如何获取输出中显示的值,并将其设置为变量,以便我可以将其乘以另一个变量?
let calculate = () => {
let box1_selection = getValueById("pattern");
let box2_selection = getValueById("thick");
if (box1_selection == "" || box2_selection == "") {
document.getElementById("output").innerHTML = "Please select both values";
} else {
let value = "not specified";
/*if(box2_selection == 0 && box3_selection == 0 {
value = "$27.00";
} else if(box2_selection == 0 && box3_selection == 1) {
value = "$17.00";
}*/
var lolm = getPrice(box1_selection, box2_selection);
document.getElementById("output").innerHTML = lolm;
}
}
var getValueById = (id) => {
var selection = document.getElementById(id);
return selection.options[selection.selectedIndex].value;
}
var getPrice = (value_1, value_2) => {
// price_data is a 3 dimensional array.
var price_data = [
[
[8.00],
[13.50]
],
[
[20.80],
[22.05]
],
[
[53.10],
[99]
],
[
[20.20],
[99]
],
[
[24.00],
[99]
],
[
[99],
[99]
],
[
[15.23],
[99]
]
];
return price_data[value_1][value_2];
var roundedvalue1 = Math.ceil(document.getElementById('box3').value);
var roundedvalue2 = Math.ceil(document.getElementById('box4').value);
if (roundedvalue1 % 2 != 0) {
roundedvalue1 += 1;
}
if (roundedvalue2 % 2 != 0) {
roundedvalue2 += 1;
}
var result = document.getElementById('result');
var rounded1plus2 = (roundedvalue1 + 2)
var rounded2plus2 = (roundedvalue2 + 2)
var squareFoot = (rounded1plus2 * rounded2plus2 / 144)
var myResult = +lolm;
result.value = myResult;
}
<select id="pattern" onchange="calculate()">
<option value="">Select Glass Pattern</option>

<option value="0">3/8 (10mm)</option>
<option value="1">1/2 (12mm)</option>
</select>
<td><input id="box3" type="text" oninput="calculate()" placeholder="Whole #'s" maxlength="3" size="4" /></td>
<td><input id="box4" type="text" oninput="calculate()" placeholder="Whole #'s" maxlength="3" size="4" /></td>
<td><b>$</b><input id="result" maxlength="4" size="4" />Flat</td>

<div id="output">Please select both values</div>
<div>
</div>
基本上我要做的是抓取网页上显示的输出作为实际文本,set等于随选择而变化的变量,我可以乘以其他部分的其他变量脚本。
答案 0 :(得分:0)
我没有完全理解你想要的东西。这是我的解决方案,如果有帮助的话。
您已经在此行中获得了输出值
var lolm = getPrice(box1_selection, box2_selection);`
它已设置为lolm
。你可以随意操纵。
您已在lolm
箭头功能中将calculate
声明为var lolm
。所以它的函数作用域,如果你想在函数外部访问它(在其他函数中使用它)全局声明变量lolm
(在函数之外)。
