如何在离子中用JS显示跨度
how to display a span with JS in ionic
我已经尝试了很多,只是为了在 ionic 中显示一个简单的变量,但它不起作用?谁能告诉我怎么了?
我已经在代码片段中显示了两种方式...但我终究无法弄清楚自己做错了什么?
localforage.setItem('milk', '0.0', callbackFunction);
var coffee = localStorage.getItem("coffee") ? localStorage.getItem("coffee") : 0.0;
function milkIt(){
milk = milk += 1;
}
function coffeeIt(){
coffee = coffee += 1;
document.getElementById("coffee").innerHTML = coffee;
}
var coffee = localStorage.getItem("coffee") ? localStorage.getItem("coffee") : 0.0;
var totalCoffee = localStorage.getItem("totalCoffee") ? localStorage.getItem("totalCoffee") : 0.0;
var coffeePs = localStorage.getItem("coffeePs") ? localStorage.getItem("coffeePs") : 0;
var cookRate = localStorage.getItem("cookRate") ? localStorage.getItem("cookRate") : 1.0;
$("#coffeeButton").click(function(e) {
var obj = $("#clone").clone();
var img = $("#myImg").clone();
$("body").append(obj);
$("body").append(img);
obj.html("+"+ cookRate);
coffee += cookRate;
totalCoffee += cookRate;
document.getElementById("coffee").innerHTML = prettify(coffee);
document.getElementById("totalCoffee").innerHTML = prettify(totalCoffee);
obj.css('position','absolute');
obj.css('z-index', '2');
img.css('position','absolute');
img.show();
obj.offset({left: e.pageX-10, top: e.pageY-80});
img.offset({left: e.pageX-10, top: e.pageY-50});
obj.animate({"top": "-=80px"}, 1000, "linear", function() {
$(this).remove();
});
img.animate({"top": "-=80px"}, 1000, "linear", function() {
$(this).remove();
});
});
.button{

#coffeeButton{
cursor: pointer; cursor: hand; background: #5EFF8F; border-radius: 7px; margin: 5px; padding: 20px; font: bold 30px Tahoma; text-align: left;
-webkit-touch-callout: none; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; -user-select: none;

<div class = "col">
Milk = <span id = "milk">0.0</span>
</div>
<div class = "col">
Coffee = <span id = "coffee">0.0</span>
</div>
<div class = "row">
<div class = "col"><button on-tap="milkIt()" class="button button-balanced button-block button-large">Milk Cow</button></div>
<div class = "col"><button on-tap="coffeeIt()" class="button button-assertive button-block button-large">Sell Milk</button></div>
</div>
<div id = "coffeeButton">Make Coffee <br /><span id = "cookRate">1</span> Per Click</div>Coffee = <span id = "coffee">0.0</span>
从顶部开始:
localforage.setItem('milk', '0.0', callbackFunction);
callbackFunction 未在任何地方定义。
milk = milk += 1;
"milk +=1;" 与 "milk = milk+1;" 相同,因此您的行表示 "milk = milk = milk+1;"
var coffee = localStorage.getItem("coffee") ? localStorage.getItem("coffee") : 0.0;
这一行重复了。您只能定义一次变量。这应该是 totalCoffee 吗?
到此为止。祝你好运。
