OJET7: OJET Bindings

OJET7: OJET Bindings

2 types of Binding OJET supports
-------------------------------------------

  • KO binding
  • OJET custom binding


KO binding
-------------
Checkbox - <input type="checkbox" data-bind="checked: agreed">
Button - <button data-bind="enable:agreed">
Text - <input type="text" data-bind="value:newStudent, valueUpdate:'afterkeydown'"/>
Button - <button data-bind="click: addStudent, enable:newStudent().length > 0">
select - <select multiple data-bind="options:studentList, selectedOptions:selectedStd">
ForEach - <p> & <table>
------------------------
<p data-bind="foreach: studentList"><input name="std" type="radio" data-bind="value: $data, checked: $parent.choosenRadioStd"/></p>

<table data-bind="foreach:personList"
<td><span data-bind="text: $data.firstName">

 <!-- ko foreach:personList -->
    <span data-bind="text: $data.firstName"></span>
 <!-- /ko -->


OJET custom binding
---------------------
{{value}} - 2 way binding

[[value]] - 1 way binding

Examples:
-------------
<oj-input-text value="{{uname}}" required></oj-input-text>
<span> <oj-bind-text value="[[uname]]"></oj-bind-text>   </span>
<oj-input-date value="{{dob}}" required></oj-input-date>
<oj-button on-oj-action='[[buttonClick]]' id="mybutton"> Click Me</oj-button>
<oj-checkboxset id="checkboxSetAgreeId" labelled-by="agreeId"
                            value="{{agreement}}"
                            required >
              <oj-option id="agree" value="agree">I Agree</oj-option>
            </oj-checkboxset>
<oj-radioset id="radiosetBasicDemoId" labelled-by="mainlabelid"
                       value="{{currentColor}}" >
            <oj-option id="blueopt" value="blue">Blue</oj-option>
            <oj-option id="greenopt" value="green">Green</oj-option>
            <oj-option id="redopt" value="red">Red</oj-option>
          </oj-radioset>
