Javascript 如何在没有标记ID的情况下设置此元素输入'；s

5输入类型，无标签ID；如果我点击输入提示命令将出现，并说输入您的姓名？；输入名称后，如何对jquery“This.value=person”进行编码

请帮忙。他们没有在可单击的输入上输入person=提示。

只需使用.val（）函数设置当前元素值属性

$(this).val(person);

然后删除不需要的

，这里稍微修改一下

$(document).ready(function(e){
    $("input").click(function(){
        var that=$(this);//create a reference
        var person = prompt("Please enter your name:");
        if (person) { //as per @Roko C.Buljan's suggestion
           that.val(person);   //assign its val
           //or even $(this) is fine
           that.css("background-color","green");//as per @Roko C.Buljan's suggestion
           //You can move it here in case cancel is clicked
        } 
    });
});

$(document).ready(function(e){
    $("input").click(function(){
        var that=$(this);//create a reference
        var person = prompt("Please enter your name:");
        if (person) { //as per @Roko C.Buljan's suggestion
           that.val(person);   //assign its val
           //or even $(this) is fine
           that.css("background-color","green");//as per @Roko C.Buljan's suggestion
           //You can move it here in case cancel is clicked
        } 
    });
});

正如@Roko C.Buljan所说的，是的，不是<代码>不能有结束标记。

？输入是无效元素之一，不能有结束标记。（两者都不能包含其他子元素）谢谢大家$（本）val（人）；让我的一天快乐：）

$(document).ready(function(e){
    $("input").click(function(){
        var that=$(this);//create a reference
        var person = prompt("Please enter your name:");
        if (person) { //as per @Roko C.Buljan's suggestion
           that.val(person);   //assign its val
           //or even $(this) is fine
           that.css("background-color","green");//as per @Roko C.Buljan's suggestion
           //You can move it here in case cancel is clicked
        } 
    });
});
