knockout.js - Two way binding in knockoutjs -

i start using knockoutjs. in below code trying bind div's width in two-way.

var viewmodel = function () { this.width = ko.observable(7); }; ko.bindinghandlers.widthbinding = { init: function (element, valueaccessor, allbindingsaccessor, viewmodel) { var div = $(element); var value = valueaccessor(); var width = ko.utils.unwrapobservable(value); div[0].style['width'] = width + "px"; }, update: function (element, valueaccessor, allbindingsaccessor, viewmodel) { var value = valueaccessor(); var width = ko.utils.unwrapobservable(value); div[0].style['width'] = width + "px"; } }; $("#contentdiv").enableresize(); ko.applybindings(new viewmodel()); <input data-bind="value: width" /> <div id="contentdiv" data-bind="widthbinding : width" >

in above code have 2 ui elements, 1 text input , 1 div.and can able resize div during run time. if come in number in text input means apply div's width, working fine. @ same time if resize div during run time means width should reflect in text input. there way that?

you can utilize style binding alter width :

<input data-bind="value:width ,style : { width : width()+'px' }" />

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
