单击重置后将占位符值恢复到搜索框(Restoring placeholder value to a search box after reset has been clicked)

 我正在编辑一些带有变量的搜索框的javascript，如下所示 
 
var secondSearchTerm = $('#2nd-search').val();
 
 在HTML代码'2nd-search'中有一个占位符'输入搜索词' 
 
 我还有一个重置按钮，清除搜索，如下所示： 
 
 $("#2nd-reset-btn").on("click", function () {
   return myNetwork.resetSecondSearch();
 })
 
 我想要做的是在单击重置时让搜索框重新填充占位符。 现在，最后输入的术语仍保留在搜索框中。 
 
 关于如何编辑代码来执行此操作的任何想法？ 
 
 非常感谢！ 

I am editing some javascript that has a search box with a variable as follows
 
var secondSearchTerm = $('#2nd-search').val();
 
In the HTML code '2nd-search' has a placeholder 'Enter search term' 
 
I also have a reset button that clears the search as follows:
 
 $("#2nd-reset-btn").on("click", function () {
   return myNetwork.resetSecondSearch();
 })
 
What I would like to do is to get the search box to re-populate with the placeholder when reset is clicked. Right now the last entered term remains in the search box.
 
Any ideas on how I can edit the code to do this?
 
Many thanks!
