如何获取数字表单值并将其转换为字符串javascript

Question

我想将一个从表单中获得的数字转换为字符串并将其与另一个字符串组合,但我收到了:

windows.location='multiSet?type=multi'Number

相反,我想得到这个:

windows.location='multiSet?type=multiNumber'

请注意,差异是'标记在之前的位置,Number我希望它在之后...

我在其他帖子中看到的是如何将字符串作为数字而不是反之亦然.

var singleMultiContainer = document.getElementById("singleMultiContainer");
var singleMultiValue = singleMultiContainer.value;
var nextButton = document.getElementById("nextButton");
var multipleSetWindow = "window.location='multiSet.html?type=multi'";
var singleSetWindow = "window.location='SampleInfo.html?type=single'";
var containerCuantity = document.getElementById("containerCuantity");

function setContainers(){
    singleMultiValue = singleMultiContainer.value;
    containerCuantityValue = parseInt(containerCuantity.value);
    if (singleMultiValue == "multi"){
        //alert("Multi");
        document.getElementById("nextButton").setAttribute("onclick", multipleSetWindow+containerCuantityValue);

    } else if (singleMultiValue == "single") {
        document.getElementById("nextButton").setAttribute("onclick", singleSetWindow);
    }
}

singleMultiContainer.onchange = function(){
    setContainers();
}

不要setAttribute用于定义事件处理程序.并且您不需要解析该值,因为您希望将其放回字符串中.

更改

document.getElementById("nextButton").setAttribute("onclick", multipleSetWindow+containerCuantityValue);

至

document.getElementById("nextButton").onclick = function(){
      window.location='multiSet.html?type=multi'+containerCuantity.value;
}
