Answer 1

使用form标记应用。并通过serialize()函数获取。它显示输入字段的所有值

$(document).on('click' ,'input[type=submit]' ,function () {
  
  console.log($('form').serialize());
  
  })

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form><!---its help full to get all value.--->
<p>Nama*<br />
    <span class="wpcf7-form-control-wrap your-name">
    <input type="text" name="your-name" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required form-control" aria-required="true" aria-invalid="false" /></span> </p>
<p>Email*<br />
    <span class="wpcf7-form-control-wrap your-email">
    <input type="email" name="your-email" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email form-control" aria-required="true" aria-invalid="false" /></span> </p>
<p>Pertanyaan/Cerita*<br />
    <span class="wpcf7-form-control-wrap your-message">
    <textarea name="your-message" cols="40" rows="10" class="wpcf7-form-control wpcf7-textarea wpcf7-validates-as-required form-control" aria-required="true" aria-invalid="false"></textarea></span> </p>

<p><input type="submit" value="Send" class="wpcf7-form-control wpcf7-submit" /></p>
  </form>

Answer 2

您可以通过其use an attribute equals selector的名称属性获取元素。

library(dplyr)
library(tidyr)
gather(tmp_dat, Var, Val, Score1:Score3) %>% 
           mutate(TimeN = 'Time', Var = sub("\\D+", "", Var)) %>%
           unite(Time1, TimeN, Time, Var) %>% 
           spread(Time1, Val)
# # A tibble: 3 × 7
#   Person Time_Post_1 Time_Post_2 Time_Post_3 Time_Pre_1 Time_Pre_2 Time_Pre_3
# *  <chr>       <dbl>       <dbl>       <dbl>      <dbl>      <dbl>      <dbl>
#1   greg          79          80        84.5         80         78       84.0
#2  sally          78          78        83.0         75         74       79.5
#3    sue          82          NA          NA         81         78       84.5

在jQuery中，您可以按var name = $('[name="your-name"]').val(), email = $('[name="your-email"]').val();选择字段。

name

jQuery的：

var name = $(".your-name").val();
var email = $(".your-email").val();
