Asp.net javascript文本框加载值失败 [英] Asp.net javascript Textbox load value failing
问题描述
Hello All，
我新学习asp.net和javascript。
我有今天工作时的一个问题。我在ajax选项卡容器上有13个测试盒，并且在asp.net下拉列表中有4个项目。这是选择，R1，R2，其他。程序如下。
如果用户选择选择则清除所有13个文本框。
如果用户选择R1那么13个文本框应该加载单个值，如txtprodtion = 50，txtqualty = 10等。
如果用户选择R2那么13个文本box应该加载单独的值，例如txtprodtion = 30，txtqualty = 30等。
我在javascript中使用以下功能但未能在文本框上加载文本。< br $>

If user Selects Select then All 13 text boxes shoule be cleared.
If user selects "R1" Then 13 text boxes should load individaul values such as txtprodtion = 50, txtqualty = 10 etc.
If user selects "R2" Then 13 text boxes should load individaul values such as txtprodtion = 30, txtqualty = 30 etc.

推荐答案
（'＃<％= cmbRole.ClientID％ >'）。value;
if （val == R1）{
var textBox = document .getElementById（ txtProduction）;
textBox.value = 50;
}
如果（val == R2）{
var textBox = document .getElementById（ txtProduction）;
textBox.value = 30 ;
}
}
('#<%=cmbRole.ClientID%>').value; if (val == "R1") { var textBox = document.getElementById("txtProduction"); textBox.value = "50"; } if (val == "R2") { var textBox = document.getElementById("txtProduction"); textBox.value = 30; } }
请帮忙。在此先感谢。
