Suggestion to resolve jQuery dependency issue in ECharts

ECharts jQuery dependency analysis and solution suggestions

ECharts is a very popular data visualization library developed and maintained by Baidu, which can help developers quickly create All kinds of cool charts. However, the use of ECharts often involves dependency issues with the jQuery library, which may lead to conflicts or functions that cannot be used normally in some cases. This article will analyze the jQuery dependency of ECharts, propose solutions, and provide some specific code examples.

1. The impact of jQuery on ECharts

When using ECharts, you may use some features or plug-ins of jQuery, such as DOM operations, event processing, etc. Since ECharts may also use jQuery-related functions internally, if the versions are inconsistent or conflict occurs, some functions may not work properly.

2. Solution suggestions

In order to solve the jQuery dependency problem of ECharts, we can take the following solutions:

2.1 Use an independent version of jQuery

In order to avoid conflicts with the jQuery version inside ECharts, you can use an independent version of jQuery in the project. You can choose to introduce jQuery as a standalone, rather than relying directly on the jQuery that comes with ECharts.

<!DOCTYPE html>
<html>
<head>
  <script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
  <script src="https://cdn.bootcdn.net/ajax/libs/echarts/5.2.2/echarts.min.js"></script>
</head>
<body>
  <div id="chart" style="width: 600px; height: 400px;"></div>
  <script>
    // 在这里使用单独引入的jQuery
    $(document).ready(function() {
      var myChart = echarts.init(document.getElementById('chart'));
      // 做一些图表操作
    });
  </script>
</body>
</html>

2.2 Using noConflict()

If you really need to use the built-in jQuery version in ECharts, you can consider using jQuery’s noConflict() method to resolve conflicts. This avoids jQuery conflicts on a global scale, allowing ECharts and jQuery to coexist harmoniously.

  <script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
  <script src="https://cdn.bootcdn.net/ajax/libs/echarts/5.2.2/echarts.min.js"></script>
</head>
<body>
  <div id="chart" style="width: 600px; height: 400px;"></div>
  <script>
    // 使用jQuery的noConflict()方法
    var jq = jQuery.noConflict();
    jq(document).ready(function() {
      var myChart = echarts.init(document.getElementById('chart'));
      // 做一些图表操作
    });
  </script>
</body>
</html>

Copy after login
