如何在javascript中将值作为参数传递
[英]How to pass values as parameters in javascript
问题描述
I am working on a test project to learn web development and have run into a problem that I am not sure how to solve. 
我正在研究一个测试项目来学习Web开发，并遇到了一个我不确定如何解决的问题。
I have a table that contains 11 cells. 我有一个包含11个单元格的表。 9 of the cells have predefined values in them, however, for the other two I would like to manually set the value through passing values to parameters. 其中9个单元格中有预定义值，但是对于其他两个单元格，我想通过将值传递给参数来手动设置值。
The code; 编码;
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Colour Match</title>
</head>
<body>
<table width="300" border="1" id="menuitems">
<tbody>
<tr>
<td id="cell1"><div> RED</div></td>
<td id="cell2"><div> BLUE</div></td>
<td id="cell3"><div> GREEN</div></td>
</tr>
<tr>
<td id="cell5"><div> PINK</div></td>
<td id="cell6"><div> PURPLE</div></td>
<td id="cell7"><div> YELLOW</div></td>
</tr>
<tr>
<td id="cell9"><div> BLACK</div></td>
<td id="cell10"><div> BROWN</div></td>
<td id="cell11"><div> GREY</div></td>
</tr>
</tbody>
</table>
<table width="300" border="1" id="menulist">
<tbody>
<tr>
<td id="colourname"><div> colour name</div></td>
</tr>
<tr>
<td id="colour"> colour</td>
</tr>
</tbody>
</table>
</body>
</html>
I have given ids to each cell and what I would like to do is, change the value of the bottom two cells 'colourname' and 'colour' depending on what cell user clicked, however, I would like to manually pass values to javascript parameter when I call it on click; 我已经为每个单元格提供了id，我想要做的是，根据用户点击的单元格更改底部两个单元格'colourname'和'color'的值，但是，我想手动将值传递给javascript参数当我点击它的时候; Something like this; 像这样的东西;
</script> <td id="cell1" onClick="mySetup("RED", Color:RED)"><div> RED</div></td>
I don't have much knowledge of Javascript but I have some knowledge of java and this is roughly how it can be achieve in java: 我对Javascript知之甚少，但我对java有一些了解，这大致是如何在java中实现的：
TextField someID;
Button SomeID;
Public mySetup (String colourName, Color colour) {
someID = colourName;
someID.setBackgroundColor(colour)
}
What I want to do is set up a function in javascript that when called onClick takes in values as parameter and changes the bottom two cells: 我想要做的是在javascript中设置一个函数，当调用onClick时，将值作为参数并更改底部的两个单元格：
I am sure this isn't the correct way of doing it in JS but just to explain my question better: 我确信这不是在JS中这样做的正确方法，而只是为了更好地解释我的问题：
Function mySetup (Var name, Color colour) {
colourName.setVar(name);
colour.setColour(colour);
}
I hope I have explained myself properly, if not please let me know and I will try to explain better. 我希望我已经正确解释了自己，如果没有，请告诉我，我会尽力解释。
EDITED: 编辑：
colourName should change the text of the cell, whereas colour should change the background colour of the cell. colourName应更改单元格的文本，而颜色应更改单元格的背景颜色。
EDITED 2 编辑2
Hi, I think my question did not come as clear as I wanted it to be; 嗨，我认为我的问题没有像我希望的那样明确;
The parameter of the function should take in two values, 1 for colourName and 1 for the backgroundcolour. 函数的参数应该包含两个值，1表示colourName，1表示backgroundcolour。
the colourName should change the text of colourname cell and backgroundcolour should change the background for colour for colour cell. colourName应更改colourname单元格的文本，backgroundcolour应更改颜色单元格的颜色背景。
<td id="colourname"><div> colour name</div></td>
</tr>
<tr>
<td id="colour"> colour</td>
</tr>

function f(col, name) { $("#colourname div").html(name); $("#colour").css('background-color', col); }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table width="300" border="1" id="menuitems"> <tbody> <tr> <td id="cell1" onclick="f('RED', 'name RED')"><div> RED</div></td> <td id="cell2" onclick="f('BLUE', 'name BLUE')"><div> BLUE</div></td> <td id="cell3" onclick="f('GREEN', 'name GREEN')"><div> GREEN</div></td> </tr> </tbody> </table> <table width="300" border="1" id="menulist"> <tbody> <tr> <td id="colourname"><div> colour name</div></td> </tr> <tr><td id="colour"> colour</td></tr> </tbody> </table>

First your click event call should be like this. 首先，您的点击事件调用应该是这样的。
<td id="cell1" onClick="mySetup('RED')"><div> RED</div></td>
and JS : 和JS：
UPDATE : 更新 ：
function mySetup(Color) {
var arr = {
"RED": {
"colornam": "red",
"color": "red"
},
"GREEN": {
"colornam": "blue",
"color": "blue"
},
"BLUE": {
"colornam": "green",
"color": "green"
}
}
var colourname = document.getElementById('colourname');
var colour = document.getElementById('colour');
var coloName = arr[Color];
colour.style.background = coloName.color;
colourname.innerHTML=coloName.colornam;
}
Please see the updated fiddle 请看更新的小提琴
UPDATE2 : 更新2 ：
td id="cell1" onClick="mySetup('RED','red')"><div> RED</div></td>
JS: JS：
function mySetup(Color,colorName) {
var colourname = document.getElementById('colourname');
var colour = document.getElementById('colour');
colour.style.background = Color;
colourname.innerHTML=colorName;
}

Write a simple function 写一个简单的函数
Javascript 使用Javascript
function mySetup(CoulourName, Color){
var colourname = document.getElementById('colourname');
var colour= document.getElementById('colour');
colourname.innerHTML = CoulourName;
colour.style.background = Color;
}
HTML HTML
And use onClick = "mySetup('FANCY NAME','RED');" 并使用onClick = "mySetup('FANCY NAME','RED');" on td and so on for others with diferent color name. 在td等等其他颜色名称不同的人。

You can try this : 你可以试试这个：
<td id="cell1" onClick="mySetup('RED', '#FF0000')"><div> RED</div></td>
var Color = new Object(); var Color = new Object（）;
function mySetup (name, colourCode) { function mySetup（name，colourCode）{
Color.name = name;
Color.colorCode = colourCode;
} }
