单独控制多个表

时间：2018-06-05 18:19:24

标签： jquery html html-table toolbar

我正在使用多个html表，每个表都有自己的工具栏。但是我无法单独控制每张桌子。如果查看the example，可以看到如果单击字体大小按钮或行高按钮，则会影响两个表。 我正在寻找一个解决方案，我不必为每个表都有唯一的ID。

我尝试过：

closest('element-row').find('.title')
没有任何运气。也许这是一个可能的解决方案，不确定。

jsfiddle example 

$(".line-height-btn").click(function() {
  if ($(".large-line-height").length) {
    $("td").removeClass("large-line-height").addClass("medium-line-height");
  } else if ($(".medium-line-height").length) {
    $("td").removeClass("medium-line-height").addClass("small-line-height");
  } else if ($(".small-line-height").length) {
    $("td").removeClass("small-line-height").addClass("large-line-height");
  } else {
    $("td").addClass("medium-line-height");
  }
});

$(".format-size-btn").click(function() {
  if ($(".large-font-size").length) {
    $("td").removeClass("large-font-size").addClass("medium-font-size");
  } else if ($(".medium-font-size").length) {
    $("td").removeClass("medium-font-size").addClass("small-font-size");
  } else if ($(".small-font-size").length) {
    $("td").removeClass("small-font-size").addClass("large-font-size");
  } else {
    $("td").addClass("medium-font-size");
    console.log("Hello world!");
  }
});

处理程序函数中的

let $td = $(evt.target).closest('.table-title-row').next('.table-container').find('td'); - 根据您当前的HTML结构 - 找到您想要的表格单元格。

$(".line-height-btn").on("click", function(evt) {
  let $tbody = $(evt.target).closest('.table-title-row').next('.table-container').find('tbody')[0];
  switch($tbody.className) {
  case "large-line-height":
    $tbody.className = "medium-line-height";
    break;
  case "medium-line-height":
    $tbody.className = "small-line-height";
    break;
  case "small-line-height":
    $tbody.className = "large-line-height";
    break;
  default:
    $tbody.className = "medium-line-height";
  }
});

$(".format-size-btn").on("click", function(evt) {
  let $table = $(evt.target).closest('.table-title-row').next('.table-container').find('table')[0];
  switch($table.className) {
  case "large-font-size":
    $table.className = "medium-font-size";
    break;

您可以使用以下代码：

$(".line-height-btn").click(function() {
if ($(".large-line-height").length) {
$(this).parent().parent().next().find("td").removeClass("large-line-height").addClass("medium-line-height");
} else if ($(".medium-line-height").length) {
 $(this).parent().parent().next().find("td").removeClass("medium-line-height").addClass("small-line-height");
} else if ($(".small-line-height").length) {
 $(this).parent().parent().next().find("td").removeClass("small-line-height").addClass("large-line-height");
  } else {
    $(this).parent().parent().next().find("td").addClass("medium-line-height");
     }
    });

类似地将此类逻辑应用于$（“。format-size-btn”）。click（）
