Answer 2

你试试这个。

alert(person.address.join(', '));

Answer 3

如果您希望 Schema::create('carts', function (Blueprint $table) { $table->increments('id'); $table->integer('product_id')->unsigned(); $table->integer('product_choice_id')->unsigned(); $table->integer('user_id')->unsigned(); $table->integer('shop_id')->unsigned(); $table->integer('qty'); $table->integer('complete')->default(0); $table->timestamps(); $table->foreign('user_id') ->references('id') ->on('users') ->onDelete('cascade') ->onUpdate('cascade'); $table->foreign('product_id') ->references('id') ->on('products') ->onDelete('cascade') ->onUpdate('cascade'); $table->foreign('shop_id') ->references('id') ->on('shops') ->onDelete('cascade') ->onUpdate('cascade'); $table->foreign('product_choice_id') ->references('id') ->on('product_choice') ->onDelete('cascade') ->onUpdate('cascade'); }); 数组的最后一个索引为组合值，只需执行...

address

Answer 4

像这样......使用数组＆＃39; join()方法。join()方法将所有数组元素连接成一个字符串。

var person = {  
address: [
    '308 Congress Street',
    'Boston',
    'Massachusetts'
]
}

alert(person.address.join(', '));//OR alert(person['address'].join(', '));
