vue-plugin-hiprint Use in detail

vue-plugin-hiprintis a plug-in for easy use of the HiPrint printing plug-in in applications. HiPrint is a web-based printing plug-in that can implement highly customized printing functions.

Overall code description

The following isvue-plugin-hiprintDetailed instructions for use:

1. Install the plug-in:

npm install vue-plugin-hiprint

2. Introduce plug-ins and register:

import Vue from 'vue'
import HiPrint from 'vue-plugin-hiprint'
(HiPrint)

3. Use HiPrint in the component:

<template>
  <div>
    <button @click="print">Print</button>
  </div>
</template>
<script>
export default {
  methods: {
    print() {
      // Call the HiPrint plugin using this.$hiprint method      this.$({
        template: '<h1>Hello, HiPrint!</h1>',
        styles: `
          h1 {
            color: red;
          }
        `
      })
    }
  }
}
</script>

Use in component methodsthis.$Method to call the HiPrint plugin. Pass a configuration object as a parameter that contains the printed template and style.

The configuration items supported by HiPrint include:

  • template: Printed template, which can be an HTML string or a DOM element.
  • styles: The printed style can be a CSS string or an object. If it is an object, it will be automatically converted to a CSS string.
  • timeout: Printing delay time, unit is milliseconds, default is 500ms.

44. Print in the browser:

After clicking the Print button, HiPrint opens a new window in the browser and renders the printed content into it. The user can print in this window, select printer and print settings.

Note: The HiPrint plug-in relies on the HiPrint print plug-in itself, so you need to make sure that the HiPrint plug-in is properly introduced before using it.

The above arevue-plugin-hiprintDetailed instructions for use. Use this plug-in to easily implement custom printing functions in the application.

Build Visual Drag and Drop Design

The process of building a visual drag and drop design usually includes the following steps:

  • Interface design: First, you need to design a visual drag and drop design interface, including drag area, toolbar, property panel, etc. Interface design should take into account the user's operating habits and ease of use.
  • Drag and drop function implementation: Use front-end frameworks (such as React, etc.) to implement drag and drop function. You can use HTML5 drag and drop API or third-party libraries (such as, etc.) to implement drag and drop functions. By listening to drag and drop events, drag and release elements can be realized.
  • Elemental Componentization: Abstract draggable elements into components for multiplexing in the dragged area. Each component can have its own properties and styles, which can be edited and modified through the properties panel.
  • Attribute Editing: Provides an attribute panel for each draggable element, where the attributes of elements can be edited and modified. You can use forms, drop-down boxes, color selectors and other components to implement attribute editing.
  • Save and Load: Implement the function of saving and loading designs, which can save the design data to a database or local storage to restore the design the next time it is loaded.
  • Export Design: Implement the function of exporting the design into an image, PDF or other format so that users can save or share the design.
  • Responsive design: Taking into account the screen size and resolution of different devices, it is necessary to ensure that the visual drag and drop design can be displayed and operated normally on different devices.

The above are the general steps for building a visual drag and drop design. During the specific implementation process, it can be adjusted and expanded according to requirements and technical selection.

Build draggable elements

The ability to build drag-and-drop elements can be implemented using HTML5 drag-and-drop API or third-party libraries. The following is a description of how to build draggable elements using the usage and library as an example:

1. Installation and library:

npm install vue vue-draggable

2. Use in Vue components:

<template>
  <div>
    <draggable v-model="elements" :options="draggableOptions">
      <div v-for="(element, index) in elements" :key="" :style="{ left:  + 'px', top:  + 'px' }" class="draggable-element">
        {{  }}
      </div>
    </draggable>
  </div>
</template>
<script>
import draggable from 'vuedraggable';
export default {
  components: {
    draggable,
  },
  data() {
    return {
      elements: [
        { id: 1, text: 'Element 1', x: 0, y: 0 },
        { id: 2, text: 'Element 2', x: 100, y: 100 },
        { id: 3, text: 'Element 3', x: 200, y: 200 },
      ],
      draggableOptions: {
        draggable: '.draggable-element',
        onEnd: ,
      },
    };
  },
  methods: {
    onDragEnd(event) {
      const { newIndex, oldIndex } = event;
      const movedElement = (oldIndex, 1)[0];
      (newIndex, 0, movedElement);
    },
  },
};
</script>
<style>
.draggable-element {
  position: absolute;
  background-color: #f0f0f0;
  padding: 10px;
  cursor: move;
}
</style>

In the above code, we use a library to implement the function of draggable elements. In Vue components we use<draggable>Components to wrap elements that need to be dragged. passv-forInstruction traversalelementsArray, rendering each element into a draggable<div>element. We set upv-modelThe command willelementsThe array is bound in two-way to the drag component to update the position of the element during the drag. By settingoptionsAttributes, we can configure the drag behavior, such as specifying drag-able element selectors, setting the callback function at the end of drag, etc.

existonDragEndIn the method, we process the logic at the end of the drag. By getting the new and old index of the drag, we can determine that the dragged element iselementsThe position in the array has changed. We usespliceMethod removes the dragged element from its original position and inserts it to the new position.

Finally, we use CSS style to set the style of draggable elements, such as setting the position of the element, background color, etc.

The above is an example of using the library to build draggable elements. You can select appropriate libraries or methods according to specific needs and technical selection to implement the function of draggable elements.
