javascript - 如何在悬停和点击时交换文本

Question

我在捐赠表格的顶部有一条默认消息，我希望它根据用户悬停或点击的数量动态变化。

每个金额以及“€其他”都应该有相应的消息。例如:“用 5.00 欧元，我们可以做到这一点……”用 10.00 欧元，我们可以做到这一点……”

这些消息应该在悬停时相应地改变，但如果选择了相应的选项，它们也会保持可见。

如果用户取消选择之前选择的选项或者没有选择任何选项，则默认消息应该重新出现。

我已经尝试了不同的方法但没有成功，我真的很感激能帮助我实现这一目标。

Answer 1

大卫!最后我改进了它:)您可以通过 data-alertOnHover 在 HTML 中单独自定义您自己的消息，它在悬停在按钮或文本框上时显示，而 data-alertAfter 在显示后选择一个按钮或在文本框中键入一个数字。它涵盖了所有状态并且不那么繁琐。

还有

if the user deselects a previously selected option or if no option is selected, the default message will reappear.

var defaultTxt = $('#alert').text();
var checked;
$('input.checkbutton').change(function() {
  if ($(this).is(":checked")) {
    $(".textBox").val("");
  	$('#alert').text($(this).attr("data-alertAfter") + $(this).val());
    checked = $(this);
  }
  else
  {
  	$('#alert').text(defaultTxt);
    checked = undefined;
  }
  $('input.checkbutton').not(this).prop('checked', false);
});
$('.input-container').hover(
  function() {
    $('#alert').text($(this).children('input').attr("data-alertOnHover"));
  },
  function() {
    if (checked)
    	$('#alert').text($(checked).attr("data-alertAfter") + $(checked).val());
    else
    	$('#alert').text(defaultTxt);
  }
);
$(".textBox").focus(function() {
  checked = undefined;
	$(".checkbutton").prop("checked", false)
}).blur(function() {
  if ($(this).val() != "") {
  	checked = $(this);
  	$('#alert').text($(this).attr("data-alertAfter") + $(this).val())
  }
});
