vue中根据html动态渲染内容

需求：根据数据中的html，因为我是在做填空，所以是需要将html中的_____替换成input，由于具体需求我使用的是元素contenteditable代替的可编辑的input

html部分

js部分

// 这个是为了保证输入的时候光标保持在最后
const moveCursorToEnd = (element: HTMLElement) => {
  const range = document.createRange();
  const selection = window.getSelection();

  // 找到最后一个文本节点
  let lastTextNode: Text | any = null;
  const traverseNodes = (node: Node) => {
    if (node.nodeType === Node.TEXT_NODE) {
      lastTextNode = node as Text;
    }
    for (let i = 0; i < node.childNodes.length; i++) {
      traverseNodes(node.childNodes[i]);
    }
  };
  traverseNodes(element);

  if (lastTextNode) {
    range.setStart(lastTextNode, lastTextNode.textContent?.length || 0);
    range.collapse(true);
    if (selection) {
      selection.removeAllRanges();
      selection.addRange(range);
    }
  } else {
    range.setStart(element, 0);
    range.collapse(true);
    if (selection) {
      selection.removeAllRanges();
      selection.addRange(range);
    }
  }

  // 兼容性处理：确保元素获取焦点
  element.focus();
  if (document.activeElement !== element) {
    element.focus();
  }
};

// 计算属性，用于生成渲染内容
const renderedContent = computed(() => {
  if (!itemConf.value.customConf?.inputHtml) return null;
  const parts = itemConf.value.customConf.inputHtml.split(/_{1,}/);
  let nodes: any = [];

  parts.forEach((part, index) => {
    if (part) {
      const replacedSpaces = part.replace(/ /g, ' ');
      const replacedPart = replacedSpaces.replace(/
/g, '
').replace(/<\/div>/g, '');
      nodes.push(h('span', { class: 'custom-span', innerHTML: replacedPart }));
    }
    if (index < parts.length - 1) {

我们要模拟input可清除，所以需要我们去调整样式，以及placeholder样式问题
