隐藏和显示基于一个下拉的值表的行 - jQuery的

Question

1. 现在的表是动态的，所以很多行能来，但下拉是静态
2. 下拉第2个和第3个值苹果和Orange只能来表第2列和下拉4日和5日值“食”和“烂”只可能在第4列
3. 所有的代码应该在功能viewChange（）现在

在当Apple被选中所有具有第二列值的行与苹果将显示等等。

选择 - 全部将再次显示整个表格

如何编写函数？

function ViewChange() 
 
{ 
 

 
var selectedViewName = $('#dropDown :selected').val(); 
 
    switch (selectedViewName) 
 
    { 
 

 
     
 

 
     case("1"): 
 
      selectedViewName="ALL"; 
 
      break; 
 
     case("2"): 
 
      selectedViewName = "Apple"; 
 
      break; 
 
     case("3"): 
 
      selectedViewName = "Orange"; 
 
      break; 
 
     case("4"): 
 
      selectedViewName = "Fresh"; 
 
      break 
 
     case("5"): 
 
      selectedViewName = "Rotten"; 
 
      break 
 

 
}

<select id="dropDown" onchange="ViewChange()"><option value="1">All</option> 
 
    <option value="2">Apple</option> 
 
    <option value="3">Orange</option> 
 
    <option value="4">Fresh</option> 
 
    <option value="5">Rotten</option> 
 
</select> 
 

 
<table id="tableID"> 
 
    <thead> 
 
    <tr> 
 
     <th>Name</th> 
 
     <th>Fruit type</th> 
 
     <th>place</th> 
 
     <th>state</th> 
 
    </tr> 
 
    </thead> 
 
    <tbody>

function ViewChange($this) { 
 
    var $selectText = $('option:selected', $this).text().toLowerCase(); 
 
    var $val = $($this).val(); 
 

 
    if ($selectText != 'all') { 
 
     $('tr').each(function() { 
 
      if ($(this).find('td').length) { 
 
       var txt = ''; 
 
       if ($val < 4) 
 
        txt = $(this).find('td:eq(1)').text().toLowerCase(); 
 
       else 
 
        txt = $(this).find('td:eq(3)').text().toLowerCase();

Answer 2

至于你问，我加入了一个多解决方案，其中有你的HTML没有变化。

解决方法1：如果没有在HTML

document.getElementById("dropDown").addEventListener("change", viewChange) 
 

 
function viewChange() 
 
{ 
 
    var value = $('#dropDown :selected').text(); 
 
    if(value=="All"){ 
 
    \t $("#tableID tbody tr").removeClass("hiddenItem"); 
 
    } else { 
 
    \t $("#tableID tbody tr").addClass("hiddenItem"); 
 
    
 
    \t $("#tableID tbody tr td").each(function (key, tdElem) { 
 
    \t \t 
 
    \t \t if(tdElem.innerHTML.toLocaleUpperCase() == value.toLocaleUpperCase()){ 
 
        \t $(tdElem.parentElement).removeClass("hiddenItem"); 
 
     \t \t } 
 
     }); 
 
    } 
 
}

.hiddenItem { 
 
    display : none; 
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<select id="dropDown"><option value="1">All</option> 
 
<option value="2">Apple</option> 
 
<option value="3">Orange</option> 
 
<option value="4">Fresh</option> 
 
<option value="5">Rotten</option> 
 
</select> 
 

 
<table id="tableID"> 
 
    <thead> 
 
     <tr> 
 
      <th>Name</th> 
 
      <th>Fruit type</th> 
 
      <th>place</th> 
 
      <th>state</th> 
 
     </tr> 
 
    </thead> 
 
    <tbody> 
 
      <tr >     
 
       <td>salim groceries</td> 
 
       <td>apple</td> 
 
       <td>nagpur</td> 
 
       <td>Fresh</td> 
 
      </tr> 
 
      <tr > 
 
       <td>monalisa groceries</td> 
 
       <td>Apple</td> 
 
       <td>Belapur</td> 
 
       <td>Rotten</td> 
 
      </tr> 
 
      <tr > 
 
       <td>taj groceries</td> 
 
       <td>Orange</td> 
 
       <td>Nasik</td> 
 
       <td>Fresh</td> 
 
      </tr> 
 
      <tr > 
 
       <td>suraj groceries</td> 
 
       <td>Orange</td> 
 
       <td>Goa</td> 
 
       <td>Rotten</td> 
 
      </tr> 
 
    </tbody> 
 

 
</table>

变化解决方案2：随着HTML变化

试试这个，它的工作原理

document.getElementById("dropDown").addEventListener("change", viewChange) 
 

 
function viewChange() 
 
{ 
 
    var value = this.value; 
 
    if(value=="All"){ 
 
    \t $("#tableID tbody tr").removeClass("hiddenItem"); 
 
    } else { 
 
    \t $("#tableID tbody tr").addClass("hiddenItem"); 
 
    \t $("#tableID tbody ." + value).removeClass("hiddenItem"); 
 
    } 
 
}

.hiddenItem { 
 
    display : none; 
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<select id="dropDown" ><option value="All">All</option>

Answer 3

请尝试以下

$.expr[":"].contains = $.expr.createPseudo(function(arg) { 
 
    return function(elem) { 
 
    return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0; 
 
    }; 
 
}); 
 
function ViewChange($this) { 
 
    var pid = $('option:selected', $this).text(); 
 
    $('#tableID tr').hide(); 
 
    $('#tableID tr > td:contains(' + pid + ')').each(function() { 
 
    $(this).parent().toggle(); 
 
    }); 
 
    if(pid == "All") { 
 
    $('#tableID tr').show(); 
 
    } else {  
 
    $('#tableID tr:first').show(); 
 
    } 
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<select id="dropDown" onchange="ViewChange(this)"><option value="1">All</option>

<option value="3">Orange</option> 
 
<option value="4">Fresh</option> 
 
<option value="5">Rotten</option> 
 
</select> 
 

 
<table id="tableID"> 
 
<thead> 
 
    <tr> 
 
    <th>Name</th> 
 
    <th>Fruit type</th> 
 
    <th>place</th>
