[英]Assign global variable inside jquery submit function and pass to regex function
Assign value to global tracking variable on submit of form. 在提交表单时向全局跟踪变量分配值。
var tracking;
$('.form-inline').submit(function (e) {
e.preventDefault();
tracking = jQuery('input[name="tracking"]').val();
init()
})
execute function init() 执行函数init()
function init() {
Tabletop.init({
key: public_spreadsheet_url,
callback: showInfo,
simpleSheet: true
})
}
Which initiates the showInfo callback 哪个启动showInfo回调
var zipMatches = "";
function showInfo(data, tabletop) {
alert('Callback initiated..');
for (var i = 0; i < data.length; i++) {
var myRegex = '/' + tracking + '/';
console.log(myRegex)
if (myRegex.test(data[i].tracking)) {
zipMatches = zipMatches + data[i].location_1 + ", " + data[i].location_2 + ", " + data[i].location_3;
}
}
//write it into the DOM
var myElement = document.querySelector(".myJSON");
myElement.innerHTML = "<h3>List of Zipcodes that match tracking ID: </h3><p>" + zipMatches + "</p>";
}
myRegex.test is not a function
myRegex.test不是函数
However regex function works with hardcoded value 但是正则表达式功能可以使用硬编码值
if (/ABCD123/.test(data[i].tracking)) {...
How do I pass the regex value as a global variable? 如何将正则表达式值作为全局变量传递?
.. ..
Edit (working callback function): 编辑(工作回调函数):
function showInfo(data, tabletop) {
var regexp = new RegExp(tracking);
for (var i = 0; i < data.length; i++) {
if (regexp.test(data[i].tracking)) {
zipMatches = zipMatches + data[i].location_1 + ", " + data[i].location_2 + ", " + data[i].location_3;
}
}..
Plese try with following sol: 请尝试以下溶胶:
var regexp = new RegExp(tracking);
and please put it outside of forloop. 并将其放在forloop之外。 So it is optimized.
因此它是优化的。
Since you have tried var regexp = "/" + tracking + "/";
由于您已经尝试过
var regexp = "/" + tracking + "/";
will convert it into string. 将其转换为字符串。 Not regex object.
不是正则表达式对象。 So you won't get test method in it.
因此,您将无法获得测试方法。
Hope it helps :) 希望能帮助到你 :)
