Ios 为什么钛文本字段中的leftButton(或rightButton)不显示?
我为此挣扎了一段时间。似乎是个半虫子 如果将leftButton或rightButton添加到文本字段,如下所示:Ios 为什么钛文本字段中的leftButton(或rightButton)不显示?,ios,uitextfield,titanium-mobile,Ios,Uitextfield,Titanium Mobile,我为此挣扎了一段时间。似乎是个半虫子 如果将leftButton或rightButton添加到文本字段,如下所示: var leftButton = Ti.UI.createButton({ image: 'someImage.png' }) var textField = Ti.UI.createTextField({ leftButton: leftButton, leftButtonMode: Ti.UI.INPUT_BUTTONMODE_ALWAYS,
var leftButton = Ti.UI.createButton({
image: 'someImage.png'
})
var textField = Ti.UI.createTextField({
leftButton: leftButton,
leftButtonMode: Ti.UI.INPUT_BUTTONMODE_ALWAYS,
leftButtonPadding: 100
})
…这样你就看不到你的按钮了。为什么?问题出在leftButtonMode属性中。给它任何值,按钮都不会显示。如果不使用此属性,则按钮将显示正常 对于leftButton,padding属性不是问题。但是如果你在右边的按钮上使用它,它可能会把你的按钮扔到屏幕外面。我也尝试过负面价值观,但没有成功
请注意,leftButton和rightButton选项在Android上不起作用。此代码可能有两个问题。 1-检查指定给按钮的图像路径?(高度、宽度) 出于测试目的,试着使用任何系统按钮,看看它是否出现
var leftButton = Titanium.UI.createButton({
style:Titanium.UI.iPhone.SystemButton.DISCLOSURE
});
2-第二个问题可能是左按钮的填充
试着在没有填充的情况下使用它,然后看看会发生什么
var win = Titanium.UI.createWindow({
title:"Configuring text field and text area keyboard types",
backgroundColor:"#347AA9",
exitOnClose:true
});
//These buttons will appear within the text field
var clearButton = Titanium.UI.createButton({
title:"Clear",
height:24,
width:52
});
var submitButton = Titanium.UI.createButton({
title:"Submit",
height:24,
width:60
});
var textField = Titanium.UI.createTextField({
top:"25%",
height:35,
width:600,
backgroundColor:"#ffffff",
borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED,
hintText:"Type something",
keyboardType:Titanium.UI.KEYBOARD_DEFAULT,
leftButton:clearButton,
rightButton:submitButton
});
clearButton.addEventListener("click", function(e){
//Clear the value of the text field
textField.value = "";
});
submitButton.addEventListener("click", function(e){
//Pretend to submit the value of the text field
//Be sure that you've typed something in!
if(textField.value != ""){
alert(textField.value);
}else{
alert("Enter some text");
}
});
//Add an event listener to the window that allows for the keyboard or input keys to be hidden if the user taps outside a text field
//Note: each text field to be blurred would be added below
win.addEventListener("click", function(e){
textField.blur(); // Cause the text field to lose focus, thereby hiding the keyboard (if visible)
});
win.add(textField);
win.open();
