Add a picture to each Radio Button in Radio Button Group

问题

I want to implement a Radio Button Group where every Radio Button will have a picture next to it (on the left side of the radio button).

Is that possible? If so, how?

html:

<div class="form-group" show-errors>
    <label class="col-md-2 control-label metric-light-16-black pay-form-label">Payment Method</label>
    <div class="col-md-10" id="rdPaymentMethod">
        <label class="radio-group col-md-2">
            <span id="radio-group-1" style="margin-left: 0cm;"></span>
            <span class="radio" style="margin-left: 0cm;" />
            <img src="assets/images/card-mastercard.png" style="margin-left: 0cm;"/>

        </label>

        <label class="radio-group col-md-2">
            <span id="radio-group-2" style="margin-left: 0cm;"></span>
            <span class="radio"/>
            <img src="assets/images/card-viza.png"/>
        </label>

        <label class="radio-group col-md-2">
            <span id="radio-group-3" style="margin-left: 0cm;"></span>
            <span class="radio"/>
            <img src="assets/images/card-paypal.png"/>
        </label>
    </div>
</div>

javascript sap function:

var placeRadioButtonAt = function(radioButtonId, containingDivId, selected) {
    elements.push(radioButtonId);
    var oRB1 = new sap.ui.commons.RadioButton(radioButtonId, {
        selected : (selected==true),
        select : function() {}
    });

    oRB1.placeAt(containingDivId);
}

calling this function 3 time (for each radio button):

    placeRadioButtonAt("radio1","radio-group-1",true);
    placeRadioButtonAt("radio2","radio-group-2");
    placeRadioButtonAt("radio3","radio-group-3");

回答1:

I would extend the RadioButton control for allowing images to be added with each radio button, and also extend the RadioButtonGroup to allow adding the previous extended control as an aggregation.

OBS: css classes rendering are missing, more details on renderer implementation can be found here.

Assumptions:

1. The namespace was defined as my.app inside the index.html file
2. Inside your project folder (webapp or WebContents) you have created a folder for these custom controls, named controls

RadioButton extension

sap.ui.define(['jquery.sap.global', 'sap/m/Image', 'sap/m/RadioButton'

], function (jQuery, Image, RadioButton) {
    "use strict";

    var CustomRadioButton = RadioButton.extend("my.app.controls.RadioButtonImage", {
        metadata: {
            "properties": {
                "imageSrc": "string"
            },
        },
        renderer: function (oRm, oControl) {
            var oImg = new Image({ src: oControl.getProperty("imageSrc") })
            oRm.renderControl(oImg);
            sap.m.RadioButtonRenderer.render(oRm,oControl);
        }
    });

    return CustomRadioButton;
}, true);

RadioButtonGroup extension

sap.ui.define(['jquery.sap.global', 'sap/m/RadioButtonGroup'

], function (jQuery, RadioButtonGroup) {
    "use strict";

    var CustomRadioButtonGroup = RadioButtonGroup.extend("my.app.controls.RadioButtonGroup", {
        metadata: {
            aggregations: {
                buttons : {type : "my.app.controls.RadioButtonImage", multiple : true, singularName : "button", bindable : "bindable"}
            },
            defaultAggregation : "buttons",
        }
    });

    return CustomRadioButtonGroup;
}, true);
