javascript - Prevent text selection/highlighting in a content editable div -

-

is there way create content-editable div users can't select/highlight content can still input things? want create interface users forced delete , enter things key-by-key, without being able make mass edits via highlighting.

i've looked various forms of "user-select" property in css, works static content, doesn't seem work content-editable elements/inputs.

any ideas?

thanks

if can accept textarea instead of contenteditable div, can this:

window.onload = function () {     var div = document.getelementbyid('div');     if (div.attachevent) {         div.attachevent('onselectstart', function (e) {             e.returnvalue = false;             return false;         });         div.attachevent('onpaste', function (e) {             e.returnvalue = false;             return false;         });     } else {         div.addeventlistener('paste', function (e) {             e.preventdefault();         });         div.addeventlistener('select', function (e) {             var start = this.selectionstart,                 end = this.selectionend;             if (this.selectiondirection === 'forward') {                 this.setselectionrange(end, end);             } else {                 this.setselectionrange(start, start);             }         });     } };

html:

<form>     <textarea id="div"></textarea> </form>

a live demo @ jsfiddle.

some observations on code:

  • in many browsers onselect fired input or textarea elements within form. reason different html yours.
  • ie9 - 10 don't support selectiondirection, that's why ie's legacy event handling model used these browsers.
  • if not ie, still can replace bunch of text selecting mouse , hitting key without releasing mouse button. suppose prevented detecting if mouse button down, , in case preventing keyboard actions. homework ; ).
  • the code ie works contenteditable divs too.

edit

looks i've done your "homework" too.

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
