问题描述
我面临的Javascript和JQuery一个问题，当我呼吁文本框的的onblur事件的函数它的值乘到其他文本框的另一个价值code正常工作无母版页，但使用主后页我不知道如何当相关控件的ID被传递给函数搜索控制，一个模式的东西使用$（[ID $的jQuery访问控件的ID在母版页=测试]）给我的错误，相关的code.what我想要做的就是乘2的值'txtquan1'和'txtattherate1'和结果存储在lblamnt1当我点击提交按钮值店'lblamnt1获得消失了，我已经googleit并不能找到除了的EnableViewState =真解决方案;但问题仍然存在于目前我使用文本框的jQuery一样..... plz帮助

解决方案
检查该根据您的要求如下：
1，采用的ClientIDMode =在页面指令静态。
从funAmount 2.取出后缀，如控件ID不会有母版页编号追加。
函数funAmount（数量，金额，totalamt）{
变种数量=的document.getElementById（数量）.value的;
VAR AMT =的document.getElementById（量）.value的;
VAR总= parseFloat（数量）* parseFloat（isNaN（AMT）？0：AMT）;
的document.getElementById（totalamt）.innerText = isNaN（总）？ 0：总;
。的document.getElementById（'ddltaxtype'）选项[0] = .selected真;
}
3.Pass的控件功能appropriately.Eg：
＆LT; ASP：文本框ID =txtquan1=服务器的onblur =funAmount（'txtquan1'，'txtatthe1'，'lblamnt1'）＆GT;＆LT; / ASP：文本框＆GT;
＆LT; ASP：文本框ID =txtatthe1=服务器的onblur =funAmount（'txtquan1'，'txtatthe1'，'lblamnt1'）＆GT;＆LT; / ASP：文本框＆GT;
4.Make确保正确的控件ID传递，从code我看到通过了txtatthe2的值不正确。
5.You应该使用网格控件，如果你的行会动态地成长！
i am facing a problem in Javascript and JQuery when i call a function on the "onblur" event of the textbox to multiply its value to another value in other textbox the code works fine without master page but after using master page i don't know how to search for the control when the id of the associated controls is being passed to the function,and one mode thing accessing the id of the control in the master page by JQuery using $("[id$=test]") gives me the error, the associated code.what i want to do is multiply 2 values 'txtquan1' and 'txtattherate1' and store the result in 'lblamnt1' and when i click on the submit button the value store in 'lblamnt1' get vanished,i have googleit and cant find the solution except Enableviewstate=True; but the problem still remains the same for time being i am using jquery on textbox.....plz help
code in aspx file is:
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">

var amt = document.getElementById(suffix + amount).value;
var total = parseFloat(qty) * parseFloat(isNaN(amt) ? 0 : amt);
document.getElementById(suffix + totalamt).innerText = isNaN(total) ? 0 : total;
document.getElementById('ddltaxtype').options[0].selected = "true";
}
function funtax(selectedvalue) {
var value22 = document.getElementById(selectedvalue).value
totalamount = 0;
for (i = 1; i <= 5; i++) {
var val1 = document.getElementById('lblamnt' + i).value;
if (val1 != "") {
totalamount = totalamount + parseFloat(val1);
}
}
var disc = document.getElementById('txtdiscount').value

else if (value22 == 'amount is inclusive of tax') {
document.getElementById('lbltotalamnt').value = totalamount;
var calTax = (totalamount * 100) / 105;
document.getElementById('lbltax').value = parseFloat(totalamount) - parseFloat(calTax);
}
else if (value22 == 'amount is taxable') {
var calTax = (totalamount * 5) / 100;

解决方案
Check if this works according to your requirement:
1.Use ClientIDMode="Static" in the Page Directive.
2.Remove suffix from the funAmount, as control ids will not have the master page id appended.
function funAmount(quantity, amount, totalamt) {
var qty = document.getElementById(quantity).value;
var amt = document.getElementById(amount).value;
var total = parseFloat(qty) * parseFloat(isNaN(amt) ? 0 : amt);
document.getElementById(totalamt).innerText = isNaN(total) ? 0 : total;
document.getElementById('ddltaxtype').options[0].selected = "true";
}
3.Pass the controls to the function appropriately.Eg:
<asp:TextBox ID="txtquan1" runat="server" onblur="funAmount('txtquan1','txtatthe1','lblamnt1')"></asp:TextBox>
<asp:TextBox ID="txtatthe1" runat="server" onblur="funAmount('txtquan1','txtatthe1','lblamnt1')"></asp:TextBox>
4.Make sure the correct control ids are passed,from your code i see the value passed for "txtatthe2" is incorrect.
5.You should be using a grid control if your rows are going to grow dynamically!
