查找字符串的href，并做一些如果匹配变量

Question

我有一些url字符串以

结尾

&O=07
&O=07&WEEK=14
&O=07&WEEK=15
&O=07&WEEK=16
&O=07&WEEK=17
&O=07&WEEK=18
&O=07&WEEK=19

我定义了一个变量

var liveScoringWeek = 18;

我需要找到url字符串，如果它匹配以下内容。Week18为每周变化的变量

&O=07
&O=07&WEEK=18

我试过了，不工作

if (window.location.href.indexOf("&WEEK=") === liveScoringWeek && window.location.href.indexOf("WEEK=") < 0) {
    alert("found it");
}

Answer 1

这里有一个示例，您可以获得您想要的模式中的任何一个，我们检查是否完全匹配，然后使用||选项创建一个OR命令并检查是否缺少字符串&WEEK=。

条件:

// Returns true if "&WEEK=18" is present in string currentURL
currentURL.includes("&WEEK=" + liveScoringWeek) 
// Returns true if "&WEEK=" is NOT present in string currentURL, i.e. has an index of -1
currentURL.indexOf("&WEEK=") === -1)

带有OR功能的If语句:

// If function requiring either or of two conditions. 
// Replace CONDITION_1 with a true/false qualifier
if ( CONDITION_1 || CONDITION_2 ) {
   ...
}

如果你想要别的东西，请告诉我。

// Store week variable
var liveScoringWeek = 18
// Check URL Function
function checkURL(currentURL) {
  // Check if exact match with week
  // Or no presence of &WEEK= in url
  if (currentURL.includes("&WEEK=" + liveScoringWeek) || currentURL.indexOf("&WEEK=") === -1) {
    // Prove we've found them
    console.log("found it!");
  }
}

// Add test function to buttons
$(".test").click(function() {
  // Check URL taken from button text
  checkURL($(this).text());
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="test">test.com/?something&O=07</button>
<button class="test">test.com/?something&O=07&WEEK=18</button>
<button class="test">test.com/?something&O=07&WEEK=19</button>

Answer 2

您可以尝试includes -function

试试这个:

let currentUrl = window.location.href;
if(currentUrl.includes("WEEK="+liveScoringWeek)){
    console.log("found it!");
}
