应用程序中的手风琴

参考 this 模板。它有手风琴展开/不展开的例子。

总的来说,您需要绑定以下内容 onAttach 事件。

  widget.styles = ['collapsed'];
  widget.getElement().removeAttribute('aria-expanded'); 

绑定 toggleAccordionRow 方法 onClick() 事件,

/**
 * Expands an accordion row. 
 * Extends default functionality of the Accordion widget.
 * @param {Widget} accordionRow - accordion row which was clicked.
 */
function expandAccordionRow(accordionRow) {
  var rows = accordionRow.parent.children._values;

  var i = 0;
  for (i = 0; i < rows.length; i++) {
    if (rows[i].name.indexOf('YourElementName') > -1) {
      rows[i].styles = [];
    } else {
      rows[i].styles = ['collapsed'];
    }
  }
  accordionRow.styles = [];
}


/**
 * Collapses an accordion row. 
 * Extends default functionality of the Accordion widget.
 * @param {Widget} accordionRow - accordion row which was clicked.
 */
function collapseAccordionRow(accordionRow) {
  var rows = accordionRow.parent.children._values;

  var i = 0;
  accordionRow.styles = ['collapsed'];

  for (i = 0; i < rows.length; i++) {
    if (rows[i].name.indexOf('YourElementName') > -1) {
      rows[i].styles = ['hidden'];
    }
  }
}


/**
 * Toggles the appearance of an accordion row. 
 * Extends default functionality of the Accordion widget.
 * @param {Widget} accordionRow - accordion row which was clicked.
 */
function toggleAccordionRow(accordionRow) {
  if (accordionRow.styles.length === 0) {
    collapseAccordionRow(accordionRow);
  } else {
    expandAccordionRow(accordionRow);
  }
}
