🛖Opentip

Opentip

js配置一下即可

• 可以配置target元素，就会在target目标元素周围显示了。
• 常用来做表单提交错误提示

javascript">var myOpentip = new Opentip($("#element"));

myOpentip.show(); // Shows the tooltip immediately
myOpentip.hide(); // Hides the tooltip immediately
myOpentip.prepareToShow(); // Shows the tooltip after the given delays. This could get interrupted
myOpentip.prepareToHide(); // ...

myOpentip.deactivate();
myOpentip.activate();

myOpentip.setContent("New content"); // Updates Opentips content

javascript">// 表单提交提示
$(function() {
  // Start when document loaded
  var myInput = $("#my-input");
  var inputOpentip = new Opentip(myInput, { showOn: null, style: 'alert' });

  // Hide the tooltip on focus so we don't bother the user while editing.
  myInput.focus(function() { inputOpentip.hide(); });
  myInput.change(function() {
    if (myInput.val()) {
      // Everything fine
      inputOpentip.hide();
    }
    else {
      // Oh oh
      inputOpentip.setContent("Please fill out this field.");
      inputOpentip.show();
    }
  });

});
