[英]How to change input type to password without key press delay
好的,我在輸入字段中有默認文本作為“ password”,當我按下一個鍵時,我希望它更改為輸入類型“ password”。 但是,當我嘗試執行此操作時,輸入不會注冊我的第一個按鍵,但是會在輸入類型切換之后注冊所有的按鍵。
function inputField(focus, inputValue, inputID){
// change inputID variable into pointer to the actual ID
var iD = document.getElementById(inputID);
// check if input has focus and handle default value changes, password field type changes, and font color changes.
if (focus == "on"){
if(iD.value == inputValue){
iD.setSelectionRange(0, 0);
iD.style.color = "#b2b2b2";
}
iD.onkeypress = function(){
if(iD.value == "password" || iD.value == "retype password"){
iD.type = "password";
}
if (iD.value != "" && iD.value == inputValue){
iD.value = "";
iD.style.color = "#000000";
}
}
}else if(focus == "off"){
if (iD.value == ""){
if(iD.type == "password"){
iD.type = "text";
}
iD.style.color = "#787878";
iD.value = inputValue;
}else if(iD.value == inputValue){
iD.style.color = "#787878"
}
}
}
<input
id = "registerPassword"
class = "loginSectionInput"
type = "text"
name = "rPassword"
value = "password"
onfocus = "inputField('on', 'password', this.id)"
onblur = "inputField('off', 'password', this.id)"
onchange = "formCheck('registerPassword')"
/>
HTML5通過占位符屬性為我們解決了這個問題。 無需再次管理活動...請檢查以下內容
<input type=password name="pwd" placeholder="Password">
您可以用不同的方式來做,這里列出了其中的一些! 希望我能幫助你
假設您有喜歡的領域-
<input type="text" id="mypswfield" name="mypswfield" />
方法1:
您甚至可以在onClick上使用Jquery替換它,
$('#mypswfield').replaceWith('<input type="password" id="mypswfield" />')
方式2:
$("[name=fieldname]").attr("type", "password");
(注意:這是舊的IE中可能會發出的jquery函數,請謹慎操作)
方法3:創建功能
function txtField()
{
if(document.getElementById('mypswfield').value=='')
{
document.getElementById('mypswfield').type='text';
document.getElementById('mypswfield').value='Password';
}
}
function txtPawd()
{
document.getElementById('mypswfield').type='password';
document.getElementById('mypswfield').value='';
}
的HTML
<input id="mypswfield" onclick="txtField();" onblur="txtPawd();" name="mypswfield" type="text" value="Password">
舉個例子:
<html><head><script>function swithch(){
alert("myText is ");
var myText=document.getElementById("myId");
alert("myText is "+myText);
alert("myText is type "+myText.type);
alert("myText is value "+myText.value);
myText.type='text';
myText.value='56789';
}</script></head><body>
TT <input type="password" name="myText" id="myId" value="123456"/> <input type="button" name="switch" value="swithch" onclick="swithch()">
