[英]How to make array for a .push function. Getting “typeError: .push is not a function”?
I'm having trouble understanding how my code is resulting in an error. 我无法理解我的代码是如何导致错误的。 The line that gives off an error is
发出错误的行是
queryParts.push("&" + param + "=");
I can see that it inserts an array, but I don't understand how to make it an arrow and push. 我可以看到它插入了一个数组,但是我不明白如何使它成为箭头并推动。
function urlBuilder(param, paramValue){
base_url = $('.service-container').data('base_url');
var fullurl = window.location.href;
var urlStart = fullurl.split("?").length > 1 ? fullurl.split("?")[0] : null;
var urlQuery = fullurl.split("?").length > 1 ? fullurl.split("?")[1] : null;
if (urlQuery) {
var queryParts = urlQuery.split('&');
for (var i = 0; i < queryParts.length; i++)
{
console.debug('query part: ', queryParts[i]);
if (queryParts[i].includes(param)) {
if (paramValue === null) {
queryParts.splice(i, 1);
} else {
queryParts = "?" + param + "=" + paramValue;
}
} else {
queryParts.push("&" + param + "=");
}
}
var rtnUrl = urlStart + queryParts.join("&");
return rtnUrl;
}else {
return base_url + '?' + param + '=' + paramValue;
}
}
You do 你做
queryParts = "?" + param + "=" + paramValue;
After this, queryParts
isn't an array anymore. 之后,
queryParts
不再是数组。
You probably wanted 你可能想要
queryParts.push( "?" + param + "=" + paramValue);
This line makes your queryParts
string. 这
queryParts
您的queryParts
字符串。
queryParts = '?' + param + '=' + paramValue
To keep it array: 保持数组:
queryParts.push('?' + param + '=' + paramValue)
