Question

我似乎无法获得一段验证码。在我的HTML页面上，我有一个单选按钮组（5个按钮，值为1-5）。在单击提交按钮时，我需要在Javascript中使用IF语句来检查是否已在组中的5个单选按钮中的一个中进行了选择。我怎么做到这一点？我写的制作单选按钮的代码是：

// Technical knowledge rating
    oLabel = new sap.ui.commons.Label({
        id : 'L-Tech',
        text : '1. Technical Knowledge' });
    var oRBG = new sap.ui.commons.RadioButtonGroup({
        id : 'RBG-Tech',
        tooltip : 'Rate the intern for Technical Knowledge (1 = Unsatisfied, 5 = Outstanding)',
        columns : 5,
        editable : true });
    var oItem = new sap.ui.core.Item({
        id : 'RB-Rate1',
        text : '1',
        tooltip : 'Unsatisfactory',
        key : '1' });
    oRBG.addItem(oItem);
    var oItem = new sap.ui.core.Item({
        id : 'RB-Rate2',
        text : '2',
        tooltip : 'Improvement Needed',
        key : '2' });
    oRBG.addItem(oItem);
    var oItem = new sap.ui.core.Item({
        id : 'RB-Rate3',
        text : '3',
        tooltip : 'Meets Expectations',
        key : '3' });
    oRBG.addItem(oItem);
    var oItem = new sap.ui.core.Item({
        id : 'RB-Rate4',
        text : '4',
        tooltip : 'Exceeds Expectations',
        key : '4' });
    oRBG.addItem(oItem);
    oItem = new sap.ui.core.Item({
        id : 'RB-Rate5',
        text : '5',
        tooltip : 'Outstanding',
        key : '5' });
    oRBG.addItem(oItem);
    oMatrix.createRow(oLabel, oRBG);        
    oLabel = new sap.ui.commons.Label({
        id : 'L-Text',
        text : 'Notes (Optional):', 
        design : sap.ui.commons.TextViewDesign.L3   });
    oCell = new sap.ui.commons.layout.MatrixLayoutCell({
        colSpan : 4 });
    oTA = new sap.ui.commons.TextArea({
        id : 'TA-Text',
        tooltip : 'Remarks',
        editable : true,
        wrapping : sap.ui.core.Wrapping.Off,
        width : '200px',
        height : '60px'
        });
    oLabel.setLabelFor(oTA);
    oCell.addContent(oTA);
    oMatrix.createRow(oLabel, oCell);

if(document.getElementById('id_of_button1').checked) {
  // radio button1 is checked
}else if(document.getElementById('id_of_button2').checked) {
  // radio button2 is checked
}
else if(document.getElementById('id_of_button3').checked) {
  // radio button3 is checked
}
else if(document.getElementById('id_of_button4').checked) {
  // radio button4 is checked
}
else if(document.getElementById('id_of_button5').checked) {
  // radio button5 is checked
