SAPUI5 and dynamic URL for OData service

1.8k views Asked by Rebecca Sikati At 24 November 2014 at 17:06

I am doing sample example using sapui5. I want to pass URL service dynamically and load ODATA service, but I really new with sapui5 and I don’t know how to do it. This code below is what i tried to do but it is not working. Thanks a lot for your help.

createContent : function(oController) {
    var oLayout = new sap.ui.commons.layout.AbsoluteLayout({width:"340px",height:"150px"});
    oLayout.addStyleClass("CustomStyle"); //Add some additional styling for the border


    var oLabel = new sap.ui.commons.Label({text:"Service Url"});
    var oUrlInput = new sap.ui.commons.TextField({width:"190px"});
    oLabel.setLabelFor(oUrlInput);
    oLayout.addContent(oLabel, {right:"248px",top:"20px"});
    oLayout.addContent(oUrlInput, {left:"110px",top:"20px"});


var oLabel = new sap.ui.commons.Label({text:"Service"});
    var oSvcInput = new sap.ui.commons.TextField({width:"190px"});
    oLabel.setLabelFor(oSvcInput);
    oLayout.addContent(oLabel, {right:"248px",top:"62px"});
    oLayout.addContent(oSvcInput, {left:"110px",top:"62px"});

    var loadData =new sap.ui.commons.Button({
        text : "load",
        width:"133px",
     press: function() {
                 oController.load();
                  }});

    oLayout.addContent(loadData, {left:"110px",top:"104px"});


    return oLayout;
}

// Controller

load: function(oEvent){


    var url = sap.ui.getControl("oUrlInput").getValue();
    var svc = sap.ui.getControl("oSvcInput").getValue();

    var oModel = new sap.ui.model.odata.OdataModel(url + "/" + svc ,false);
    var mylist = new sap.ui.model.ListBinding(oModel);
     return mylist;




}

You have to give your controls an id to access them in the controller. Like this:

// create controls with id
var oLabel = new sap.ui.commons.Label("oLabelId", {text:"Service Url"});
var oUrlInput = new sap.ui.commons.TextField("oUrlInputId", {width:"190px"});

// then to get reference to the control later
var oLabel = sap.ui.getCore().byId("oLabelId");
var oUrlInput = sap.ui.getCore().byId("oUrlInputId");

Make sure, that you use the right Url:

var oModel = new sap.ui.model.odata.OdataModel("/sap/opu/odata/sap/" + svc ,false);
