看代码

var selects = $tableLeft.bootstrapTable('getSelections');
var newSelects = $.parseJSON(JSON.stringify(selects));

var selects = $tableLeft.bootstrapTable('getSelections'); //获取表选择的行

var newSelects = $.parseJSON(JSON.stringify(selects));//将获取的行转化为json对象，注意selects，而不是selects[0]

可以将此对象直接添加到Bootstrap-Table中 $tableRight.bootstrapTable("append", newSelects[0]);
