将值传递给函数

Question

我有两个数字GSTIN和PAN

我想匹配GSTIN号码从3到12开始，它将等于PAN号码。

如果匹配

，它应该生成警报

例如

My PAN is : 1234567891

My GSTIN is : aa1234567891bbb

然后是正确的

但是

My PAN is : 1234567891

My GSTIN is : aa7894561239bbb

然后是错误的

我在谷歌搜索但无法找到任何解决方案，这可能吗？请指导我正确的方向。

我尝试使用substr下面的代码，但我无法获得该值

＆＃13;

var pan = document.getElementById("pan");
var unino = document.getElementById("gstin");

var res = unino.substr(2, 11);

document.getElementById("button").addEventListener("click", function() {
    alert( pan.value+'&'+res.value );
});

Answer 1

这是更新的js块，适合你。但这只会验证长度以及GSTIN是否包含PAN。

var pan = document.getElementById("pan");
var unino = document.getElementById("gstin");
document.getElementById("button").addEventListener("click", function() {
    if (!(unino && unino.length == 15 && unino.indexOf(pan) == 2)){
        alert( pan.value+'&'+res.value );
    }
});

我还应该进行正则表达式验证，以确定HTML格式的正确格式。

平底锅的模式应为 - "[A-Za-z]{5}[0-9]{4}[a-zA-Z]"

对于GSTIN应该是 - "[0-9]{2}[A-Za-z]{5}[0-9]{4}[a-zA-Z][0-9]{1}[a-zA-Z]{1}[0-9]{1}"

Answer 2

只需在PAN字符串中搜索GST字符串即可。如果它在PAN中找到GST字符串且索引为2，则表示匹配。否则不是。

希望有所帮助。

您可以使用search方法，如下所示

GST.search(PAN);

Answer 3

我找到了答案。

document.getElementById("button").addEventListener("click", function() {
  var pan = document.getElementById("pan").value;
  
  var unino = document.getElementById("gstin").value;

  var res = unino.substr(2, 10);
  if(pan!=res){
    alert("Wrong GSTIN Number...!");
  }else{
    alert("GST Number is matched.");
  }
});

将值传递给函数

//get value of StateCode / PAN Number / GST Number

var chkGstNum = checkGstNumber(stateCode, panNum, gstNum);
if(chkGstNum == 0) // Error Code
else // Success Code

功能

function checkGstNumber(stateCode, panNum, gstNum)
{
    var GstateCode = gstNum.substr(0, 2);
    var GpanNum = gstNum.substring(2, 12);
    var GEnd = gstNum.substring(12,14);

    if(stateCode != GstateCode)
    {
        alert("Invalid GST Number.");
        return false;
    } 
    if(panNum != GpanNum)
    {
        alert("Invalid GST Number.");
        return false;
    }
    if(GEnd != '1Z')
    {
        alert("Invalid GST Number.");
        return false;   
    }
    if(gstNum.length != 15)
    {
        alert("Invalid GST Number.");
        return false;
    }

    return true;
}
