驗證結束字母只有

Question

我想在用戶輸入的單詞末尾驗證結尾「uu」，「ha」和「cross」...請參閱「腳本」標籤中的「//」我的意思:)

這是我的HTML表單：

<form name="myForm" action="haha.php" onsubmit="return validateForm()" method="post"> 
    <p id="text">Something: </p> 
    <input type="text" name="form" id="box" > 
    <input type="submit" value="Submit" id="but" > 
</form> 

<p id="check"></p> 

我的Java腳本驗證...

function validateForm() { 
    if(document.myForm.form.value == "") { 
     document.getElementById('check').innerHTML = 'Please fill in the form:) '; 
     return false; 
    } 

    //ok so here's an example of what I'm trying to achieve... 
    if(document.myForm.form.value == endings "uu" "ha" cross") --//please correct- endings "uu" "ha" cross" -- { 
     return true; 
    } 
} 

Answer 1

嘗試使用正則表達式來測試串的一端給出的子串：

if (/(uu|ha|cross)$/.test(document.myForm.form.value)) { 
    return true; 
} 

Answer 2

if(submittedValue.slice(-2) == "uu" || submittedValue.slice(-2) == "ha" || submittedValue.slice(-5) == "cross")  { 
    return true; 
}
