[英]Passing data from HTML to JS function
I have a series of data points that I query for status and voltage, and want to use a function to display as readable data in a table .我有一系列数据点,用于查询状态和电压,并希望使用函数在表格中显示为可读数据。
I can't seem to get how to pass the register data to the fnction , and then return the processed data to the table .我似乎不明白如何将寄存器数据传递给 fnction ,然后将处理后的数据返回到 table 。
Here's the test code,下面是测试代码
<input type="hidden" id="reg120" name="reg120" readonly value="%d">
<input type="hidden" id="reg121" name="reg121" readonly value="%d">
<script language="javascript">
function dsestate(regn) {
var state = ["STOP MODE","AUTO MODE","MANUAL MODE","TEST ON LOAD","AUTO MAN","USER CONF","TEST OFF LOAD","OFF"];
return state[regn];
}
</script>
<script language="javascript">
function divby10(regn1) {
return regn1/10;
}
</script>
<table id="maintable" style="width:75%">
<tr>
<th>Site</th>
<th style="width:180px">Status</th>
<th style="width:180px">Voltage</th>
</tr>
<tr>
<td><input type="text" id="dsestate(reg120)"></td>
<td><input type="text" id="divby10(reg121)"></td>
</tr>
</table>
</body>
</html>
Any help would be appreciated.任何帮助,将不胜感激。
divBy10's argument should be a number (so it could be divided by 10). divBy10 的参数应该是一个数字(所以它可以被 10 整除)。 dsestate's argument should also be a number so you can get the object by the index of the state Array (ie state[1]).
dsestate 的参数也应该是一个数字,以便您可以通过状态数组的索引(即 state[1])获取对象。
And since you're calling a javascript function, it should also use onload=, rather than id=.并且由于您正在调用一个 javascript 函数,它也应该使用 onload=,而不是 id=。
I hope that gives you a starting point, good luck!我希望这能给你一个起点,祝你好运!
