基于复选框选中/未选中的文本框值
我的问题很简单,不像看起来那么长。
我有 7 个具有 id text1、text2、text3、text4 和 text5、text6、text7 的文本框和一个具有 id 检查的复选框。我通过 JSON 获取 text1 和 text2 的值,分别为 10 和 20,并在 text7 中显示总计 30。 text4、text5 和text6 的值为空,即这些文本框显示“0”。 text3 和 text4 将根据复选框自动填充。
当我选中该复选框时,“Points”将在 text3 中自动填充,“100”将在 text4 中自动填充。现在text7 总数将显示130。text5 和text6 的值显示“0”。如果我要写一些东西,比如在text5中写“10”,在text6中写“20”,那么text7总计将显示160。如果我取消选中该复选框,则text3和text4的值将被删除,总计将相应更改。我不是选中复选框后能够知道如何自动填充text3和text4,有什么想法吗?
index.jsp
$(document).ready(function() {
$("#combo1").change(function() {
$.getJSON(
'combo1.jsp',
{ combo1Val : $(this).val() },
function(data) {
var a = data.valueoffirsttextbox; //Got 10 from db
var b = data.valueofsecondtextbox; //Got 20 from db
var total = parseInt(a) + parseInt(b);
$("#combo2").val(data.name);
$("#text1").val(a)
$("#text2").val(b)
$("#text7").val(total); // here i am showing total 30 in text7
}
);
// when checkbox is unchecked text4 is not present
$("#text1, #text2, #text5, #text6").keyup(function() {// if any editing occurs
in these values then total will be changed accordingly
var a = $("#text1").val();
var b = $("#text2").val();
var c = $("#text5").val();
var d = $("#text6").val();
var total = parseInt(a) + parseInt(b) + parseInt(c) + parseInt(d);
$("#text7").val(total);// shows total with out text4's value
// when checkbox is checked then text4's value is added
$("#text1, #text2, #text4, #text5, #text6").keyup(function() {// if any editing
occurs in these values then total will be changed accordingly
var a = $("#text1").val();
var b = $("#text2").val();
var c = $("#text5").val();
var d = $("#text6").val();
//here text4 is added
var e = $("#text4").val();
var total = parseInt(a) + parseInt(b) + parseInt(c) + parseInt(d) + parseInt(e) ;
$("#text7").val(total);// show total with text4's value
});
});
});

My problem is simple not so lengthy as looking like.
I have 7 textboxes having ids text1, text2, text3, text4 and text5, text6, text7 and one checkbox having id check. I am getting value of text1 and text2 by JSON as 10 and 20 and displaing total 30 in text7. Values of text4,text5 and text6 are empty that is these textboxes display "0". text3 and text4 will be autofilled based on checkbox.
When i checked the checkbox then "Points" will be autofilled in text3 and "100" will be autofilled in text4. Now total text7 will show 130. Values of text5 and text6 display "0". If i will write something let's say "10" in text5 and "20" in text6 then total text7 will show 160. If i uncheck the checkbox, then values of text3 and text4 will be removed and total will be changed acordingly.I am not able to know how to autofill text3 and text4 after checking the checkbox, any idea please?

只需为 text3 添加另一个 if/else 即可。简单的。
