选择后如何保留Select2结果? [英] how to retain Select2 results after select?

问题描述

例如，使用 select2多值时，用户输入了"新"，并显示

For example, when using select2 muti-value, user entered 'new', and it showed

• 新墨西哥州
• 新罕布什尔州
• 新泽西州
• 纽约

• New Mexcio
• New Hampshire
• New Jersey
• New York

在选择" New Mexcio "之后，用户希望从剩余的3个剩余部分中再次选择.为此，用户必须再次输入"new".

After selecting 'New Mexcio', and the user would like to select again from the rest of the 3 remaining. In order to to do that, the user has to enter 'new' again.

是否可以保留结果而不是清除'查询?"

Is there a way to retain the results instead of clear out the 'query?

谢谢

推荐答案

听起来像您希望将查询从一个搜索持续到另一个搜索.您可能要签出nextSearchTerm属性.

Sounds like you want to persist a query from one search to the next. You might want to check out the nextSearchTerm property.

要在下次搜索中显示当前值，

To display the current value in the next search,

function displayCurrentValue(selectedObject, currentSearchTerm) {
  return currentSearchTerm;
}

$("#e1").select2({
  nextSearchTerm: displayCurrentValue
});
