i was trying to figure a way to bind some values as object to an element
It works if i do binding like this
var viewModel = {
someObj: ko.observable(),
textBox: {
value: ko.observable('val'),
attr: { title: 'Test', placeholder: 'Test' },
style: { width: '100px' }
}
}
<input type="text" data-bind="value: textBox.value, attr: textBox.attr, style: textBox.style />
But is there any way to bind like this
<input type="text" data-bind="bindFrom: textBox" />
I tried to create a customBinding "bindFrom" using ko.bindingHandlers but dont know how to trigger these individual bindings manually.
Looking for some help!.
Thanks in advance.
after reading knockout.debug.js
i have created this custom binding
ko.bindingHandlers.bindFrom = {
init: function (element, valueAccessor, allBindings) {
var value = ko.utils.unwrapObservable(valueAccessor()) || {};
ko.utils.objectForEach(value, function (bindName, bindValue) {
bindObj = ko.bindingHandlers[bindName];
ko.utils.objectForEach(bindObj, function (type, fn) {
if (typeof fn == 'function')
fn(element, function () { return bindValue }, allBindings);
});
});
}
};
which is working fine like expected.
