示例1: itNoIE

  itNoIE("proper caret position for elements that span lines", () => {
    const p = editor.dataRoot.querySelectorAll("body>p")[5];

    // Check that we are testing what we want to test. The end label for the hi
    // element must be on the next line. If we don't have that condition yet,
    // we modify the document to create the condition we want.
    let textLoc: DLoc;
    let hi: Element;
    // This is extremely high on purpose. We don't want to have an arbitrarily
    // low number that will cause issues *sometimes*.
    let tries = 1000;
    let satisfied = false;
    // tslint:disable-next-line:no-constant-condition
    while (true) {
      tries--;
      textLoc = caretManager.fromDataLocation(p.lastChild!, 2)!;
      assert.equal(textLoc.node.nodeType, Node.TEXT_NODE);
      const his =
        (textLoc.node.parentNode as Element).getElementsByClassName("hi");
      hi = his[his.length - 1];
      const startRect = firstGUI(hi)!.getBoundingClientRect();
      const endRect = lastGUI(hi)!.getBoundingClientRect();

    event.clientX = left;
    event.clientY = (top + bottom) / 2;
    event.pageX = event.clientX + editor.window.document.body.scrollLeft;

    event.which = 1; // First mouse button.
    editor.$guiRoot.trigger(event);
