javascript - HTML Dropdown set dictionary value as selected in jquery

Question

I have a HTML drop down. The data source for the drop down is a dictionary. The selected values key will be stored in a hidden field. On page reload i want to set the value in the dictionary as a selected value of drop down. The dictionary key will be stored in hidden field.

var IxCustomer = $(_this.IxCustomerHiddenFieldId).val();

$(_this.CustomerSelectId).find("option[value=" + IxCustomer  + "]").attr("selected", true);

How can i modify this.

Answer 1

这应该这样做：

$(_this.CustomerSelectId).val(IxCustomer);

设置<select>元素的值会选择相应的选项。
