我试图将jQuery元素中的两个值添加到一起,我无法理解我做错了什么。这是我的代码:
$(document).on('pageinit', function() { //init and start function
$("#saveHospital").click(function(){ //run function on button click
var Hospitalval = $("#Hospital").val(); //assign value from element id #Hospital, which is a slider
});
$("#saveICU").click(function(){ //run function on button click
var ICUval = $("#ICU").val(); //assign value from element id #Hospital, which is a slider
var surgicalProc = parseInt(Hospitalval) + parseInt(ICUval); //parse both strings to integers and add them together
$('.P14').html(surgicalProc); //set selector to display the value of the variable
});
这是我的html,其中显示了值:
<p class="P14">Total calculation</p>
我只是得到字符串'total calculation'而不是surgicalProc的值。仅供参考我如果用数字替换正在解析的两个变量,那么函数就可以工作,所以我知道错误在定义的某个地方,但我看不到它。
有什么想法吗?
以下是定义元素的hmtl:
滑
<input type="range" name="Hospital" id="Hospital" value="60" min="0" max="100" />
<input type="range" name="ICU" id="ICU" value="60" min="0" max="100" />
按钮
<a href="#pageThree" id="saveHospital" data-role="button" data-theme="b" data-transition="slide">Submit</a>
<a href="#pageFour" id="saveICU" data-role="button" data-theme="b" data-transition="slide">Submit</a>

我认为您可能正在处理可变范围问题。 Hospitalval
在一个函数中定义,您在另一个函数中调用它。
这可能适合你
var Hospitalval = 0;
$(document).on('pageinit', function() { //init and start function
$("#saveHospital").click(function(){ //run function on button click
Hospitalval = $("#Hospital").val(); //assign value from element id #Hospital, which is a slider
});
$("#saveICU").click(function(){ //run function on button click
var ICUval = $("#ICU").val(); //assign value from element id #Hospital, which is a slider
var surgicalProc = parseInt(Hospitalval) + parseInt(ICUval); //parse both strings to integers and add them together
$('.P14').html(surgicalProc); //set selector to display the value of the variable
});
