IE 11和const的兼容問題

說好的IE11兼容javascript中的常量類型 const 呢 ？可能並沒有完全兼容

 

項目中遇到一個問題，采用google瀏覽器訪問沒問題，在本地jetty啟動，IE11也可以正常訪問，然而當我將項目打成WAR包，放到server(linux環境)上時，

報錯如下：

console

debugger

 

代碼如下：

function equitySecTypeHandler(form, secType) {
    
    // error here    
    const COMMON_STOCK = "Common Stocks";
    const SHARES_ETF = "Listed shares / ETF without complex features";
    
    var prdRiskRating = form.getValue('prdRiskRating');
    var complexPrd = form.getValue('complexPrd');
    var derivatives = form.getValue('derivatives');
    var sfcSpecifiedJuris = form.getValue('sfcSpecifiedJuris');
    var piPrdFlag = form.getValue('piPrdFlag');
    var prdClassification = form.getValue('prdClassification');
    var equitySecType = form.getValue('equitySecType');
    
    clearExtraTab(form);
    var returnBean = new Object();
    if(secType == null) {
        return returnBean;
    }
    
    if(equitySecTypeMap[equitySecType] == COMMON_STOCK) {
        returnBean.complexPrd = 'N';
        returnBean.derivatives = 'N';
        for(var key in prdClassificationMap){
            if(prdClassificationMap[key] == SHARES_ETF) {
                returnBean.prdClassification = key;
                break;
            }
        }
        returnBean.piPrdFlag = 'N';
    }
    return returnBean;
}

 

注釋掉const語句，問題解決
