javascript 将array 转换成string的例子

方法1:

function(selectiones, values) {               
                    var selectionsSpecialityIDs = [];
                    var selectionsSpecialities = '';
   
                    if (!isUndefinedOrNull(selectiones)) {
                        if (selectiones.data.items.length > 0) {
                            for (var i = 0; i < selectiones.data.items.length; i++) {
   
                                // Used for WEB Service
                                selectionsSpecialityIDs.push(selectiones.data.items[i].data.ID);
   
                                // Used for view only
                                if (selectionsSpecialities != '') {
                                    selectionsSpecialities += ' / ' + selectiones.data.items[i].data.Label;
                                }
                                else selectionsSpecialities = selectiones.data.items[i].data.Label;
                            }
                        }
                    }

自己看吧 不难 selections是一个数组

方法2:

var fruits = ["Banana", "Orange", "Apple", "Mango"];
document.write(fruits.toString());
