问题描述

限时删除!!

我试图将JQuery值传递给隐藏文本框(稍后以表单的形式发送)以及div前面显示的帽子t $ / b
$ b

。我也想要将这些项目的价值传递给他们。我已经Frankensteined这一点代码传递的价值,输入框和divs,它也符合他们onclick。我只是努力得到总和显示在#total_div。任何人都可以指出我正确的方向吗?

 < script src =https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/ jquery.min.jstype =text / javascript>< / script> 
< script>
$(document).ready(function(){
$('#my_div')。click(function(){
$('#my_value_1')。val(100 );
$('#my_value_1_div')。html(100);
$('#my_div')。click(addNumbers('total'));
});
});

$(document).ready(function(){
$('#my_div_2')。click(function(){
$('#my_value_2')。val (200);
$('#my_value_2_div')。html(200);
$('#my_div_2')。click(addNumbers('total'));
});
});

函数addNumbers()
{
var val1 = parseInt(document.getElementById(my_value_1)。value);
var val2 = parseInt(document.getElementById(my_value_2).value);
var ansD = document.getElementById(total);
ansD.value = val1 + val2;
}
< / script>

< h2>我漂亮的前端< / h2>

< div id =my_div>添加此值1< / div>

< div id =my_div_2>添加此值2< / div>

VALUE 1:< div id =my_value_1_div> VALUE 1 GOES HERE< / div>

VALUE 2:< div id =my_value_2_div> VALUE 2 GOES HERE< / div>

TOTAL:< div id =total_div> SUM必须在这里< / div>

< h2>我的隐藏表格< / h2>

值1:< input type =textid =my_value_1name =my_value_1value =0/>
值2:< input type =textid =my_value_2name =my_value_2value =0/>
< input type =buttonname =Sumbitvalue =Click hereonclick =javascript:addNumbers()/>
总计:< input type =textid =totalname =totalvalue =/>

编辑



好的,谢谢建议我得到了上述工作,但现在我需要清除金额。这是我所做的,它几乎在那里我认为,但我得到了不正确的总和。

  $('#清单')。click(function(){
$('#my_value_1')。val('0');
$('#my_value_1_div')。html(0);
$('#clear')。click(minusNumbers('total'));
});

函数minusNumbers()
{
var minval1 = parseInt(document.getElementById(my_value_1)。
var minval2 = parseInt(document.getElementById(total)。value);
var minansD = document.getElementById(total);
minansD.value = minval2 - minval1;
$('#total_div')。text(minansD.value);


解决方案

更新 #total_div addNumber 函数中的文本,

  function addNumbers()
{
var val1 = parseInt(document.getElementById(my_value_1)。
var val2 = parseInt(document.getElementById(my_value_2).value);
var ansD = document.getElementById(total);
ansD.value = val1 + val2;
$('#total_div')。text(ansD.value);
}




I am trying to pass on JQuery values to hidden textboxes (to send as a form later) as well as divs t

hat displays on the front end. I also want to tally these items as the value is passed to them. I have Frankensteined this bit of code which passes on the value to the the input boxes and the divs and it also tallies them onclick. I am just struggling to get the sum to display in #total_div. Can anyone point me in the right direction please?

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
<script>
$(document).ready(function(){
$('#my_div').click(function() {
$('#my_value_1').val("100");
$('#my_value_1_div').html( "100" );
$('#my_div').click(addNumbers('total'));
});
});

$(document).ready(function(){
$('#my_div_2').click(function() {
$('#my_value_2').val("200");
$('#my_value_2_div').html( "200" );
$('#my_div_2').click(addNumbers('total'));
});
});

function addNumbers()
{
var val1 = parseInt(document.getElementById("my_value_1").value);
var val2 = parseInt(document.getElementById("my_value_2").value);
var ansD = document.getElementById("total");
ansD.value = val1 + val2;
}
</script>

 <h2>My pretty front end</h2>

<div id="my_div">ADD THIS VALUE 1</div>

<div id="my_div_2">ADD THIS VALUE 2</div>

VALUE 1: <div id="my_value_1_div">VALUE 1 GOES HERE</div>

VALUE 2: <div id="my_value_2_div">VALUE 2 GOES HERE</div>

TOTAL: <div id="total_div">SUM MUST GO HERE</div>

<h2>My hidden Form</h2>

Value 1: <input type="text" id="my_value_1" name="my_value_1" value="0"/>
Value 2: <input type="text" id="my_value_2" name="my_value_2" value="0"/>
<input type="button" name="Sumbit" value="Click here" onclick="javascript:addNumbers()"/>
Total: <input type="text" id="total" name="total" value=""/>

EDIT

Ok so thanks to the advice I got the above working but now I need to clear the amounts. This is what I have done, it is almost there I think but I'm getting the incorrect sum.

$('#clear').click(function() {
$('#my_value_1').val('0');
$('#my_value_1_div').html( "0" );
$('#clear').click(minusNumbers('total'));
 });

function minusNumbers()
{
var minval1 = parseInt(document.getElementById("my_value_1").value);
var minval2 = parseInt(document.getElementById("total").value);
var minansD = document.getElementById("total");
minansD.value = minval2 - minval1;
$('#total_div').text(minansD.value);
}
解决方案

Update #total_div text in addNumber function as,

function addNumbers()
{
var val1 = parseInt(document.getElementById("my_value_1").value);
var val2 = parseInt(document.getElementById("my_value_2").value);
var ansD = document.getElementById("total");
ansD.value = val1 + val2;
$('#total_div').text(ansD.value);
}
