[英]Trouble shooting jquery enable/disable text box based on radiobutton
[英]Trouble shooting jquery enable/disable text box based on radiobutton again
正確處理此部分后,(( 根據單選按鈕故障排除jquery啟用/禁用文本框 )我發現我需要在表單中添加另一個字段,如果選擇了單選,也將其禁用。
似乎已經破壞了整個問題,我找不到問題所在。
我已經重寫了代碼以嘗試並理解它(我一點也不懂javascript)
<input type="radio" name="radioknof" value="public" CHECKED/>
<label for "public">Anyone</label>
</br>
<input type="radio" name="radioknof" value="direct" />
<label for="direct">Specific</label>
</br>
<label for="newManagerFirstName">Manager's Firstname :</label>
<input type="text" name="newManagerFirstName" id='newManagerFirstName' value="1">
</br>
<label for="newManagerEmail">Manager's email address:</label>
<input type="text" name="newManagerEmail" id='newManagerEmail' value="2">
接着
$(window).load(setDefault());
$('input[name=radioknof]').on('click', UnOrLock());
function setDefault() {
$("#newManagerEmail").prop("disabled", true);
$("#newManagerFirstName").prop("disabled", true);
}
function UnOrLock() {
if (this.checked && this.value == "public") {
$("#newManagerEmail").prop("disabled", true);
$("#newManagerFirstName").prop("disabled", true);
} else {
$("#newManagerEmail").prop("disabled", false);
$("#newManagerFirstName").prop("disabled", false);
}
}
請告訴我我所缺少的...?
這是一個更清潔的解決方案: http : //jsfiddle.net/8Jn44/
使用disabled
屬性而不是使用腳本的禁用的輸入字段。
<input type="text" name="newManagerFirstName" id='newManagerFirstName' value="1" disabled>
<input type="text" name="newManagerEmail" id='newManagerEmail' value="2" disabled>
JS函數:(:radio是可選的)
$("input:radio[name='radioknof']").on('click',function () {
if (this.checked && this.value == "public") {
$("#newManagerEmail").prop("disabled", true);
$("#newManagerFirstName").prop("disabled", true);
} else {
$("#newManagerEmail").prop("disabled", false);
$("#newManagerFirstName").prop("disabled", false);
}
});
就像Banana所說的那樣,需要做一些調整,將id放在單選按鈕上,每次都驗證代碼,有時您看不到http://validator.w3.org/這個問題,我不認為w3school是最好的網站開始www.w3fools.com,Mozilla Mdn會變得更好https://developer.mozilla.org/docs/Web/JavaScript網上也有很多電子書。
Nikhil的解決方案很好,您可以將其減少一點:
$(document).ready(function(){ $('[name=radioknof]').click(function(){ if (this.checked && this.value == "public") { $("#newManagerEmail, #newManagerFirstName").prop("disabled", true); } else { $("#newManagerEmail, #newManagerFirstName").prop("disabled", false); } }); });
我建議以下內容:
// selecting inputs whose 'type' attribute is equal to 'radio':
$('input[type="radio"]')
// binding change-event handler to those elements:
.on('change', function () {
// selecting the relevant elements to be affected:
$('#newManagerEmail, #newManagerFirstName')
// updating the 'disabled' property of those selected elements,
// if the changed radio-input is checked *and* its value is 'public',
// the disabled property is set to true (it's disabled), otherwise it's
// false and the input is enabled:
.prop('disabled', (this.checked && this.value === 'public'));
// triggering the 'change' event, to ensure the inputs are disabled/enabled
// appropriately:
}).change();
