Question

尝试从元素中拆分特定文本。鉴于js工作，如何简短/简单这个js？

元素html示例：

<div id="ReviewBox">
<span>(By:) Hello</span>

<div id="ReviewBox">
 <span>By: Goodbye</span>
</div>

</div>

JS：

$('#ReviewBox span:contains("By:")').each(function(){
    $(this).html($(this).html().split("(").join(""));
    $(this).html($(this).html().split(")").join(""));
});

Answer 1

您可以使用.html(function)，也应该使用.replace()和正则表达式删除(和)

$('#ReviewBox span:contains("By:")').html(function(_, html) {
  return html.replace(/[/(\)]/g, '');
});

＆＃13;

$('#ReviewBox span:contains("By:")').html(function(_, html) {
  return html.replace(/[/(\)]/g, '');
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="ReviewBox">
  <span>(By:) Hello</span>
</div>

使用单个拆分操作/[/(\)]/g

进行应用

＆＃13;

 $('#ReviewBox span:contains("By:")').each(function(){
        $(this).html($(this).html().split(/[/(\)]/g).join(""));
        
    });

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="ReviewBox">
<span>(By:) Hello</span>

<div id="ReviewBox">
 <span>By: Goodbye</span>
</div>
 
</div>

使用正则表达式$(document).ready(function() { updateMarker(); }); var mon_lat = null; var mon_long = null; var start_lat = null; var start_long = null; function updateMarker() { // Get positions if (navigator.geolocation) { // Get current position navigator.geolocation.watchPosition( function (position) { mon_lat = +position.coords.latitude; mon_long = +position.coords.longitude; initMap(mon_lat, mon_long); } ); // Get starting position navigator.geolocation.getCurrentPosition( function (position) { start_lat = +position.coords.latitude; start_long = +position.coords.longitude; initMap(start_lat, start_long); } ); } } function initMap() { // Display the map map = new google.maps.Map(document.getElementById('map'), { center: {lat: mon_lat, lng: mon_long}, zoom: 10, mapTypeControl:false }); }

/[/(\)]/g
