我想创建函数时，我把任何输入（我有6)，将显示一个按钮搜索，当字段为空，相同的按钮将被隐藏。现在，我的问题是，当我写的时候，我得到了我在file.js和.jsp中声明的两个按钮（搜索并继续）。
我想要一个帮助只为这两个表达式：
<div class="button-row">
<button class="btn btn-black" type="submit" name="search"><spring:theme code="multilogin.search.button"/></button>
</div>
而且
<div class="button-row">
<button class="btn btn-black" type="button" name="multiLogin"><spring:theme code="multilogin.button.login"/></button>
</div>
您可以在这里找到代码-->https://jsfidle.net/fm1y5c8v/1/
null
inputField: function(){
// $("#multiLogin-search input").on('input', function(){
var showHideButtonSearch = () => {
let hasValue = false;
$("#multiLogin-search input.text-input").each(function(){
if ($(this).val()) {
hasValue = true;
}
});
if (hasValue === false) {
$(".button-row").hide();
} else {
$(".button-row").show();
}
}
// Check input values on key up
$("#multiLogin-search input.text-input").keyup(function() {
showHideButtonSearch();
});
//Hide button search on page load
showHideButtonSearch();
// });

thnx,
你可以那样做
if (hasValue === false) {
$('button[name=search]').parent().hide();
} else {
$('button[name=search]').parent().show();
}
