如何打開窗口後提交鏈接選擇（jQuery）

Question

所以我有一個關於火車站鏈接選擇。 人們必須選擇他們的開始站和他們的目的地。

<form action="#" id="routeform" method="GET"> 
    <select class="station" name="station"> 
    <option value="Antwerpen">Antwerpen-Centraal</option> 
    <option value="Bergen">Bergen</option> 
    <option value="Brugge">Brugge</option> 
    <option value="Brussel">Brussel</option> 
    <option value="Charleroi">Charleroi-Zuid</option> 
    <option value="DePanne">De Panne</option> 
    <option selected="selected" value="Gent">Gent-Sint-Pieters</option> 
    <option value="Hasselt">Hasselt</option> 
    <option value="Kortrijk">Kortrijk</option> 
    <option value="Leuven">Leuven</option> 
    <option value="Luik">Luik-Guillemins</option> 
    <option value="Namen">Namen</option> 
    <option value="Oostende">Oostende</option> 
    <option value="Roeselare">Roeselare</option> 
    </select> 
    <select class="series" name="series"> 
    <option value="">--</option> 
    <option value="Antwerpen" class="Gent">Antwerpen-Centraal</option> 
    <option value="Bergen" class="Gent">Bergen</option> 
    <option value="Brugge" class="Gent">Brugge</option> 
    <option value="Brussel" class="Gent">Brussel</option> 
    <option value="Charleroi" class="Gent">Charleroi-Zuid</option> 
    <option value="DePanne" class="Gent">De Panne</option> 
    <option value="Hasselt" class="Gent">Hasselt</option> 
    <option value="Kortrijk" class="Gent">Kortrijk</option> 
    <option value="Leuven" class="Gent">Leuven</option> 
    <option value="Luik" class="Gent">Luik-Guillemins</option> 
    <option value="Namen" class="Gent">Namen</option> 
    <option value="Oostende" class="Gent">Oostende</option> 
    <option value="Roeselare" class="Gent">Roeselare</option> 
    <option value="Gent" class="Antwerpen">Gent-Sint-Pieters</option> 
    <option value="Brugge" class="Kortrijk">Brugge</option> 
    <option value="Gent" class="Kortrijk">Gent-Sint-Pieters</option> 
    <option value="Roeselare" class="Kortrijk">Roeselare</option> 
    <option value="Gent" class="Brugge">Gent-Sint-Pieters</option> 
    <option value="Kortrijk" class="Brugge">Kortrijk</option> 
    <option value="Oostende" class="Brugge">Oostende</option> 
    <option value="Roeselare" class="Brugge">Roeselare</option> 
    <option value="Brugge" class="Oostende">Brugge</option> 
    <option value="Gent" class="Oostende">Gent-Sint-Pieters</option> 
    <option value="Brussel" class="Bergen">Brussel</option> 
    <option value="Gent" class="Bergen">Gent-Sint-Pieters</option> 
    <option value="Brussel" class="Namen">Brussel</option> 
    <option value="Gent" class="Namen">Gent-Sint-Pieters</option> 
    <option value="Bergen" class="Brussel">Bergen</option> 
    <option value="Charleroi" class="Brussel">Charleroi-Zuid</option> 
    <option value="Gent" class="Brussel">Gent-Sint-Pieters</option> 
    <option value="Hasselt" class="Brussel">Hasselt</option> 
    <option value="Leuven" class="Brussel">Leuven</option> 
    <option value="Luik" class="Brussel">Luik-Guillemins</option> 
    <option value="Namen" class="Brussel">Namen</option> 
    <option value="Brussel" class="Leuven">Brussel</option> 
    <option value="Gent" class="Leuven">Gent-Sint-Pieters</option> 
    <option value="Hasselt" class="Leuven">Hasselt</option> 
    <option value="Luik" class="Leuven">Luik-Guillemins</option> 
    <option value="Brussel" class="Hasselt">Brussel</option> 
    <option value="Gent" class="Hasselt">Gent-Sint-Pieters</option> 
    <option value="Leuven" class="Hasselt">Leuven</option> 
    <option value="Brussel" class="Charleroi">Brussel</option> 
    <option value="Gent" class="Charleroi">Gent-Sint-Pieters</option> 
    <option value="Brussel" class="Luik">Brussel</option> 
    <option value="Gent" class="Luik">Gent-Sint-Pieters</option> 
    <option value="Leuven" class="Luik">Leuven</option> 
    <option value="Gent" class="DePanne">Gent-Sint-Pieters</option> 
    <option value="Brugge" class="Roeselare">Brugge</option> 
    <option value="Gent" class="Roeselare">Gent-Sint-Pieters</option> 
    <option value="Kortrijk" class="Roeselare">Kortrijk</option> 
    </select> 
    <br/> 
    <input type="submit" value="Go" /> 
</form> 

每個結果都有不同的html.page它必須去。 我想這例如（從安特衛普到根特）：

$('#routeform').submit(function() { 
    if ($('select.station').val() == 'Antwerpen') && ($('select.series').val() == 'Gent') { 
    window.open("contact.html", "_self"); 
    } 
    return false; 
}); 

但它不工作，事先我無法找到問題...

謝謝！

試試這個：

$('#routeform').submit(function (evt) { 
    if (($('select.station').val() == 'Antwerpen') && ($('select.series').val() == 'Gent')) { 
    window.open("contact.html", "_self"); 
    } 
    evt.preventDefault(); // this prevents the submit 
}); 

您的括號是不正確

或

if ($('select.station').val() == 'Antwerpen' && $('select.series').val() == 'Gent') { 

當你沒有包括括號內的if中的語句 - 它仍然有效
