or can set attribute false.

var demo_editable = document.getelementbyid('demo-editable');  var demo_button = document.getelementbyid('demo-button');    demo_editable.setattribute('contenteditable',true);    demo_button.onclick = function() {    delete demo_editable.setattribute('contenteditable',false);  }
<div id="demo-editable">this editable</div><button id="demo-button">make not editable</button>

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
