如何在Trix编辑器中自动链接URL

问题描述

当我们将内容粘贴到trix-editor中时，href不会粘贴为简单文本。我们如何使其成为链接。

解决方法

    var TrixAutoLinker,bind = function(fn,me){ return function(){ return fn.apply(me,arguments); }; };

addEventListener("trix-initialize",function(event) {
  return new TrixAutoLinker(event.target);
});

TrixAutoLinker = (function() {
  var INPUT,PATTERN,isValidURL;

  function TrixAutoLinker(element) {
    this.element = element;
    this.autoLink = bind(this.autoLink,this);
    this.editor = this.element.editor;
    this.element.addEventListener("trix-render",this.autoLink);
    this.autoLink();
  }

  TrixAutoLinker.prototype.autoLink = function() {
    var currentRange,i,len,range,ref,ref1,results1,url;
    ref = this.getURLsWithRanges();
    results1 = [];
    for (i = 0,len = ref.length; i < len; i++) {
      ref1 = ref[i],url = ref1.url,range = ref1.range;
      if (this.getHrefAtRange(range) !== url) {
        currentRange = this.editor.getSelectedRange();
        this.editor.setSelectedRange(range);
        if (this.editor.canActivateAttribute("href")) {
          this.editor.activateAttribute("href",url);
        }
        results1.push(this.editor.setSelectedRange(currentRange));
      } else {
        results1.push(void 0);
      }
    }
    return results1;
  };

  TrixAutoLinker.prototype.getDocument = function() {
    return this.editor.getDocument();
  };

  TrixAutoLinker.prototype.getDocumentString = function() {
    return this.getDocument().toString();
  };

  TrixAutoLinker.prototype.getHrefAtRange = function(range) {
    return this.getDocument().getCommonAttributesAtRange(range).href;
  };

  PATTERN = /(https?:\/\/\S+\.\S+)\s/ig;

  TrixAutoLinker.prototype.getURLsWithRanges = function() {
    var match,position,results,string,url;
    results = [];
    string = this.getDocumentString();
    while (match = PATTERN.exec(string)) {
      url = match[1];
      if (isValidURL(url)) {
        position = match.index;
        range = [position,position + url.length];
        results.push({
          url: url,range: range
        });
      }
    }
    return results;
  };

  INPUT = document.createElement("input");

  INPUT.type = "url";

  INPUT.required = true;

  isValidURL = function(value) {
    INPUT.value = value;
    return INPUT.checkValidity();
  };

  return TrixAutoLinker;

})();
